Product Description

Product Description

Mud Pump Valve & Seat are made of premium alloy steel through one-piece forging and carburizing treatment processes, thereby ensuring high intensity. In addition, the precise calculation is performed and CNC machining is conducted for the dimensional matching of the valve seat and valve body working angles to enhance the service life of the valve body and valve seat. Our valve products are able to work smoothly in normal mining and digging conditions for over 400 hours.

Valve is a bonded urethane valve that will hold up to the most hostile drilling environment and withstand high pressure, high temperature and high solids superior performance, long run life, excellent abrasion resistance and sealing surface coupled with the highest rated chemically resistant urethane make an excellent choice for any drilling application.

Unique urethane bonding anchor
Reliable with the highest quality control
High Temperature Urethane
Excellent extrusion and abrasion resistance
The strongest urethane bond of any valve for increased service life and a stronger seal
Excellent chemical resistance
Greater valve life
7500+ psi rated
300°F rated urethane
Precision machined
Carburized and heat treated
Full open seat
API-6 - 8 available
