Tungsten carbide is widely used onTungsten Carbide Valve Stem and Tungsten Carbide Seat ,carbide bushings are installed in the valve stem cap trap in order to reduce the valve leakage, sealing bearing sleeves as protecting parts to undertake wear between the bearing and the shaft seat to avoid the friction between the shaft and the hole increases and so on.
Tungsten Carbide Valve Stem and Tungsten Carbide Seat can withstand prolonged load with high chemical stability, it is resistance to alkali, alcohol,hydrocarbons, acid, oil, detergent, water (sea water), and they are absolutly non-toxic, tasteless, non-rust characteristics,which widely used in petrochemical industry for Submerged Oil Pump, slurry pump, water pump, Centrifugal Pump,etc.
