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.
