Valve ball valve seat

Widely used in oil drilling, deep sea drilling pump valve ball, ball seat, is also one of the key components of the pump.Due to the harsh working environment and conditions in the oil drilling industry, water, various gases, wax, sand and other highly corrosive substances are usually contained in sand-containing wells, heavy oil wells and high-pressure reverse dredging wells.Oil pumps need to extract petroleum from a stratum of hundreds of meters or even thousands of meters, which requires the valve ball and valve seat to have good sealing, wear resistance and corrosion resistance
