Oilfield Downhole Check Valve For API ESP Equipment 5000psi Flow Control
Oilfield Downhole Check Valve 2 7/8" For API ESP Equipment
The check valve is installed about two to three joints above the ESP pump to maintain a full liquid column in the tubing string during equipment shut down period. The check valve is designed and used to prevent backflow through a pump, which uses a seat and plunger to block downward flow in the tubing string.. The check valve is a shuttle type poppet valve arrangement with a spring return. In installation without a check valve, it must be ensured that the tubing string completely drains back to the well through the pump before the motor is started again
