A Flap Valve, in simple words, permits gas or fluid to flow in one direction while preventing backflow. A spring-loaded or weighted flap affixed to the opening of a pipe, tube, or duct accomplishes this function. Flap valves are commonly used as industrial equipment to direct flow in the desired direction. They can be opened manually or remotely, and they can be opened by the force of the flow. The purpose of a flap valve is to send water out of a flanged pipe while preventing debris such as sticks and leaves from flowing back in. The valve will open when direct pressure is applied to it, and it will close when that pressure is alleviated. What is a Flap Valve? Flap Valves, also known as Flap Gates, are installed on the end of a flanged pipe to allow water to flow out while preventing detritus such as sticks, leaves, and other debris from pouring back in. The valve will open under direct pressure and close when the pressure from the outfall fluid is relieved. Function of a Flap Valve 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. The valve flap opens in the appropriate flow direction and is either forced open by the flow or opened remotely. The flap's spring or weight closes it against a seal when the flow stops or the remote actuation is released, essentially preventing fluid or gas from flowing back into the pipe. In addition, the flap valve keeps unwanted foreign objects out of the pipe or channel to which it is connected. Standard Features of a Flap Valve 1. Cast Iron Design The cast parts, as opposed to fabricated parts, have a lower risk of failure over time. 1. Machined Bronze to Bronze Seat The lid closes against a firm, smooth surface created by our machined seat. It can survive the most extreme situations. The robust to bronze seating is used on the 30" to 36" flap valves. 2. Two-Part Epoxy Coating The coating on our flap valves provides long-term corrosion prevention. 3. Stainless Steel Hinge & Cotter Pins Because our valve pins are constructed of stainless steel, they will not rust and bind the valve. 4. Optional Resilient to Bronze Seating This results in a softer reseating surface as well as a better seal. Considerations of Using the Flap Valves Operation The flap valve will swing open under direct pressure to release the outfall fluid and close when the direct pressure is alleviated if it is properly placed. To achieve positive seating, for example, the RSF Valve Flap Valve incorporates a 10-degree inclined seating plane.
