CS03B50

The CS03B50 relief valve belongs to the Pressure Control Valves series and is manufactured by Vickers for hydraulic automation that requires dependable pressure limitation. It uses a SAE straight thread connection so technicians can screw it directly into a standard cavity without adapters. The body length is 6.630 inches (168.402 mm), giving room for the poppet, spring, and damping passages that open when system pressure reaches the set point. A width of 2.190 inches (55.626 mm) allows the valve to occupy minimal manifold face area, while size 03 aligns with commonly drilled port patterns in medium-flow circuits.

The model stands 5.640 inches (143.256 mm) tall, providing enough vertical space for the spring chamber yet remaining short enough for shallow control blocks. This height, combined with the footprint noted earlier, yields a compact profile that lets designers place pressure limiting hardware close to pumps or actuators to reduce drop across the line. Uniform machining practices at Vickers hold cartridge tolerances tight, supporting repeatable cracking pressure and swift reseat behavior during rapid duty cycles in automated machinery.
