180G0031

The 180G0031 pressure relief valve belongs to the VRH Pressure Relief Valves series and is produced by Danfoss. It is installed in hydraulic circuits to open at a preset pressure and protect components from overload. The valve body is built from AISI 304 stainless steel to resist corrosion when exposed to common hydraulic fluids. A BSP threaded interface allows direct integration with pipework using that connection standard. The 3/8 in port size matches medium-flow lines typical of compact power units, and the design safely handles media temperatures up to 50 °C so elevated oil heat does not compromise sealing.

During assembly the housing should be tightened to 30 Nm, a limit chosen to secure the threads without distorting the seat. This controlled preload keeps the seal intact during repeated pressure cycles. The component weighs 0.594 kg, enabling straightforward installation in manifold blocks without heavy supports. Its internal cavity holds 0.424 L, giving adequate volume for pressure dissipation when the valve lifts and helping to reduce shock in connected lines. Together these characteristics support consistent pressure control in small to mid-size hydraulic systems operating within mobile or stationary equipment.
