seal is obtained in all positions of contact.
For sealing of valves of oil pumps in petroleum industry's sand
containing wells, viscous oil wells, sea oil wells,high pressure
sulfur resistant oil wells, compatible Cemented Carbide valve
seats, etc.Various grades for cemented carbide balls/pellets can be
supplied according to customer's drawings.The surface
finish,tolerance class and tolerances of dimensions have
respectively reached the standards of the machine industry.
