China Precision Cemented Carbide Seat
TC seat, tungsten carbide seat, tungsten carbide valve seat, gas lift valve seat.
We manufacture tungsten carbide valve seats for standard 1" Valves in port sizes from 1/8" to 3/8", standard 1 1/2" in port sizes from 1/8" to 1/2"; We also manufacture customized seats as per your specific drawings and material specifications.
These tungsten carbide valve seats are used for Conventional Gas Lift Valves, Wireline Retrievable (WLR) Injection Pressure Operated (IPO) Gas Lift Valves, various Oil Field Equipment, Oilfield Valves, oil pumps in petroleum industry's sand containing wells, viscous oil wells, sea oil wells and high pressure sulfur resistant oil wells, etc.
The feature of our valve seats: High strength, high wear resistance, high precision, high temperature resistant and high corrosion resistant.
API V11-225 valve balls and valve seat
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.
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.
