ADV™ (Automatic Diverter Valve)

The ADV™ is a patented automatic check and drain valve that operates immediately on pump start up / shut down. Prior to pump start up there is natural flow past the ESP. On ESP switch-on the ADV™ automatically operates to close ports to the annulus and pumped production commences to surface. Upon ESP trip / shut down, fluid and solids in the tubing string exhaust into the annulus. Communication to the ESP is blocked preventing solids entering the ESP. When the ESP is restarted the ADV™ automatically operates to close ports to annulus and normal production resumes.

This versatile valve can be used to protect the pump from fall back of solids or allow flow from the annulus to the production tubing. A common cause of ESP failures is when solids in the tubing string above the pump are allowed to fall back into the pump after the ESP has been switched off (either manually or automatically). Solids that settle in the top stages of the ESP often plug the pump.

Quite simply, the ADV™ increases ESP run life.
