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.
Applications
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.
Application
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.
