FEATURES DBBV

Features Control Seal™ Double Block and Bleed ValvesFriction FreeAn important aspect of a valve is the sealing mechanism. Almost all valves, like standard Ball, Gate and Butterfly valves have their sealing mechanism based upon shear force, friction and tearing. The Control Seal ™ sealing mechanism is based upon a radial movement only. The sealing is not liable to shear, friction or tearing. This means no abrasion on the seal and compared to other type of valves, results into an exceptional long lifetime.

Double Block and BleedControl Seal ™ valves have a double block and bleed function up and downstream. Normally this can only be achieved by using two (2) valves and a spool piece with a drain valve. The use of a Control Seal ™ Double Block and Bleed Valve will safe cost, space and maintenance for a long period.

In-Line Maintenance and ServiceAs the Control Seal ™ valve is designed for easy and low cost maintenance Stem packings can be adjusted while the valve is in service. All valves are executed with a back seat. Bottom and top entry is possible while the valve is inline. No special tools are required.

Non-SlamThe self-locking operate mechanism on all Control Seal ™ valves, provides that the closing member (plug) cannot rotate due to line forces. Therefore there is no danger of line slam, shock or injury of personnel.

Fire SafeThe Control Seal ™ valves have been Fire safe tested by independent laboratories and has passed the test to BS 6755 part 2 and API 6FA succesfully. These tests have been wittnessed by Lloyds on several valves.

Advantages of the Control Seal ™ Design.► Friction free opening and closing, increasing the lifetime of the valve.► Corrosion and wear resistant materials are used on the closure members.► Bottom and top access for inline inspection and maintenance.► Adjustable stem packing while the valve is in service.► All valves are executed with a backseat, which gives the possibility to renew stem packing under pressure.► Non lubricated seal.► Pressure independent sealing.► No coupling cam in the stem construction.► Topworks according to ISO 5210

Optional Valve Executions► Control Seal ™ valves can be supplied in a variety of materials and are also available in accordance with DIN standards.► Stem extensions and gas column for cryogenic service► Control Seal ™ Double Block and Bleed Valves can be supplied with various types of Viton, which depends on the medium.► For remote controll electrical, pneumatic and hydraulic actuators can be installed.

Double Block & Bleed Valve ApplicationsDouble Block & Bleed expanding plug Valves are often used in the following applications:► Fiscal metering systems for gas and oil► Ship and truck loading services► Tank storage► Transport pipeline services► Clean hydrocarbon services► Aviation fuel services► MTBE services

HOW IT WORKS

Opening and Closing Sequence DBBV

1. OpenValve fully open. Seating slips are protected from flow path.

2. Start to closePlug is rotating. There is no contact between body and seating slips.

3. ExpandingPlug / slips have rotated 90°. Plug starts expanding slips. Slips only move perpendicular to body seats. Plug / slip assembly is kept centred in body by top and bottom bushings.

4. Double Block and BleedValve seated.Resilient seals have been compressed. Resilient seals cannot be damaged by operator over-torque. Double block and bleed function can be tested by opening the bleed valve.

5. Start to OpenValve starts opening.Plug moving up, retracting slips from the body seats. Strong dovetail and stems retract the slips. Plug is kept centred in body by top and bottom bushings.

6. Slips retractedSlips have been retracted prior to rotation.(Further workings as figure 1 and 2 in reversed order).

BLEED SYSTEMS

BLEED SYSTEMS FOR DBBV

Automatic Body Bleed (ABB)

The Control Seal Double Block and Bleed

Valve automatic body bleed is actuated when the valve is closed. As an option the isolating valve can be provided with ‘lock open’ to avoid any human error.Caution: When the Double Block and Bleed Valve comes to its closed position, a cam opens the Automatic Bleed Valve allowing fluid to escape. As the valve reaches its fully closed position, the spurting liquid should cease, showing positive verification of double seating. A proper drain system is required as spilled liquid could be hazardous.

Thermal Relief Upstream with Gauge (TRU-G)

To avoid body pressure due to thermal

expansion, a relief valve with gauge can be provided. This means no emission to the atmosphere and no sump system is required. Relief always set on 25 psi.

With this system on the Control Seal Double

Block and Bleed Valve, the thermal relief valve releases the overpressure from thebody cavity which may be caused by thermal expansion. The system releases from the body cavity to the upstream side of the valve.

Thermal Relief Upstream (TRU)

Manual Bleed Valve with Gauge (MVB-G)

A manual bleed valve connected with gauge

can be provided when emission is undesirable. The gauge will indicate the cavity pressure and the seal tightness.Note: Body pressure can be increased due to thermal effects, which can indicate false leakage.

Manual Bleed & Thermal Relief (MBTR)

This principle is the same as that of the TRU,

however with the possibility to check the integ-rity of the Double Block and Bleed Valve manually.Note: The relief valve is set to open at 25 psi on all valves regardless of their working pres-sure. With the Control Seal DoubleBlock and Bleed Valve closed, the relief valve will open at 25 psi above upstream pressure. This system functions only when the Control Seal DBBV is closed and the isolation valve is open.Caution: All automated Control Seal Double Block and Bleed Valves require some form of body pressure relief (TRU / MBTR / ABB / MBV-G / TRU-G), otherwise the valve may be difficult to open or may stick in closed position.

Bleed valve for manual operation. The Control

Seal Double Block and Bleed Valve must always be bleeded in closed position. The MBV is the most simple bleed system.
