Automatic directional valve-BYADV001
Description
The BYADV is an automatic check & drain valve that operates immediately on pump start up / shut down. 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. When the ESP is restarted, any of the following problems can result:
- no flow condition
- severe wear of stages
- electrical stresses
- mechanical stresses
- twisted shaft
Installing an BYADV avoids these problems as ports to the annulus are opened automatically to purge the tubing string upon ESP shut down, whilst simultaneously shutting off communication to the ESP. When the fluid level in the tubing reaches the static fluid level in the annulus, solids that are held in suspension, continue to fall out through the ports. When the operator restarts the ESP, the ports are automatically closed as production is resumed.
