Power Station Check Valve

Product Detail

Features

  1. Product design is in accordance with NB/T47044-2014 and ASME B16.34-2013 standards;
  2. The valve body cavity adopts a pressure self-tightening sealing structure (Wood seal). The higher the pressure in the valve body cavity, the better the sealing performance.
  3. Adopts swing structure with small flow resistance.
  4. The valve seat and valve disc sealing surface are made of cobalt-based hard alloy surfacing or plasma spray welding, which has good high temperature resistance, wear resistance and abrasion resistance.
