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.

 

Available Modles

Bleeder Balves

The bleeder Valve is normally installed one joint above the check valve. The Bleeder Valve or Drain Valve has a small drain plug in it, and dropped a bar inside the tubing string will break it and allow the tubing to drain well fluid to the tubing and casting anulus.

Available Models

Drain and Fill Valve (3/8" x 5/8")

The Drain and Fill Valve is used for fill and drain motor oil in ESP motor and seal section when making installation and pulling out. Monel K500 and Monel R405 are the typical materials used for ESP submersible pumping systems.
