Standard Features and Benefits1. Seats / Fire-Safe Design

(See Figure A)

Depending upon the service of the

valve, the seats can be supplied

with soft seat inserts / hard face

deposited metal seats.

The line pressure / springs /

energized O-rings, assists the single

piston effect designed seats for

high / low pressure sealing against

the slab gate face, ensuring that a

tight seal is formed. The soft seats

and the seat pockets have been

designed to be fire-safe.

During a fire, the soft seats can be

destroyed. As the seats are being

slowly burnt, the upstream pressure

forces the slab gate against the

downstream seat. The downstream

seat is thereby forced against

the back of the seat pocket. The

downstream seat is now forming a

metal-to-metal seal with the back

of the seat pocket face. When the

soft seats have been fully burnt, the

metal face of the seat now forms

a metal-to-metal seal with the slab

gate. Metal seated seats are fire-

safe by design.

2: Double Block and Bleed

(See Figure A)

The double block feature is the result

of the two seats sealing against the

slab gate, with the valve in the fully

closed position, whether the line is

under pressure or not.

When there is no pressure on either

side of the seats, the springs /

energized O-rings force the seats to

form a tight seal on the upstream /

downstream sides of the slab gate.

When there is pressure in the line,

the upstream pressure forces the

slab gate against the downstream

seat, whilst also forcing the

upstream seat against the slab gate,

due to the single piston effect design

of the seats.

This has now formed a tight seal or

“double block” on both sides of the

slab gate.

With the slab gate now tightly sealed

on both sides, the vent / drain

plug in the body can be released

which will “bleed” the body cavity

of pressure. This feature allows the

draining of the cavity to remove

debris / take a sample of the

medium / test the sealing integrity of

the seats.

3: Automatic Cavity Relief

(See Figure B)

Should the pressure in the body

cavity exceed the line pressure, due

to thermal expansion caused by

an internal / external heat source,

the greater cavity pressure will

push the seat off the slab gate

face allowing the excess cavity

pressure to be vented into the line.

This feature ensures that there is

pressure equilibrium between the

line and body cavity, which prevents

the body material becoming over-

stressed.

4: Seat Sealant Injection

(See Figure C & D)

Due to possible damage of the seats

by debris in the line / stem O-ring

failure due to a prolonged service,

there can be leakage from these

areas. To extend the service life

of the valve until the valve can be

removed from the line for repair, a

sealant can be injected through the

seat / stem injection fittings.

Standard Features and Benefits1: Seats/Fire-Safe Design (See Figure A)

Depending upon the service of the valve, the seats

can be supplied with soft seat inserts / hard face

deposited metal seats.

As the sealing action of the valve is mechanically

activated, line pressure is not required to force the

seats against the expanding gate. Therefore, the

seats are of a very basic, but rugged design.

The soft seats and the seat pockets have been

designed to be fire-safe.

The sealing action of the fire-safe design is the

same as that of the slab gate valve.

Metal seated seats are fire-safe by design.

2. Double Block and Bleed (See Figure A)

The double block feature is the result of the two seats

sealing against the expanding gate, with the valve

in the fully closed position, whether the line is under

pressure or not.

When there is no pressure on either side of the

seats, the springs / energized O-rings force

the seats to form a tight seal on the upstream /

downstream sides of the expanding gate.

When there is pressure in the line, the upstream

pressure forces the expanding gate against the

downstream seat, whilst also forcing the upstream

seat against the expanding gate, due to the

single piston effect design of the seats.

This has now formed a tight seal or “double block”

on both sides of the expanding gate.

With the expanding gate now tightly sealed on

both sides, the vent / drain plug in the body can

be released which will “bleed” the body cavity of

pressure. This feature allows the draining of the

Due to possible damage of the seats by debris in

the line / stem O-ring failure due to a prolonged

service, there can be leakage from these areas. To

extend the service life of the valve until the valve can

Closed Position: Gate Assembly Fully Expanded (See Figure E)

As the gate and segment assembly are approaching the closed position, the stopper on the segment

has contacted with the lower body stop, which prevents the segment from travelling any further. As

the hand wheel is turned further, the main gate is forced down and against the wedge angle of the

segment. This action expands the gate and segment assembly against the seats to form a tight seal.

Mid Travel Position: Gate Assembly Fully Retracted (See Figure F)

As the hand wheel is turned to open the valve, the gate travels up and away from the wedge angle of

the segment. This action retracts the gate and segment assembly sealing force from the seats, which

allows the assembly to travel freely between the seats.

From the fully open to the fully closed positions, a gate centralizing mechanism holds the gate and

segment assembly in the fully retracted position, to ensure that the assembly does not wedge itself

between the seats.

Open Position: Gate Assembly Fully Expanded (See Figure G)

As the gate and segment assembly are approaching the open position, the stopper on the segment

has contacted with the upper body stop, which prevents the segment from travelling any further.

As the hand wheel is turned further, the main gate is forced up and against the wedge angle of the

segment. This action expands the gate and segment assembly against the seats to form a tight seal

to isolate the flow from the body cavity.

At this position, the bore holes of the gate and segment are aligned exactly with the valve bore.

Operation Principles


15

The main purpose of the gate centralizer is

to maintain the gate and segment assembly

in the fully retracted position, during the

travel from open to close, to prevent any

wedging action between the assembly and

the seats (See Figure H)

However, the gate centralizer allows the

gate and segment assembly to expand at

the final moment.

During the travel from open to close, the

gate centralizer is maintained in a parallel

position with the seats by the skirt plates,

which are positioned either side of the seats

(See Figure I)

As the gate and segment assembly are

nearing the fully open / closed positions,

the skirt plates allow the gate centralizer

to tilt, which allows the gate and segment

assembly to expand.

The skirt plates also assist in aligning the

gate and segment assembly with the seats

(See Figure J)


Figure H Figure I

Figure J

Gate Centralizer Operation Principles

Figure K Figure L

Due to the design of the expanding gate and seats to form a tight seal, any excess pressure

build-up in the body cavity can’t be self-relieved, as in the slab gate design.

To relieve this body cavity pressure, 2 types of a pressure relief system can be provided on the outside

of the valve body.

The standard type consists of 2 needle valves, a check valve, tubing and fittings. This system relieves

the body cavity pressure to the upstream side of the valve. During normal valve operation, the 2

needle valves must be kept open, so that the upstream line pressure can keep the check valve closed.

When the body cavity pressure exceeds the upstream line pressure, the check valve is

un-seated and the excess pressure is relieved upstream (See Figure K)

The other type of pressure relief system is a safety pressure relief valve fitted on the outside of the

valve body. A drilled and threaded hole connects the body cavity to the safety pressure relief valve.

The safety pressure relief valve is set to relieve pressure at 1.33 times the line pressure, or as per the

clients requirements (See Figure L)
