Flap valves are made of cast iron, stainless steel, aluminum, or rubber depending on the type of service. Small differential pressure on the back of the flap gate causes it to open automatically to allow discharge through levees, sewer lines or drainage conduits. When water on the face side of the gate rises above the water on the backside, the gate closes automatically to prevent backflow. Flap valves are equipped with flat-back seats for attaching to wall thimbles, headwalls, and existing pipe flanges. The seat or frame of the flap gate is attached to a wall or pipe flange and forms the opening through which water passes.
Dutco Tennant LLC provides Irrigation Pumping Station Flap valves – these valves can work in different temperature and environment conditions. They are fit for gravity flow applications and wide temperature range application. The Flap Valves are used to prevent backflow of water via a spring-loaded Flap present at the pipe’s opening. Our company offers Flap Valves, in these valves, the Flap and Backplate are made with HDPE and Stainless Steel.
As HDPE has specific gravity, these valves are provided with Stainless Steel counterweight to ensure that Valve closes when there is back-pressure. Nevertheless, low water-heads are required to open the flap. These Valves have a good design, and hence the counterweight in the Valve balances the Flap accurately. We offer Flap Valves with lip seals, and they provide a seal between the Frame and the Flap. Plus, there is a neoprene seal to stop leakage. We can also provide Flange-mounted, Tidal Flap, and other Flap valves based on your requirement. Dutco Tennant LLC provides good-quality Flap valves for our respected clients in the Middle East and GCC area.
