Предохранительный клапан, direct controlled DB6D

Description Size 6 Component series 1X Maximum operating pressure 315 bar Maximum flow 60 l/min Features For subplate mounting 3 pressure-adjustment elements, optionally: • Sleeve with internal hexagon • Rotary knob, lockable, with scale • Rotary knob with scale Product description General Pressure valves of type DB 6 D are direct operated pressure relief valves. They are used for limiting the system pressure. The pressure relief valves basically consist of the main valve (1) with main spool insert (2) and the pressure adjustment element (3). The pressure applied to channel P acts on the main spool (2). If the pressure in channel P exceeds the value set at the spring (5), the poppet (4) opens against the spring (5) and the main spool (2) is free to move accordingly against the spring. So hydraulic fluid flows over the control edge (6) out of channel P to T.
