VAU 3/8” (V0440) – Cross-line Pressure Relief Valve

Product description:

The V0440 type VAU 3/8” cross-line pressure relief valve is a combination of two intersecting safety valves designed to protect hydraulic cylinders and hydraulic motors. Its function is to limit the maximum pressure on both lines, safeguarding the system against sudden pressure spikes, overloads, and potential damage. This valve is ideal for anti-shock applications and allows different pressure settings between the two working ports. The valve body is made of zinc-plated steel, while the internal components are heat-treated and ground steel, ensuring high durability and minimal internal leakage.
