The principles and difference between one-way valve and check valve
One-way valve is sometimes called a check valve. One-way valve is a device in which fluid can only flow along the water inlet, but the medium at the outlet cannot flow back. The function of the check valve is to prevent the medium in the pipeline from flowing back. So what is the difference between […]
The difference between one-way valve and check valve
One-way valve means that the fluid can only flow along the water inlet, and the medium at the water outlet cannot return. Used in hydraulic systems to prevent reverse flow of oil or pneumatic systems to prevent reverse flow of air. Check valve refers to a valve whose opening and closing parts are circular discs […]
What is double plate swing check valve
Main features of Double plate swing check valve: Two valve plates are fixed on the valve body along a pivot axis, and two springs are installed on the butterfly plate above the sealing surface. Driven by the pressure of the medium flow, the spring is compressed to force the butterfly plate to open. When the […]
