Swing check video

A new video from Val-Matic uses a side-by-side comparison of its Swing Check Valve with a conventional swing check valve to demonstrate a big industry concern. Both use a lever, weight and air cushion closure, but Val-Matic's valve features a high-performance air cushion that closes the valve faster. The video, "Closing Faster = No Slam!", shows the air is pressurized and accelerates the closure of the valve before a significant amount of reverse flow can develop. The video further illustrates that Val-Matic's valve closes in half the time compared to the conventional swing check valve and is virtually silent. It is typically used when multiple pumps are used to deliver water or when pump stations are protected from surges with a hydro-pneumatic tank.
