The CGR02CK30 valve belongs to the Pressure Control Valves series from Vickers and serves hydraulic automation by providing remotely adjustable pressure relief in pilot circuits. As a remote control relief valve, it sends a controlled pilot signal that limits system pressure at a downstream main valve. Subplate mounting speeds replacement on standardized pads, and a knob adjustment lets maintenance staff vary the setting without dismantling plumbing. The relief point can be tuned up to 140 bar, while the assembly withstands a rated pressure of 210 bar during peaks. Flow properties are defined by a 6.35 mm nominal passage and a 10.3 mm outlet port, both sized for typical pilot lines. A 9/16-18 UNF-2B vent thread accepts common hose fittings, and a mounting pad flatness of 0.013 mm promotes a reliable seal against the manifold.
Surface integrity at the interface is further supported by a 63 microinch finish that minimizes leakage paths under high pressure. The valve operates with fluid cleanliness to ISO code 19/17/14, reducing contamination-related wear on the internal poppet. A maximum fluid temperature of 66 °C maintains elastomer life and stable relief characteristics. Technicians can handle the unit easily because it weighs 1.4 kg, and space planning is simple thanks to a height of 155.194 mm, a length of 47.498 mm, and a width of 71.374 mm. These dimensional and service limits guide manifold designers in allocating envelope clearances, coolant capacity, and filtration so the CGR02CK30 performs consistently in pressure control stages.
