Technical Data Sheet Category Catalog

 

The Pump-Off Check Valve is run on the bottom end of the coiled tubing during work-overs or completion operations. The Check Valve provides a one-way flow for clean-out fluids such as N2 or CO2 to be pumped down the coil string. When used on completion installations, the valve eliminates an extra coiled tubing clean-out trip by unloading or cleaning to well bottom, prior to hang-off operations. When flow up the tubing is required, a ball is dropped and the coil string is pressured to shear release the Pump-Off Check Valve from the coiled tubing.
