API 6D THROUGH CONDUIT PARALLEL EXPANDING GATE VALVE standard features
Standard Features
and Benefits
1: 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.
Figure A
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
Fi gure-C
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.
Figure C
This has now formed a tight seal or “double block”
on both sides of the expanding gate.
Figure-C
Fi gure-C
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
cavity to remove debris / take a sample of the
medium / test the sealing integrity of the seats.
3. 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.

Operation Principles
Figure E
Figure F
Figure F
Figure
F
Figure G
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.

Gate Centralizer Operation Principles
Figure H
Figure I
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

Body Cavity Pressure Relief
Figure K
K
Figure
Figure L
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)
