Pressure relief valves are used in hydraulic systems to limit the system pressure to a specific set level.
If this set level is reached, the pressure relief valve responds and feeds the excess flow from the system back to oil tank.
Hidros provide inline pressure relief valves with different setting ranges.
VMPD series have two relief valves that provide overload protection in two hydraulic lines with one tank connection. Valve also enables to set different pressure settings in these lines.
