Finished ST ball and seat
Half-finished ST ball and seat
The valve ball and seat is a important part of the oil field mining pump, its using directly decides the service life of pump.According to the corrosion characteristics of oil, oil Wells can provide different material
We can produce the API 11AX ball and seat in materials stainless steel AISI440C and hard alloy (tungsten carbide and STELLITE), with advantages of high hardness, wear resistance, corrosion resistance.
Each of our ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.

Application:
Valve balls and seats are used in the manufacture of valves of submersible sucker-rod pumps, a check valve used for oil and gas production. Valve balls and seats are the most critical parts of the pump, because it is subject to the greatest chemical and mechanical stress.
