A spring-assisted in-line check valve uses a disc fitted with a valve seat and pressed into place by a spring. That spring keeps tension on the disc until the pressure is great enough to push it back. That allows water to flow in one direction.

Because the spring is a constant pressure, it closes the valve as the pressure lessens. That means that the disc has a shorter distance to travel to close off the valve, so flow is shut off quickly and tightly. The quick closing time helps prevent pressure surges in the line which could cause damage to the plumbing.

That quick and quiet closing action is where the valve gets the name “silent check valve.”

Spring-assisted check valves also have the benefit of being installable vertically, horizontally or at any angle, meaning they are more versatile in some situations.
