Forged Steel Swing Check Valve

The sealing pair is matched reasonably, and the sealing surfaces of the valve disc and seat are made of alloy steel, iron-based alloy, or Stellite cobalt based hard alloy overlay, which has good wear resistance, high temperature resistance, corrosion resistance, and abrasion resistance, and a long service life. Piping flange standards and flange sealing types can be adopted to meet engineering needs and user requirements.
