Pressure Relief Vaive DBD 06 Pressure Relief Valve direct operated Nom. size Nom. flow capacity Nom. operating pressure 06 40 1/min 400 bar Description Direct spring pressure relief valve, type DBD, are suitable for inline mounting and serve for limitation of operating pressure in hydraulic Systems. The operating pressure is optionally adjustable by hexagon socket grub screw (with protection cab) or by knob. The relief valves are available in diffrent pressure ranges. The valve is equipped with a valve seat sealed by a spring loaded poppet. If the set spring force is overcome by the line pressure the poppet Jtfts up from the seat and gives free flow from pressure to drain chamber. The valves are available as cartridge or inline pressure relief valves.
