PRODUCTS INTRODUCTION
The GEOTHERMAL EXPANDING GATE VALVE is an unidirectional manual operated valve with
non-rising or rising stem and parallel expanding gate and segment design. The parallel expanding
gate design provides a tight mechanical seal which is normally unaffected by pressure fluctuations
or variations. The gate assembly uses an angular gate face which is collapsed during travel. When
closed, a stop causes any further downward travel to force the faces of the gate assembly outward
to effect a positive line flow seal. When opened, a stop causes any further upward travel to force
bottom faces to expand and seal against the seats to isolate flow from the valve body cavity.
The stem is sealed by reinforced graphite packing and injectable packing. In an emergency,
injecting injectable packing into packing box would affect a temporary seal while the valve is under
pressure.
The expanding valve is designed, manufactured and tested in accordance with API Spec. 6A unless
otherwise specified.

PRODUCT VIEW AND FUNCTION
THREE OPERATION STATUS:
Fully Opened:
The segment is stopped by
contacting with the bonnet
stop. The gate continuous
moving up to expand the
segment and gate against
both seats to form a
positive mechanical seal,
no matter with or without
line pressure
Stroking Position:
When stroking to open or
closed position, the gate
and segment is held by
spring with no forced
contact in between closure
member (gate and
segment) against the
seats which minimize
friction during stroking.
Fully Closed:
The segment going down is
stopped by contact with the
bottom body. The gate
continuous moving down to
expand the segment and
gate against both seats to
form a positive mechanical
seal, no matter with or
without line pressure.

Operating & Service Manual 1OPS-806 Rev.02
1 General Information
The expanding gate valve is a unidirectional non-rising stem manual operated valve incorporating an
expanding gate and seats design. The parallel expanding gate design provides a tight mechanical seal
which is normally unaffected by pressure fluctuations or variations. The gate assembly uses an wedge
face which is collapsed during travel. When closed, a stop causes any further downward travel to force
the faces of the gate assembly outward to effect a positive line flow seal. When opened, a stop causes
any further upward travel to force bottom faces to expand and seal against the seats to isolate flow from
the valve body cavity.
The bonnet is bolted to the valve body and pressure integrity is achieved by means of a metal ring gasket.
Pressure energized stem packing set are used to isolate pressure in the valve cavity.
The bearing spacer is sandwiched by thrust bearing assembly to provide a sturdy low operating torque
gate valve.
The bonnet is equipped with an injection fitting for packing injection and a standard grease zerk (1/8”) for
lubrication of the stem bearing assembly. The body is equipped with two 1/2” vent/grease fittings which
can be also used for body lubrication pressure relief.
The gate valve is not designed to be used as a throttle valve.
ALL OPERATORS AND MAINTENANCE PERSONNEL SHOULD BE THOROUGHLY TRAINED IN THE
SAFE OPERATION, MAINTENANCE, AND INSPECTION OF THIS EQUIPMENT.

Operating & Service Manual 2OPS-806 Rev.02
2 Installation
2.1 Unpacking
a) The valve is shipped in full open position with flange end protectors installed. This is to
preclude debris from falling into valve cavity.
b) Remove flange protectors and thoroughly inspect interior of valve and end connections for
damage or foreign material.
c) Install loose items such as hand wheels, etc. if separated from valve assembly.
2.2 Handling
Proper lifting equipment should be provided to handle the valve.
CAUTION:
Do not use hand-wheels of the valve to lift the valve. Avoid damaging the end connection
faces and fittings during handling.
2.3 Installation
a) Install the valve in the open position with the preferred
upstream pressure side. The preferred upstream pressure
side is the right hand flange when looking at the lettered and
fitting side of the body. This flange is painted yellow as shown.
b) Flanged end valves should be installed using the appropriate
gasket (not supplied) and conventional flange installation
procedures.
c) Prior to operating the valve from the open position, the conduit
should be thoroughly flushed to prevent foreign material from
damaging sealing surfaces.
Assembly Drawing
Assembly drawing, see next page

Operating & Service Manual 3OPS-806 Rev.02

Operating & Service Manual 4OPS-806 Rev.02
3 Operation
Turn the hand-wheel clockwise to CLOSE the valve until it becomes tight. Tighten securely to mechanically
energize the seal. DO NOT BACK OFF THE HAND-WHEEL.
Turn the hand-wheel counter-clockwise to OPEN the valve until segment is stopped by the bonnet.
If necessary, with the valve fully CLOSED, cavity pressure can be relieved through the body vent fitting.
WARNING:
Always wear approved safety gear and face away from the vents when relieving pressure from the
valve.
4 Maintenance
Periodic maintenance is required for the expanding gate valves to promote trouble-free service and long
life. Visually inspect every six months for any leakage, abnormal sound and bolt loosened, see Trouble
Shooting for temporary solution to problems. Operate the valve once a month where practicable. A full
open and close cycle is preferable, operate a partial cycle as a minimum. Stem bearing lubricated once a
year.
4.1 Valve Cavity Lubrication
The valve cavity to be lubricated on a regular basis
to ensure continuous smooth operation of the
valve. Generally, lubrication may be carried out
after valve draining. Whenever possible lubrication
should only be done after the valve is isolated from
the pressure. Approximately one pound of grease
per inch of valve bore size will sufficiently lubricate
the valve body. It is not necessary to completely fill
the valve body.
Lubrication Procedure with Isolated Line
Pressure
a) Fully close or open valve, remove cap on grease fitting located on the valve body and install pressure
releasing tool to one fitting and grease pump to the other.
b) Use pressure releasing tool to bleed off any pressure trapped in the valve cavity and leave stringer in
