Our ball-and-seat valves are designed and manufactured according to API 11AX Specification for Subsurface Sucker Rod Pumps and Fittings (current edition). Each ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.
Available materials and qualities to be used in assemblies of the same or combined materials are as follows:
1. Stainless Steel: API symbol A1
2. Cobalt Alloy: API symbol B2
3. Tungsten Carbide: API symbol C1
4. Nickel Carbide: API symbol C2
5. Titanium Carbide: API symbol C3
main material for reference:
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.
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.
They are used with compatible cemented carbide valve seats.
1. High strength, high wear resistance,
2.high precision, high temperature resistant,
4.Stainless Steel, Tungsten Carbide, Titanium Carbide, Cobalt Alloy are the main material.
