Product Description
Silent check valves, also known as non-slam check valves and spring-assisted check valves reduce or eliminate water hammer and its effects.
Water hammer refers to the high-pressure shock waves that occur when the flow of fluid abruptly stops (due to pump shut down or a valve disc quickly closing) in a piping system. When water hammer occurs, the resulting flow reversal places severe stress on the pipe, endangering its structural integrity, and opening it to potential rupture and damage. Swing check valves, tilting disc check valves, and double door check valves, among others, often contribute to water hammer problems.
To control water hammer and reverse flow, the use of silent check valves is recommended. When the source moving the fluid shuts down and the forward flow of the fluid decreases, the specially designed stainless steel spring action of the silent check valve controls the valve disc closure to occur prior to flow reversal. This spring assist insures that the valve does not slam shut, and the occurrence of water hammer is eliminated.
