HDPE Flap Valves
Waterfront have designed a range of ‘next generation’ HDPE (High Density Polyethylene) Flap Valves. This range comprises lightweight, corrosion resistant flap valves which act as Non-Return Valves and check valves for the prevention of reverse flows.
The product has been designed to be flexible to suit any installation type:
Wall mounted – this basic flap valve can be easily mounted to a flat wall to prevent reverse flow.
Spigot mounted – this type of valve can be mounted for a ‘push fit’onto the end of a pipe
Tapered spigot for a ‘push fit’ into existing pipes
Flange mounted – this range of valves is suitable for fixing to flanged pipes. We can supply to metric and imperial flange sizes to both BS and EN standards.
Tidal – Our tidal range is supplied with the door at a 10 degree angle suitable for tidal water situations. Other angles are available upon request.
All our valves suit different shaped outfalls (i.e. square, round, elliptical) and are suitable for pumped outfalls with integral stroke limiters and vent pipes.
Types: Square, Rectangular or Oval Shapes
Size Range: Standard 100mm – 1000mm, bespoke sizes can be designed to suit project specific requirements
