MS Type Check Valve

MS Type Check Valve

MS check valve metal-to-metal seals are suitable for high-pressure / high-temperature environments where elastic seals cannot be used. MS check valve is suitable for high-pressure mud throttle manifold and high-pressure production tree injection and kill lines.

"MS" check valves can be used with oil, gas, water, or drilling fluids and can be used at all temperatures, material categories, and product specification levels (PSL) specified by API 6A. 

It has a standard pressure rating from 3000psi to 20000psi and an inner diameter from 1-13/16" to 4-1/16".

Design Features and Benefits

Metal to metal seal-metal to metal seal is an ideal choice for chemical fluid and well fluid contact. 

The sealing area and extreme temperature are a factor. 

Streamlined seat-streamlined seat area reduces turbulence and improves valve body life. 

Low maintenance-MS check valves have no lubricated parts and do not require routine maintenance. 

MS check valves meet API 6a end-to-end measurement requirements.
