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.
