Hydro Gate® flap gates are made of cast iron or ductile iron, depending on the type of service. A small diferential pressure on the back of the gate causes it to open automatically to allow discharge …

A flap gate is a flow control device that, in principle, functions as a check valve, allowing water to flow through it in only one direction. The flap gate usually consists of a flat plate that is hinged at the top …

Flap gates are pivotal hydraulic engineering components designed to regulate water flow in various settings. Hinged at one end, they can be raised or lowered to control the passage of water...

Flap gates rely on simple yet effective mechanics. When water pressure on the upstream side exceeds the force of the gate’s weight and seal, the flap opens to allow flow. Once the pressure equalizes or …

A flap gate operated by a hydraulic cylinder is a mechanism commonly used in various hydraulic systems for controlling the flow of water. The operation involves a hinged gate, known as the...

A small differential pressure on the back of the 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 …

But how does a flap barrier gate work, and why is it preferred over other types of turnstiles? This article explains the working principle, key features, and common applications of flap barrier gates.
