The stainless steel butterfly valve is one of our various material options, primarily used at the end of drainage pipes to prevent backflow of external water. The valve consists of four main parts: the valve seat, valve plate, sealing ring, and hinge, and can be manufactured in either round or square shapes.

The casting can be made into floating gate, flat gate, sleeve gate, and so on. It is a one-way valve installed at the outlet of drainage pipes along rivers and canals. When the river or canal tide level is higher than the outlet of the pipe and the pressure is greater than the pressure inside the pipe, the gate panel closes automatically to prevent the river or canal tide from backflowing into the drainage pipeline.

Stainless Steel Swing Gate Features: 1. Enhanced energy efficiency; door opening and closing require no manual force.

2. Long lifespan (simple mechanical structure, easy maintenance)

3. User-friendly, no manual operation required for switching on/off.
