Before pump commences oil flow, the springs will be fully expanded to the lfulit of the housing or compartment r*rere they are located.They can be ccmpressed or expanded by oil pressure, but will return to t.heir original length r^rhen the system is depressurized. VALVES: 3. 4.

Check valves are also a major component in hydraulic processes which saves your system against a very costly shutdown. They are used for flow, directional, and pressure control. They are critical in preventing pressure build-ups and fluid restrictions, which can lead to system failures.

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 .

Check Valves 2 Introduction Vickers inline, right-angle, and manifold mounted check valves are direct operated and used in hydraulic circuits to allow the free flow of fluid in one direction only. The graphical symbol for these valves is a spring-loaded ball and a seat, as shown below.

Hydraulic Valve Division Elyria, Ohio, USA General Description Series C check valves permit free flow in one direction, and dependable shut-off in the reverse direction. Operation When pressure going through the valve is increased to the cracking level, the valve opens. When the pressure is reduced to below the cracking level, the valve closes

The three basic functions of valves are: 1. to stop flow, 2. to keep a constant direction of flow, and 3. to regulate the flow rate and pressure. To select the correct valve to fulfill these functions properly, an outline of the different types of valves and their features is given below. Butterfly valve

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.
