Product DescriptionProduct DescriptionDBW30 Hydraulic Pilot Operated Electromagnetic Relief ValveThe DBW30 Hydraulic Pilot Operated Electromagnetic Relief Valve is a high-performance component designed for reliable pressure control and system unloading in industrial hydraulic systems. As a two-stage, two-spool valve, it combines a main valve with a pressure-setting pilot valve and an integrated directional spool valve.Its primary function is to limit system pressure to a preset value, thus protecting the hydraulic system from excessive pressure, and to allow for magnetic unloading of the system on command. The valve can be unloaded at any time by energizing the solenoid of the mounted directional valve. This makes it particularly suitable for applications requiring high flow rates and precise pressure management, such as in injection molding machines, hydraulic presses, and other heavy machinery.Key features of the DBW30 series include a compact design, high flow capacity, and options for different pressure adjustment elements like knobs or covered setting screws. Some models also offer an optional shift-time delay with a dashpot, which can delay the opening of the connection to avoid pressure peaks and noise in the return line. The valves are designed for subplate mounting according to standards like ISO 6264, and are available in different versions for internal or external pilot fuel supply and drainage.SpecificationNominal Size32Maximum Working Pressure350 barMaximum Flow Rate650 L/minPressure Setting Range4–350 barPort/Pressure Connections2Number of Switching Positions2Actuation TypeElectromagneticCommon Voltage24 VDCCompany Profile
