VAU 3/4” (V0460 – 300 bar) – Cross-line Pressure Relief Valve

Product description:

The V0460 type VAU 3/4” cross-line pressure relief valve consists of two intersecting relief units designed to safely limit the maximum pressure in hydraulic cylinders and hydraulic motors. The valve provides excellent protection against sudden pressure spikes (antishock phenomena) and allows each line to be set to different pressure values. The 300 bar configuration is ideal for heavy-duty hydraulic systems. The valve body is made of zinc-plated steel, while the internal components are heat-treated and precision-ground steel, providing long service life and minimal internal leakage.

Details

Operating principle

The valve contains two independent pressure relief cartridges one for each direction of flow. When pressure in either direction exceeds the pre-set limit, the corresponding cartridge opens and diverts excess oil to the tank (or low-pressure side), preventing system overpressure.

This ensures safe pressure regulation in both directions, regardless of flow direction. The integrated spring-loaded mechanism allows the valve to close quickly after pressure returns to normal, maintaining stable and reliable hydraulic system performance.
