1.Introduction of Automatic Butterfly Check Valve

Automatic butterfly check valve is an automatic valve, its structure is similar to butterfly valve, its structure is simple, flow resistance is small, water hammer pressure is also small.
The disc of the automatic butterfly check valve rotates around the stem in the valve seat. When the medium passes through, the disc will open and the medium will pass through due to the pressure of the medium itself. When the medium comes back, the disc will close and block the medium flow due to the pressure of the medium and the gravity of the disc itself. The disc check valve has a simple structure and can only be installed on the horizontal pipeline.
