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.

Poppet check valve Figure 1.3 provides two schematic drawings showing the operation of a poppet check valve . A poppet is a specially shaped plug element held on a valve seat by a light spring. Fluid flows through the valve in the space between the seat and poppet . In the free flow direction, the fluid pressure overcomes the spring force .

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.

Hydraulic valves are mechanical equipment for controlling the flow of fluid in hydraulic pipes or systems. They can be utilized to thoroughly check the flow level to a specific domain, redirect pressurized fluid or close a line. Hydraulic valves can be used to control the flow of fluid in a circuit as well as the quantity of fluid power.

Side to Nose Check Valve Side to nose check valves are a special type of check valve where the free flow path is from the side of the cartridge valve to the nose. They functionally are the same as the standard check valve. Side to nose check valves are occasionally used by manifold designers to simply the flow path design of their blocks.
