■ Preset pressure at 95 or 105 MPa.
■ Prevents your hydraulic system from pressure overload.
A safety valve is a useful component for preventing exces­sive pressures in a hydraulic system. These valves are primarily designed for use on the return side of double acting hydraulic cylinders, and are preset at the factory for maximum pressure as shown in the table. The preset pres­sure must NOT be changed.
If the preset pressure is exceeded then oil will leak out. You must therefore ensure that the user us protected against pressurised oil. Always install the safety valve in an enclo­sure or protected area.
