Tungsten Carbide Balls for Valve         
 
Valve ball and valve seat is widely used in petroleum industry, especially for oil well pump, such as sucker rod pump.Tungsten carbide balls for valves are widely used in where extreme hardness and wear resistance is  Required. Such as: Bearings, ball screws, valves and flow meters pen,spraying machines, pump, machinery parts, oil, hydrochloric Zcid lab,hardness measuring instrument, and so high-end industry. Your drawing is welcomed.The YG11 tungsten carbide ball with a high hardness and wear resistance, it's toughness is better than YG6 alloy ball and has good anti-vibration shock engaged in the performance, suitable for production of strong shock and vibration components.
