PILOT OPERATED GAS LIFT VALVE

PARVEEN’S Conventional Pilot Valve (1" & 1-1/2" OD) and Retrivable Pilot Valve (1" OD) consist of a pilot section and a power section.

This valve utilizes a pilot section to activate a power section.

A sealed chamber, including a multiply monel bellow, contain a nitrogen pressure charge over a dampening fluid which provides the closing force necessary to maintain the pilot section in a normally closed position and an inconel spring provides the force necessary to maintain the power section normally in a closed position.

Features

Pilot operated valves are used primarily for intermittent gas lift where large, instantaneous injection gas volumes between opening and closing injection gas pressure are desired.

The pilot valve can also be used where intermittent lift is required but injection gas must be controlled by a choke to prevent surface gas system pressure fluctuations.
