The working of a Pressure Seal Swing Check Valve is based on the movement of a disc inside the valve body. The disc is connected to a valve stem, which is connected to an actuator. The actuator opens and closes the disc as required, allowing fluid to flow in one direction and preventing backflow.

Here is how the valve works:

1. Normal fluid flow: When fluid flows in the correct direction through the pipeline, the disc is held open by the fluid pressure, allowing the fluid to flow freely through the valve.
2. Reversed fluid flow: When fluid flow reverses, the disc automatically swings shut, preventing backflow through the valve. The tight seal provided by the pressure seal mechanism ensures that backflow is prevented, even at high pressures.
3. Reopening the valve: When fluid flow returns to the correct direction, the actuator opens the disc, allowing fluid to flow freely through the valve once again.

Australian Valve is the leading Pressure Seal Swing Check Valve Manufacturer & Supplier in Australia and provides reliable operation, ensuring that backflow is prevented in pipelines. The valve’s pressure seal mechanism allows it to handle high-pressure systems, making it ideal for use in pipelines where high-pressure fluid flow is required.
