• Dutco Tennant LLC, PO Box 233, Dubai, U.A.E.

Dutco Tennant LLC provides Flap valves which are designed to operate under very low water heads, in gravity flow applications, and at ambient temperature conditions between -65° and +85° C. The valve prevents back flow of water via a spring-loaded or weighted flap kept across a pipe opening, tube or duct.

In our Flap Valves, the flap and back plate are made using HDPE, with a stainless steel 316 hinge-pin, counterweight and attachments. As the HDPE has specific gravity, a stainless steel counterweight is provided to ensure closure when back-pressure is present; however low heads of water are needed to open the flap. It has such design that the counterweight balances the flap accurately.

Our Flap Valve has a lip seal, to offer seal between the frame and flap, and also there is a self-adhesive neoprene seal to place between the wall and the frame, which is there to prevent leakage.

Our company offers wall-mounted Flap valves which are till 1000 mm in size and spigot-mounted Flap valves till 600 mm. We provide Flange-mounted, Tidal Flap valves, and other Flap valves on request.
