YN11 Cemented Tungsten Carbide Wear Parts High Temperature Resistant

WC Tungsten Carbide Valve Seats / Tungsten Carbide Valve Core

Description

Precision machined carbide balls and valve seats

High strength, high wear resistance, high precision, high temperature resistant, corrosion resistant.

They 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.

The surface finish, tolerance class and tolerances of dimensions have respectively reached the standards of the machine industry: G5, G10, G16, G40 and G100 of JB/T 9145-1999.

Precision machined cemented carbide balls of other grades and specifications are also available based on customers’ demands.

Compatible high precision valve seats can also be made available.
