Retrievable Production - Pressure Operated Gas Lift Valves PR-5 |
|
DESCRIPTION
ACT wireline retrievable production pressure operated GLV' s are used for continuous
flow gas lift production. A nitrogen charged multiply monel bellow provides the force
necessary to maintain valve in a normally closed position.T his valve contain integral
reverse flow check valve.
Port sizes available are 3/16", 1/4" & 5/16"
OPERATION
Production fluid enters the valve and acts on the effective bellow area. The production
pressure necessary to compress the bellow is controlled by precharged nitrogen
pressure. When production pressure overcomes the precharged nitrogen pressure in the
bellow, the bellow is compressed and lifts the stem tip off the seat. Injection gas flows
through the seat, past the reverse flow check valve and into the production conduit.
