Product Description

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.
