Althon - Model 100mm - Tidal Flap Valve Brochure

100mm tidal flap valves are recommended for use below the waterline and in tidal applications for pipework up to 100mm. Our tidal flap valves are typically installed below the normal water level to prevent back flow up a pipe. Althon tidal flap valves are suitable for use with a water pressure of 5 MWC for 72 hours and 1 MWC for 50 years. The flap valve is HDPE with HDPE ribs and can be further reinforced where necessary with stainless steel. We offer a range of standard sizes form 100mm to 2000mm and can quote for bespoke sizes as required. We can also offer rectangular tidal flap valves on request.
