Check Valve
Check Valve (Double Door)
- 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.

Bronze Swing Check Valve
- Check valves permit flow in one direction only and close automatically if flow reverses. They are entirely automatic in action, depending upon pressure and velocity of flow within the line to perform their functions of opening and closing
- PN25
- DN ¾"-2"
Check Valve (Double Door)
- The Watts Wafer Style Check Valve is designed to automatically open the valve by the flow of medium itself, and close the disc relying on the spring torsion and medium flow, which is used to prevent the backflow of medium. It’s generally used in building services
