Wafer Check Valve 861 (Cast Iron)

Fig. 861 (PN16) / 861A (ANSI 125) / 866 (PN25)


  • Check valves permit flow in one direction only and close automatically if flow reverses, depending upon pressure and velocity of flow to perform the functions of the opening and closing
  • Non-Slam design as a result of rubber seat and spring-assisted closure
  • EPDM rubber seat to facilitate quiet operation and improve disk seating
  • Eyebolt tapped holes in sizes DN200 and above, to fit eyebolts to BS EN 1S0 3226: 2010 (eyebolts are not supplied with valve)
  • Design and construction lends itself to pump duty applications.
