7 3/8-10K Coil Cutting Valves

Worldwide Oilfield Machine (WOM) has developed a 7-3/8” – 10K Coil Cutting Valve based on gate valve concept to cut and seal coil tubing. The Coil cutting valve is equipped with 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.
