180G0033

The 180G0033 pressure relief valve belongs to the VRH Pressure Relief Valves series and is produced by Danfoss for hydraulic automation where line over-pressure must be vented safely. Its body is made from AISI 304, giving resistance to corrosion and providing long service life with standard hydraulic media. A 3/8 in port size fits compact circuits, and the BSP connection standard matches widely used British parallel pipe fittings for quick installation. A minimum pressure setting of 30 barg defines the lowest relief point to avoid premature bypass, while a 5.3 mm setting screw span permits precise manual adjustment across the usable range.

The valve can be set up to 120 barg, establishing the maximum allowable pressure before relief to protect downstream components from overload. It passes up to 5 l/min, matching low-flow hydraulic pilot lines or small actuators without causing excessive backpressure. Internal leakage is limited to 0.3 l/min so energy loss and heat generation remain low during standby conditions. A maximum media temperature of 50 °C indicates the thermal limit for the fluid, ensuring seal integrity and consistent performance when oil temperatures rise during duty cycles.
