Product Description

Customiozed Casting Regulating Ball Valve Gate Valve Butterfly Valve Seat For Oil/Water

Tungsten carbide balls and valve seats have the compositions of tungsten carbide(WC) and Co or Ni or Mo additives. With high compression strength, excellent wear resistance and well shock and impact resistance, tungsten carbide balls and valve seats are widely supplied as ball-rolling element in bearing industry, pump valve spool for fluid seal, check valve for petroleum digger,industrial sprayers to regulate the flow of fertilizers or pesticides to crops.
Tungsten carbide balls can be also applied in a drastically different application, it can be employed as pen balls due to their inert chemical properties. Besides, in miniature flow control devices, such as medical instrumentation and ink-jet printing, tungsten carbide balls are also frequently used.
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.
Features of tungsten valve seat 
1. 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.
2. Various grades for cemented carbide balls/pellets can be supplied according to customer's drawings.
3. The surface finish, tolerance class and tolerances of dimensions have respectively reached the standards of the machine industry.
Tungsten carbide ball was widely used in precision tools drawing and punching,high precision bearings,high precision measuring instrument and appratus,water pump and brake pump,and various machinery sealing accessories part in high-tech industry.
Dia. 2, 5, 7, 8, 10, 12mm (or 5/8, 3/4, 15/16, 1-1/8, 1-1/4, 1-3/8, 1-1/16, 2-1/4") and more.
