In-Riser Revolution Valve

The in-riser Revolution shear-seal valve is designed to be incorporated in a subsea landing string system. We have delivered 6-5/8” 10K psi and 6-3/8” 15K psi versions, plus a 4-1/8” 10K valve designed for slimline well access. Interventek has also developed the world’s first API-17G qualified, 5-1/8” 20K in-riser shear-seal valve. This ultra-high pressure, high temperature (HPHT) version is able to withstand working pressures of 20,000psi and temperatures up to 350 degrees Fahrenheit.

In-Riser Revolution Valve

The compact nature of the Revolution valve and its actuator components is extremely beneficial for in-riser applications. A short valve is more easily accommodated to sit below drilling BOPs which have irregular shear ram spacing and can often be restrictive.

The compact internals leave substantial material available in the body to be utilised for preloaded end connections, such as a flange. These connections are mechanically superior to non-preloaded connections and extremely desirable where cyclic loading is possible.
