Closing Faster = No Slam! Video uses a simple demonstration to understand a big industry concern. The video shows a side by side comparison of a Val-Matic Swing Check Valve with a conventional swing check valve; both use a lever, weight and air cushion closure but Val-Matic’s is a high performance air cushion which closes the valve faster. Instead of closing similar to a storm door where the compressed air cushions the closure, the air is pressurized and accelerates the closure of the valve before a significant amount of reverse flow can develop. The Val-Matic High Performance Air Cushion Swing Check Valve closes in half the time compared to the conventional swing check valve and is virtually silent. The Val-Matic Swing Check Valve is typically used when multiple pumps are used to deliver water or when pump stations are protected from surges with a hydro pneumatic tank.
