6 3/8-15K Coil Cutting Valves

Based on gate valve technology to cut and seal coil tubing, our CCV is equipped with a horizontal, hydraulically-actuated single gate made to shear and seal coiled tubing and wire line of a given specification in the wellbore. A seal is made after the shearing, isolating the pressure/fluids from both upstream and downstream. The coil cutting valve is powered by accumulators and can be overridden via ROV manual over-ride.
