Wafer Check Valve 866 (Cast Iron)
Fig. 861 (PN16) / 861A (ANSI 125) / 866 (PN25)
FEATURES & BENEFITS
- 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.
