  • MK-GT

The MK-GT series of three-way control valves with sleeve guidance feature balanced or unbalanced valve cores and sleeve guidance. They can be used for regulating and on-off control of various fluids and are available in the following structures:

MK-GT-C (Balanced) - Suitable for general flow combination (fluid mixing) and flow division (fluid dispersion) conditions. Standard design and high-temperature resistant design are available.

MK-GT-S (Unbalanced) - Suitable for general river conditions.When this structure is used in flow division conditions, it is only recommended for on-off applications.

    Three-way flow division valves divide one fluid stream into two fluid streams,and three-way flow combination valves combine two fluid streams into one fluid stream. The MK-GT series valves are suitable for a variety of applications, including sulfide and chloride stress cracking environments commonly found in the oil and gas production industry.

  • Quick replacement of valve internals

    Standard quick-change valve internals facilitate on-site maintenance. Even if the valve is on the pipeline, all valve internals can be easily removed from the valve body.

  • Valve core stability

    The robust and durable valve cage guide provides excellent valve core stability, reducing vibration and mechanical noise.

  • Long service life of valve internals

    The valve internals made of hardened materials have excellent wear resistance.

  • The wall thickness of the valve body is in accordance with ASME B16.34-2013. Each valve body cavity is optimized through 3D modeling and CFD simulation to ensure fluid stability.

  • The valve body and the upper valve cover are fastened together as a whole by double-endedstuds, and the design complies with ASME Ⅷ.

  • The valve body structure allows the material to comply with NACE 0175-2003.
