Description
V11-175 stainless steel API Valve Balls and Valve Seats
Description
Both 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.
1.Made by 100% original raw materials
2.Good abrasive resistance
3.After accurate grinding and polishing,the frictional factor of surface is very low.
4.Widely used in ball-bearing,seat valve, ball screws and flow meters.pen,spraying machines ,pump,machinery parts,oil,hydrochloric zcid lab,hardness measuring instrument,and so high-end industry.
5.Recommended grade: YG8,YG11,YG15,YS2T,YL10.2,other grade can be offered by customers' request.
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.Various grades for
cemented carbide balls/pellets can be supplied according to customer's drawings.The surface finish,
tolerance class and tolerances of dimensions have respectively reached the standards of the machine industry.
features:
1. High strength, high wear resistance,
2.high precision, high temperature resistant,
3.corrosion resistant.
4.Stainless Steel, Tungsten Carbide, Titanium Carbide, Cobalt Alloy are the main material.
