The free swing design of the swing check valve enables the valve to be closed by the weight of the valve disc to prevent the turbine from being damaged due to reverse flow.

The double red check valve is a valve that automatically opens and closes the valve disc according to the flow of the medium itself and uses a rotating shaft to prevent the medium from flowing back. Also known as a one-way valve and return valve.

The swing check valve is applicable to the pipeline with a working temperature of - 29 ℃ to 425 ℃ and the medium of water, steam, oil, etc. It is used as a single hoist to prevent the reverse flow of the medium on the pipeline.
