The KCG3160DZMUHA110 pressure relief valve is part of the Pressure Control Valves series from Vickers. Designed for hydraulic automation systems, it controls pressure through a proportional pressure relief element. The unit is solenoid controlled, so an electrical signal varies the relief setting without manual adjustment. A 24 V DC coil supplies the magnetic force required to position the spool during operation. The electrical connection follows the ISO 4400 (DIN 43650) pattern, allowing quick replacement with standard cable plugs. It mounts on an ISO4401-03 / NFPA D03 / CETOP 3 / NG06 interface, and the subplate style keeps line plumbing on a manifold rather than the body. The valve is built as a single-stage device, reducing internal volume and response time, and it tolerates system pressures up to 350 bar.
The maximum flow of 5.0 L/min matches small displacement actuators and pilot circuits. A tank port rating of 210 bar protects the return line components when downstream pressure rises. Viton seals are fitted to handle common hydraulic oils and resist swelling under temperature and fluid additives. Cleanliness of the working medium must be maintained at 17/15/12 to prevent wear of the precision metering edges. The valve remains functional at ambient and fluid temperatures from -20 °C to 70 °C, covering typical mobile and industrial service conditions. These operating limits direct users to size pumps, coolers, and filtration so the valve can deliver consistent proportional pressure control.
