Check Valve – CV These seat type valves allow free flow in one direction and offer leak free closure in opposite direction. Available as inline mounting, 

Pilot operated check valve modules are available in SINGLE ACTING and DOUBLE ACTING version: in both cases, one of their basic parameters is the Pilot Ratio “R”, defined as Pilot

Check Valve. The simplest DCV (Direction Control Valve ) is a check valve. A check valve allows flow in one direction, but blocks the flow in the opposite direction. It is a two-way valve because it contains two ports. Figure shows the graphical symbol of a check valve along with its no-flow and free-flow directions.

Hydraulic Cartridge Systems Check Valve With Thermal Relief The check valve with thermal relief performs the same function as a standard check valve. It allows free flow in one direction. In the opposite direction, it performs as a normal check valve preventing flow, while also venting excess pressure caused by the thermal expansion of fluid.

In a hydraulic system, shut-off valves serve to check flow in a preferred direction and allow free flow in the opposite direction. They are designated as check valves. The shut-off valves are designed as poppet valves and therefore provide leak free closure. A ball or poppet is generally used as the closing element.
