Relief valves

Our relief valves are well suited for example for snow ploughs and on-road and off-road vehicles, tractors, and other mobile equipment. They protect the cylinders and the machine from external shocks, or they will reduce the pressure level of the cylinder. Most models are designed in co-operation with the customers for certain applications.  In most relief valves there is an inlet valve, which prevents formation of vacuum in the hydraulic cylinder. Thanks to the inlet valve the hydraulic cylinder will not make excessive movements, even if the shock is directed towards the piston side.
