Tools Application
OTF The coiled tubing back pressure valve is a component of the coiled tubing string component that provides a circulation path against a predetermined back pressure. It is ideal for jobs where the hydrostatic pressure in the coiled tubing must be higher than the pressure in the annulus areas.
The design of the coiled tubing back pressure valve allows on-site determination of the back pressure to be set at the surface. This is achieved by using different ball diameters to increase/decrease the piston area and the pressure required to open the valve.
Design feature & Benefit
- Metal-to-metal sealing
- Ball and cage design protects components from wash out
- Site adjustable settings
- Simple design allows for easy maintenance
