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 […]
