Check Valve  
Check Valves

    
Check valves are recommended for use in the tubing string for ESP system to keep the discharge-tubing full of fluid when the pump is off. The check valve allows for a full column of fluid/head for the pump to restart against, thereby; eliminating the possibility of damage to the pumping system that may be attributed to insufficient head. It will also eliminate fluid from flushing back through the pump enabling a quicker restart. The check valve is run generally two or three joints above the pump. If the check valve is not installed, the pump should not be started until the fluid column has had a chance to equalize, eliminating the chance for a twisted shaft in the pump, or a burned cable or motor. (A minimum of thirty minutes is recommended.) When a check valve is used, it is recommendedtt to install a drain valve.
