Tungsten Carbide Valve Ball & Seats Oilfield Pump Parts
Tungsten carbide valve Balls and seats
The oilfiedl pump parts tungsten carbide valve ball and seats consist of complex carbides in an alloy matrix. They are resistant to wear, galling, and corrosion and retain these properties at high temperatures. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix.
