Pressure relief valve dbds 4 K1X/200-090 SO156 Unpacked Weight: 0.075 kg Screw-in cartridge valve For applications with especially high tightness requirements Leakage-free up to a maximum of 80 % of the set cracking pressure 2 adjustment types, optionally: • Grub screw with internal hexagon • Hand wheel The pressure valve type DBD...SO156 is a direct operated pressure relief valve for the installation in block designs. It is used for applications with especially high sealing requirements for limiting a system pressure. The system pressure can be set via the adjustment type (4). The valve is closed in initial position. Via control line (2) and poppet (1), the pressure in the main port ① acts on the spring plate (5). If the pressure in the main port ① rises above the value set at the compression spring (3), the poppet (1) opens and the hydraulic fluid flows into the main port ②
