Swing Check Valve

The valve plate of the rotary check valve is circular and vertically hung on the valve stem. The valve plate and seat sealing ring of the single valve plate rotary check valve have the same slope, and are closed and sealed by the weight of the valve plate and the reverse pressure. The valve stem of the butterfly double disc rotary check valve also has a spring, which closes the valve by the spring force and reverse pressure. The swing check valve produced by Shanghai Meiyan Yi Pump Valve is a one-way valve, also known as a check valve, which prevents damage to upstream pipeline equipment caused by backflow of pipeline medium, especially at the outlet of the water pump, to prevent damage to the water pump caused by backflow of medium caused by water hammer. Swing check valve is an automatic valve that opens the valve by pushing the valve disc open under the pressure of the flowing medium in the pipeline, and closes the valve by the self weight of the valve disc, spring elasticity, and backflow water pressure.
