1300mm circular HDPE flap valves are for use with pipework up to 1300mm. Circular flap valves are recommended for use in emergency situations to protect against and prevent flooding during periods of extreme weather. Our circular flap valves are usually installed above the normal water level to prevent back flow up a pipe during times of heavy rain and flooding. The PTK-G flap valve is suitable for use with a water pressure of 5 MWC for 72 hours and 1 MWC for 50 years. Althon circular flap valves are HDPE with HDPE ribs and can be further reinforced where necessary with stainless steel.
