Explore Troy Valve's high-performance standard flap check valves and gates for optimal flow control and debris prevention in water management systems.

HDPE Flap Valves from Fernco provide a high strength, low cost solution, preventing backflow through drain or sewerage pipes. Flap Valves are one-way valves which are installed at the open end of a pipe line or culvert.

Flap Valves, sometimes referred to as Flap Gates, are put on the end of a flanged pipe to allow the flow of water out of the pipe, but prevent anything from flowing back in, such as sticks, leaves or other debris.

Flood Valves are designed for backwater protection of drainage systems. Made to fit within the tile outlet, this cast aluminum valve has a minimum amount of resistance to outflowing water. The valve comes complete with stainless steel mounting bolts for a quick and affordable installation.

Althon manufacture and distribute flap valves in HDPE, cast iron and stainless steel. Flap valves and flap gates are a type of non-return valve (NRV) used to prevent flooding and to stop water back-flowing up pipework connecting into ponds, ditches, swales, rivers …

Flap valve is a type of one-way valve that uses a hinged flap (or disc) to allow fluid flow in one direction and prevent backflow in the opposite direction. The valve opens when fluid pushes the flap in the direction of flow and closes when the fluid …

WaFlap flap valves prevent backflow for storm water and wastewater in pipe systems, chambers and basins. Used in ports, rivers and coastal areas. Solution-focused

As a robust non-return valve (NRV), the HDPE Flap Valve allows water to flow in one direction while automatically closing to prevent any reverse flow when water pressure decreases, making it ideal for tidal zones, ponds, rivers, stormwater systems, …

A flap valve is a basic one-way valve that allows gases or fluids to flow in one direction while blocking flow in the other. A spring-loaded or weighted flap is put across the opening of a pipe, tube, or duct to achieve this goal.

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.
