Flexseal HDPE 150mm Wall Mounted Flap Valve
Product code: FV150-INT
Flap valves are designed to operate under very low heads of water, in gravity flow applications, at ambient conditions between -65° and +85° C. The valve prevents backwater via a spring-loaded or weighted flap placed across the opening of a pipe, tube or duct.
In Flexseal Flap Valves, the flap and backplate are manufactured in HDPE, with a stainless steel 316 hinge-pin, counterweight, and attachments. Due to the specific gravity of the HDPE, a stainless steel counterweight is fitted to ensure closure when back-pressure is present; however, very low heads of water are required to open the flap, as the design is such that the counterweight balances the flap correctly.
The Flap Valve incorporates a lip seal, to provide the seal between the flap and frame, and also a self-adhesive neoprene seal to install between the frame and wall, which is fitted to prevent leakage.
Benefits
Lighter-weight than traditional cast iron flap valves, leading to easier installation and lower installation costs
Heavy-duty HDPE will withstand being struck by rocks and other debris, present in marine and river environments, which would shatter lighter-weight plastics
Waterproof qualities all the way through, not reliant on maintaining an added layer
Not at risk from theft as no inherent scrap value
25-year minimum life expectancy
Manufactured to DIN 19569-4
Flap valves are supplied in accordance with ISO 9001:2008 requirements
