Product Description

V11-225 stellite  alloy valve balls and seats

Both are mainly used for the sealing of valves of oil pumps in petroleum industry's sand containing wells, 
viscous oil wells, sea oil wells and high pressure sulfur resistant oil wells, etc. 
 
They are used with compatible cemented carbide valve seats and valve balls.
The valve balls and valve seats are main components and parts of the sucker rod pump.
Materials: Stainless Steel, Tungsten Carbide, Titanium Carbide, Cobalt Alloy
