Providing a circulation path against a predetermined backpressure, our backpressure valve is ideally suited for operations in which the hydrostatic pressure within the coiled tubing needs to be higher than the pressure in the annulus areas.
The design of the coiled tubing backpressure valve allows for an on-site determination of backpressure to be set at surface. This is achieved with the use of different ball diameters to increase/decrease the piston area and pressure required to open the valve.
Coiled tubing backpressure valves are not ideally suited for cementing or abrasive fluids.
For calibrated fluid delivery valves, please see coiled tubing cement valves.
