INTRODUCTION to API 6D PIPELINE GATE VALVES
Williams Valve manufacturers API 6D Pipeline Gate Valves in both Slab and Expanding Wedge designs. Both designs are full bore, bi-directional, capable of double block and bleed sealing and are ideal for pipeline pigging operations. These valves are top entry design with floating seats, and thus both are serviceable while installed in the flow line. Manufactured to API-6D requirements Williams Valves also carry the API 6D monogram, audited and issued by the American Petroleum Institute.
Comparing the Slab and Expanding Gate Valve
Slab and Expanding Gate Valves are both widely used, particularly in the Midstream Pipeline and Terminal Storage Industry. The question often arises, which is the better valve? That of course depends largely on the application.
The Slab Gate Valve is generally considered the work-horse pipeline valve. When reliability, ease of maintenance and cost are the primary factors a Williams Slab Gate Valve is the optimal choice. The simplest of all piggable pipeline valves this design has the fewest moving parts. The large seat to seal area tolerates minor scratches better than ball valves and no external piping or relief is required to overcome internal pressure differential due to thermal expansion. The valve is most often used as a pipeline block valve for applications requiring a full bore and API-6D Double Block & Bleed sealing. The Slab Gate design is preferred for use with actuation.
The Expanding Gate Valve manufactured by Williams, is a premium engineered product for critical applications. Like a Slab Gate this valve seals by the internal pipeline pressure but a simultaneous second seal is created by the mechanical force of the expanding gate against the floating seats. This dual sealing provides a higher degree of security in situations where extreme pressure differential is a factor. It is often the preferred valve for pigging operations where the gate is the only pressure barrier to the atmosphere. Unlike the Slab design, the Expanding Gate Valve is capable of true Double Isolation & Bleed as well as Double Block and Bleed. The Double Isolation is enhanced by the mechanical gate to seat contact which provides a positive low pressure seal. The mechanical contact between gate and seats also help prevent debris or solids in the flow-line from entering the body cavity. Manufacturing an Expanding Gate valve is complex with more moving parts than a Slab Gate. Low torque manual operation is preferred.

SLAB VALVE GATE DESIGN FEATURES
When the valve is open the seat faces are outside the flow protected from the erosive action of the media or damage by pigs or scrapers. The design of the valve seat combined with precision machining results in a bi-directional bubble-tight seal at both low pressure and full rated working pressure. The seat design provides automatic relief of internal body pressure and the valve will double-block and bleed in accordance with API-6D. The precise machining of the slab and seats leaves little space in the bore minimizing pipeline turbulence. Williams Slab Gate Valves are available in a variety of body and trim materials to suit various applications.
1. Floating metal seat rings (Fig. B) are equipped with soft face seals (1) and are held in constant contact with the gate by energized O-rings (2) located behind the metal seat ring. This ensures a seat to gate seal requiring less handwheel torque than spring-loaded seats
2. With application of line pressure against the O-ring (3) on the O.D. of the upstream seat, both the seat and gate float against the downstream seat thus ensuring a positive bubble-tight seal
3. With upstream and downstream floating seats, Double Block & Bleed in accordance with API-6D can be achieved. Should internal body pressure exceed line pressure, the floating seat will back-off the gate until excess pressure is relieved as indicated by the arrow (Fig. A)
4. The full-bore through conduit gate valve is fully piggable without danger of damage to the valve seats. Fittings are provided for either seat lubrication or emergency seat sealant injection (Fig. C)
5. The stem seal packing box is provided with fittings for emergency sealant injection (Fig. D). Alternative stem seal designs are available to meet customer requirements
6. In the event of a fire and damage to the soft O-ring and face seals, metal to metal contact between the gate, the downstream seat, and the body provide a secondary seal
7. After isolation of the valve and relief of any internal pressure, the top entry bonnet may be removed and the seats and/or gate replaced with the valve installed in the flow line

EXPANDING GATE VALVE DESIGN FEATURES:
1. The Williams Expanding Gate Valve provides a positive mechanical seal to ensure a bubble-tight shut-off at both high and low pressure. The mechanical seal is normally unaffected by vibration or variation in line pressure. The valve seals bi-directionally and will achieve Double Block & Bleed per API-6D requirements.
2. Floating seats have a soft face resilient seal. Various sealing materials are available to meet customer requirements. Top entry bonnet design allows for inline maintenance and replacement of the resilient seat
3. The full-bore through conduit gate valve is fully PIG-able without damage to the valve seats
4. Fire safe design offers extended protection by a secondary metal to metal seat
5. The stem seal packing box is provided with fittings for emergency sealant injection if needed (Fig. D - Page 4) alternative stem seal designs to that shown are available to meet customer requirements
6. After isolation of the valve and relief of any internal pressure, the top entry bonnet may be removed and the seats and/or gate assembly replaced with the valve installed in the flow line
EXPANDING GATE MECHANICS:
Williams Expanding Gate Valve assembly consists of a Gate and Segment. Attached to the Operating Stem the Gate has angles machined on one surface with matching angles machined on the Segment (Fig E.). While traveling up or down, a Centralizer Mechanism hold the gate/segment assembly in a "collapsed" position with the mating inclined surfaces in full contact with one another (Fig. H – Page 9).
9
EXPANDING GATE VALVE FUNCTIONING PRINCIPALS
Fully Closed Valve:
When the valve is operated to the fully closed position, the Operating Stem pushes the collapsed gate/segment assembly downward until a Stop on the Segment contacts the valve body just above the upstream seat (Fig. E – Page 8) preventing further downward movement. At the same time the Centralizing Mechanism shifts and ceases to prevent the Gate and Segment from moving horizontally (Fig. I).
The Gate continues down and contact between the upper mating gate and segment angles results in both moving horizontally into contact with the respective valve Seat (Fig. E – Page 8). This "wedging" action of the Gate and the Segment against each seat results in a positive upstream and downstream mechanical seal.
Opening the Valve:
When opening the valve, the Operating Stem pulls upward on the Gate and the "wedging" force on the angled surfaces is removed allowing the Segment to move horizontally back into full contact with the Gate (Fig. F – Page 8). Again, the Centralizer Mechanism holds the Gate and the Segment in a "collapsed" position (Fig. H).
Fully Open Valve
As the "collapsed" gate/segment assembly moves upward, the Stop on the Segment contacts the valve bonnet and stops travel of the Segment (Fig. G – Page 8). Again the Centralizing Mechanism shifts and ceases to prevent horizontal movement of the Gate and Segment (Fig. J). Contact between the lower angles results in the Gate and the Segment wedging against the respective valve Seat (Fig. G – Page 8). Flow into the body cavity is prevented and fluid flow through the valve occurs with minimum turbulence.
10
PRIMARY & SEONDARY SEATING:
Williams expanding gate assembly maintains positive mechanical contact and seals against the upstream and downstream seats simultaneously. Each seat contains a primary resilient seal (normally PTFE) press-fitted into the metal seat ring. In the event of a fire and damage to the primary seals metal to metal contact between the gate assembly, the seats, and the body provide a secondary seal. Injection fittings are also present for emergency sealing of the pipeline (Fig. C – Page 4).
THERMAL BODY CAVITY RELIEF
In the event of variations in temperature, Williams Expanding Gate Valves are designed with options for relief of internal body pressure due to thermal expansion. The thermal relief configuration is installed according to the customer’s requirements.
1. An upstream bypass system with a needle valve and a check valve can be fitted (Fig. P). This provides for relief of excessive body pressure to the upstream flow conduit. The needle valve must be kept open while the valve is in service, and can be closed to test and service the check valve.
2. Relief of internal body pressure can also be provided by an external pressure relief valve where permitted (Fig. Q).
