The CG5V 6CW D M U B7 10 relief valve is manufactured by Vickers and belongs to the Relief Valves series. It is a solenoid-controlled, pilot-operated relief design intended to regulate hydraulic system pressure in automated machinery. The unit is built in valve size 06, a dimension that aligns with common industrial manifolds. A maximum rated pressure of 210 bar (3000 psi) defines the highest working limit it can hold. The internal passages support a rated flow of 227 l/min (60 USgpm), allowing high-volume circuits to pass without excessive drop. Installation is possible on a manifold or a subplate, simplifying integration into both new and existing blocks. The pressure port uses a 1.0625-12 UN-2B thread, matching standard size-06 tooling. Coil options include 220 V AC at 50 Hz and 230 V AC at 60 Hz so the same valve can operate on either line frequency. An ISO 4400 (DIN 43650) connector supplies the electrical interface for the solenoid.
The valve weighs 8.4 kg (18.5 lb), a figure to consider when determining support on the mounting surface. A high-vent spring is installed to accelerate pressure release once control current is removed. Lead wires are constructed to insulation class H, permitting coil temperatures associated with heavy-duty service. The design allows a maximum cycling rate of 4 Hz on alternating-current power, establishing the fastest permissible sequence of pressure changes. The tank return port can tolerate transient pressures up to 155 bar (2250 psi) without damage. Typical shift time during AC energization is 12 ms, indicating the response speed when the valve opens. Typical spring return time is 22 ms, describing how quickly the poppet reseats after de-energization.
