1900 Series Conventional Safety Relief ValvesSteel, Flat Seat, Top Guided, High Capacity, Stainless Steel TrimThis standard rugged configuration is equipped with corrosion resistant trim and a carbon steel body, bonnet and cap. The components are top guided, providing for free and repeatable action.The flat disc seat provides for easy maintenance and remachining.The exclusive Eductor Tube minimizes bonnet cavity pressure so that product performance is predictable.The nozzle is bottom inserted and rigidly held in position, providing a corrosion resistant path of flow to the valve and corrosion resistant seating surfaces.

1900-30 Series Bellows ConstructionThis valve is the same as the conventional design except that a bellows has been added. When the bellows is installed, the eductor tube is removed.Caution: It is important that the bonnet be vented to the atmosphere.

A bellows is added to the conventional valve to deal with any of several situations:(1) Back pressure entering the valve through the valve outlet is excessive or variable. If back pressure fluctuates with 10% of a nominal value, a bellows is required.If a built up back pressure exceeds 10% of the set pressure or cold differential set pressure, a bellows must be used.(2) If the entering fluid is a slurry, highly viscous, or of a nature that it can enter the critical clearances between the guides/disc holder, protect that area with a bellows.(3) If the fluid being handled is corrosive to the upper works of the valve, isolate the bonnet chamber through use of a bellows.Conventional valves can be easily converted to a bellows design or vice versa through the use of retrofit kits.All CONSOLIDATED 1900-30 Series valves are balanced bellows designs, meaning that they fully compensate for the effects of back pressure.

1900-35 Series Balanced Bellows (with Auxiliary Balancing Piston)The Balanced Bellows seals the body and fluid stream from the bonnet and working parts. Auxiliary balancing piston assures proper valve performance by compensating for back pressure in case of bellows failure.The use of an auxiliary balanced piston is indicated when:(1) back pressure (either constant or variable) exists and;(2) excessive pressure may build in the bonnet as a result of pressure build - up in the bonnet vent piping and; (3) resultant build - up of pressure in the bonnet would cause a dangerous condition.Caution: It is important that the bonnet be vented to the atmosphere.

NOTE: Unless otherwise stated the valve is always supplied with a screwed cap. The exception to this would be where ASME B & PVC, Section VIII requires levers for steam, air, and hot water service over 140F.

Refer to Accessories for available types of caps, levers, and accessories.

All pressure relief valves operate on the principle of inlet system pressure overcoming a spring load, allowing the valve to relieve a defined capacity.

When the valve is closed during normal operation (See Figure 1900.1), the vessel pressure acting against the seating surfaces (area A) is resisted by the spring force. As vessel pressure increases, the pressure at A tends to equalize the spring force and the pressure holding the seats together approaches zero.

orifice, pressure builds up in chamber B (See Figure 1900.2). Since pressure can now act over a larger area, an additional force is available to overcome the spring force. By adjusting the adjusting ring the opening in the secondary annular orifice can be altered, thus controlling pressure build-up in chamber B. This controlled pressure build - up in chamber B will overcome the spring force causing the disc to move away from the nozzle seat and the valve to pop open.

In vapor or gas service the valve may simmer before it will pop. When the vessel pressure increases to within one to two percent of the set pressure, media will audibly move past the seating surfaces into chamber B. As a result of restriction of flow in the secondary annular

Once the valve has opened an additional pressure build-up at C occurs. (See Figure 1900.3.) This is due to the sudden flow increase and the restriction to flow through another annular orifice formed between the inner edge of the disc holder and the outside diameter of the adjusting ring. These additional forces at C cause the disc to lift substantially at pop.Flow is restricted by the opening between the nozzle seat and disc seat until the disc seat has been lifted from the nozzle seat approximately one - quarter of the nozzle throat diameter. After the disc has attained this degree of lift, flow is then restricted by the primary orifice rather than by the area between the seating surfaces.Blowdown (the difference between opening and closing pressure) can be controlled within limits by positioning the single adjusting ring. Blowdown is caused by the result of the spring force not being able to overcome the summation of the forces at A, B, and C until the pressure at A drops below the set pressure.

Figure 1900.4 reflects the flow path of fluid through the valve. It is significant to recognize that the system pressure enters through the nozzle and remains at a high pressure until it expands through the secondary annular orifice. Pressure downstream of the secondary annular orifice is much lower than the system pressure. The upper

portion of the valve base plus the outlet flange are of a lower pressure rating than the inlet side of the valve.

NOTE: BLOWDOWN SETTINGS - Production testing required by Manufacturers of safety relief valves is governed by ASME Section VIII, UG -136 (d), which does not require the setting of blowdown during production test. Adjusting rings on the 1900 flanged safety relief valve series are factory adjusted to predetermined ring settings. This will provide a consistent opening and closing pressure on the safety relief valve.

Adjusting RingThe adjusting ring in the CONSOLIDATED safety relief valve is preset to predetermined positions prior to putting the valve in service. Presetting reduces the necessity of popping the valve in service to ascertain that the ring has been set properly for attaining the necessary lift and relieving capacity.

Simple Blowdown AdjustmentAdjustment of CONSOLIDATED safety relief valve blowdown, or reseating pressure, is by means of a single adjusting ring. When moved upward, blowdown is increased (lowering the reseating pressure), or when moved downward, the blowdown is decreased (raising the reseating pressure). The simplicity and advantages of this adjustment are obvious when comparing valves having two or more adjusting rings each of which affect valve action as well as blowdown.

Minimum Guiding AreaGuiding areas greater than those required to align the seating surfaces are undesirable in a safety relief valve, especially those used in the process industries. The smaller the guiding area of the valve (when corrosion or contamination from the flowing medium build up in the valve guiding surfaces) the less tendency the guiding area will have to stick and hinder valve operation.

NozzleThe nozzle is a pressure containing component in constant contact with the process media in both the open and closed valve positions. To ensure maximum reliability and safety, CONSOLIDATED flanged SRV nozzles are made from forgings, investment castings, or centrifugal castings.

Spindle Pocket ConnectionThe connection between the spindle and disc holder in a CONSOLIDATED safety relief valve is a positive method of attachment. The Inconel snap ring and groove design make it virtually impossible to remove the spindle from the disc holde, unless the ring is compressed intentionally. This design requires a minimum amount of effort to disassemble during maintenance.

Design SimplicityCONSOLIDATED safety relief valves embody a minimum number of component parts which results in a savings by minimizing spare parts inventory and simplifying valve maintenance.

Maximum Seat TightnessSeat finish in a safety relief valve is of the utmost importance; otherwise, valve leakage will occur.CONSOLIDATED safety relief valve seats are precision machined and lapped. This ensures positive seating and prevents loss of contained media.The Thermodisc design provides a tighter closure and compensates for temperature variations around the periphery of the nozzle. Thermal distortion, which produces seat leakage, is minimized in steam service.

Cap and Lever InterchangeabilityMany times it is necessary to change the type of cap or lever in the field after a valve has been installed. All CONSOLIDATED safety relief valves are supplied so they can be converted to any type of lever or cap desired. It is not necessary to remove the valve from the installation, nor will the set pressure be affected when making such a change.

Valve InterchangeabilityA CONSOLIDATED safety relief valve may be converted from the standard, conventional type valve to the bellows type, or to the O -Ring seat seal type, Thermodisc seat Liquid Trim, or vice versa, requiring a minimum number of new parts. This results in lower costs.

Quality MaterialAll CONSOLIDATED safety relief valve castings and forgings are made to ASTM/ASME specifications and are subject to many rigid inspections, ensuring the highest degree of quality.Coupled with the highest quality workmanship, this ensures continuous protection and long, trouble-free valve life.

Reduction of Valve Bonnet PressureClosed bonnet valves are subject to variable pressure past the guiding surfaces when the valve is open, which adds a variable force to that of the spring, affecting valve performance. To eliminate excess bonnet pressure and ensure good valve opening and closing action, an Eductor Tube is provided.The Eductor Tube reduces bonnet pressure by pulling discharging fluids out of the bonnet faster than it is possible for the discharging fluids to enter past the guiding surfaces, acting as a siphon due to the drawing effect of the flow through the outlet side of the valve.

Eductor Tube Reduces Bonnet PressureAn exclusive with CONSOLIDATED valves! During valve discharge, media flows through the clearance between the disc holder and guide, building up bonnet pressure. This adds a variable force to the spring force, which inhibits valve lift. Bonnet pressure is reduced by the eductor effect of the medium flowing at high velocity at the valve outlet.The greater lifting force (resulting from a reduction in bonnet pressure) introduces important advantages:

(1) Response to blowdown control adjustment is uniform (2) Positive, full - rated capacity at low overpressures is assured (3) Better operation at higher back pressures with Eductor Tube. (4) Complete stability (of valve lift and capacity) is assured during operation. (5) Increases the lifting force when the valve opens and tends to break slight corrosive deposits or surface film which accumulate on the guiding

surfaces and retard valve action. (For severe corrosion applications, a bellows valve is recommended.)

This concept has more than 40 years of field proven performance that ensures the tightest valves in the world.A Thermodisc is required for steam service.

The Martensitic stainless steel disc construction allows for high strength and toughness. As the set point of the valve is approached, the pressure sealing effect of the Thermodisc assists in the tightness of the seat as does the rapid thermal equalization that occurs due to the thin sealing section.

The Liquid Trim LA (liquid application) represents the second generation of ASME B & PVC, Section VIII certified liquid trim valves and must be used for all liquid applications for both ASME B & PVC, Section VIII certified and non-certified valves. Liquid applications have been defined as follows:

(1) if the fluid remains liquid while flowing through the valve

(2) if flowing fluid flashes going through the valve

(3) for ASME B & PVC, Section VIII certified and non-certified thermal

relief applications. (Thermal Relief is to prevent excessive pressure caused by thermal expansion of trapped liquids). The LA trim provides blowdown performance with ranges from 7% to 12% below the set pressure. This valuable feature provides conservation of media, a positive lift and a smooth chatter - free operation. Because of the short blowdown performance of this design, it is critical that the inlet connection always provide for a pressure drop of 3% or less from the vessel to the valve as recommended by API 520.

Conversion of existing 1900 Series valves to liquid trim is available through the factory or your local Green Tag Center.

D and E Orifice Only

The 1900 series is offered in orifice sizes ranging from the smallest D size to the largest W size. In order to accomplish certain valve functions some special considerations have to be made. Such a case is the D and E orifice designs noted below.The D and E valves are restricted lift versions of the F orifice valve. The lift is restricted by a limit washer to provide the equivalent effective orifice area for a D or E orifice. This design is available with a balanced bellows configuration and is designed for back pressure applications.The standard 1900 Series are available with restricted lifts in orifices ranging from F to W for compressible media only.

Closeness of Operating Pressure to Set PressureWhere the operating pressure is close to the set pressure, seat tightness can be maintained at relatively higher operating pressures.

Compressor Discharge and Positive Displacement Pump ServiceMechanical vibration and pressure waves could lift the valve disc with each stroke and may cause flat metal - to -metal seats to rub together and become damaged.The 45 metal - to -metal load bearing seats in the CONSOLIDATED O-Ring seat seal assure true alignment, aided by full system pressure behind the O-Ring, which effectively seals against leakage.

Corrosive ServicesIn some services, corrosion of the seating surfaces is the cause of vaIve leakage. In this type of service, the CONSOLIDATED O-Ring seat seal will protect the metal seat on the nozzle against contact of the corrosive fluid thereby maintaining greater tightness.

Foreign Matter and Slurry ServiceMany times foreign material such as pipe scale, welding beads, sand dust particles, etc. may damage the metal - to -metal seating surfaces in a valve of this type when it is open and flowing.The CONSOLIDATED O-Ring seat seal is designed to absorb the impact of most foreign particles without damage.

Hot Water Boiler ServiceWhen a safety relief valve opens hot water flashes into steam at the seating surfaces and solid particles which float to the water surface are driven against the seating surfaces at steam velocities. CONSOLIDATED O-Ring seat seal valves can withstand this type of service and remain tight to a greater degree than metal - to -metal seat valves.CONSOLIDATED uses proven quality Teflon O-Ring seats for this service. In some pressure/temperature applications, Teflon is not resilient, and leakage may occur.

BenefitsSafety Relief Valve leakage which is aggravated by any cause is usually costly. In many cases, expensive product is lost and maintenance costs increased. CONSOLIDATED O-Ring seat seal valves are designed to eliminate leakage in troublesome applications and reduce overall costs. Should leakage occur, it is much simpler and less expensive to replace the O-Ring than to maintain metal - to -metal seats.

O-Ring Conversion1900 Series CONSOLIDATED metal seated valves can be converted to O-Ring seat seals by installing a few basic parts provided in a conversion kit.

The Double Seal Soft SeatThe double seal design incorporates the merits of both a soft seat and a metal seat design valve. The 45 metal seat provides the load bearing surface to transmit spring force, the slotted O-Ring retainer allows the O-Ring to be pressurized and accomplish the primary sealing function. This O-Ring seal design can be used throughout the full pressure range of the valve. For pressure/temperature ratings of the seal, refer to O-Ring Selection Table in this section (pages 1900.35 and 1900.36).Tightness: CONSOLIDATED O-Ring seat seal valves are bubble tight at 95% of set pressures over 100 psig.The following table reflects the percent of set pressure (popping pressure) at which the valve will be bubble tight on air.

CONSOLIDATED O-Ring seat seals provide positive closure at service pressures closer to the set pressure than is possible with metal - to - metal seats assuring continuous, trouble-free service, and complete valve tightness after numerous pops.

NOTE: The CONSOLIDATED 1900 O - Ring design features a secondary metal-to-metal seat which becomes effective if O - Ring integrity is lost due to external fire or other causes. The retainer is lapped to the nozzle at assembly assuring seat tightness.

The nozzle bore and O - Ring retainer are both machined to an angle of 45. This ensures that as the valve disc opens and closes, the O - Ring is aligned concentrically against the lip of the nozzle. Close tolerance between the nozzle and the body, or the body and the disc guide and disc holder, also help to ensure a tight seal when the valve is closed. Accurate alignment coupled with the load bearing function of the O - Ring retainer virtually eliminates O - Ring abrasion from valve action.

'BVm^bjbHZVa^c\;dgXZ

On the back side of the O - Ring retainer there are two small slots. When the valve is closed, process media enters between the machined seat of the nozzle and the O - Ring retainer and proceeds up the slots behind the O - Ring. This pressure forces the O - Ring against the lip of the nozzle and the curved recess of the disc holder. As the pressure within the valve rises to set point, the O - Ring is pressed tightly against the nozzle to maintain maximum sealing force until break- away pressure is reached.

(D"G^c\GZiZci^dc

When the valve opens, the pressure behind the O - Ring escapes from the same two slots on the O - Ring retainer. This prevents the O - Ring from being ejected. Additionally, the O - Ring encapsulating retainer prevents the O - Ring from being pulled from its setting by the high velocity, low pressure discharge inside the upper valve body.

Three Essentials to a Tighter and More Secure Seal:

Two unique features distinguish the CONSOLIDATED O - Ring seat seal safety valve from other designs. These are the 45 metal - to -metal load bearing seats and the slotted O - Ring retainer.
