CARBIDE VALVE ROD/BALL/SEAT

  Cemented carbide ball valve or cemented carbide ball valve is evolved from the traditional plug valve, and its opening and closing part is a ball, which can be opened and closed by the ball around the stem axis. Widely used in oil drilling, deep-sea drilling pump valve ball, ball seat, which is also one of the most critical parts of the pump. Due to the harsh working environment and conditions in the oil drilling industry, there are usually water, various gases, wax, sand and other highly corrosive substances in sand bearing wells, heavy oil wells and high-pressure anti drainage wells.
  The oil pump needs to extract oil from hundreds or even thousands of strata, which requires its valve ball and seat to have good sealing performance Wear resistance and corrosion resistance (after the valve ball and valve seat are matched, vacuum to the absolute pressure below 0.36kgn/cm, and the pressure value does not change within 10s).
