1100mm Flap ValvesSince the introduction of HDPE flap valves by ACE in 1997 the material has become synonymous with high quality, reliable flood defences. Offering extremely good value for money over its life- it’s not just any “plastic” valve it’s an ACE valve! We stock a wide variety flap valve sizes for quick dispatch (100-1000mm) however if our standard range does not meet your requirements our products can be customised to meet your needs (higher pressures, special sizes or pumped valves for example). All our standard flaps are made from the tried and tested UV stable black HDPE, stainless steel 316 and EPDM sealing systems. They come complete with fixing’s and seals required for installation (we can offer the valves without fixings on request).
