The valve ball and valve seat are important components of oilfield mining pumps, and their use directly determines the service life of the pump. Depending on the corrosive properties of the oil, oil wells can be supplied with different materials.
We can produce API 11AX cobalt alloy balls and valve seats, which have the advantages of high hardness, wear resistance, corrosion resistance, etc.
Each of our ball and seat combinations is vacuum-tested to ensure a perfect seal at all contact positions.
