Pump-Off Check Valve
The Pump-Off Check Valve was developed primarily for the snubbing and workover industry. This tool allows for circulating sand and solids while tripping tubing in the hole under pressure. Upon landing tubing at surface, a ball is dropped and pumped down to the tool. This causes the aluminum insert locking mechanism to shear and release. Once released a full I.D. is left in the production tubing.
