Check Valves

Check valves are required to permit forward flow and prevent reverse flow. This is achieved through linear or rotary (angular) motion of a closure member which is kept open by the flowing fluid.

when the flow is reduced towards zero, or reversed, the closure member is moved against its seat by forces due to gravity, supplementary springs, and back pressure.

The self-acting principle of check valves introduces dynamic response as well static (flow configuration) considerations which must be studied in accordance to informed operating conditions.
