The working principle of the JHY Cast Iron Dual Plate Wafer Check Valve is as follows:

When there is forward flow in the pipeline, the media enters through the valve’s inlet port and flows through the open valve disc. The dual plates are designed to be lightweight and streamlined, allowing smooth flow with minimal pressure drop. This ensures efficient flow and reduces energy loss.

When there is a reverse flow or backflow in the pipeline, the differential pressure between the upstream and downstream sides of the valve causes the valve disc to close. The dual plates pivot to a closed position to block the flow and prevent backflow from occurring.

The closing action of the valve is accomplished by the force exerted by the flowing media itself. This self-acting design ensures quick and automatic closure of the valve in response to backflow conditions. The quick closure helps to minimize water hammer and protect the system from damage.

Once the backflow is stopped and the differential pressure decreases, the valve disc opens again to allow forward flow. The dual plates return to their open position to facilitate the smooth and uninterrupted flow of media through the valve.

The working principle of the JHY Cast Iron Dual Plate Wafer Check Valve is based on the differential pressure and the design of the dual plates, providing reliable backflow prevention and efficient flow control in pipeline systems.
