EPmag.com | September 2017 | 9 VALVE TECHBOOK: TECHNOLOGY valve can withstand working pressures of 20,000 psi (20K) and temperatures of 350 F (177 C) for in-riser landing string systems. The Revolution Valve was designed for emerging HP/HT and deepwater well environments, particularly in the Gulf of Mexico, and is believed to be the first of its kind. "The 20,000-psi valve was developed from our 15,000-psi form with very compact internal com- ponents and external rotary actuators. The simplicity of design makes it very eligible for fulfilling other configurations," said Gavin Cowie, managing director, Interventek. The 20K in-riser valve is able to cut slickline, braided cable and coiled tubing up to 2 in. in diameter with wall thickness of 0.203 in. and 148-ksi tensile strength. The bore size is up to 5.125 in. "The valve is uti- lized during installa- tion and workover of wells completed with horizontal type christ - mas trees. The unique design is comprised of two elements. The first is a sealing f lapper component, which is pivotally mounted to a second component— the structural saddle that allows the back and forth rotation," he explained. "The saddle delivers the cutting forces and incorporates a hard- ened cutting insert. The primary sealing bound- ary is elastomer-free, relying instead on h i g h - s p e c i f i c a t i o n , resilient seals to con- tain produced fluids. It uses metallic sealing for the temperature piece of the system. The seals, like all the valve compo- nents, can be accessed for inspection or mainte- nance," he added. "Conventional ball valves were never originally designed to be cutting tools. The same leading edge of the surface that is required to create a seal is now used as a cutting edge, so is vulnerable to damage and may not seal effectively," he said.
