Direct-operated pressure relief valve DB 6 series

hydraulicpoppet

For subplate mounting 3 pressure-adjustment elements, optionally: • Sleeve with internal hexagon • Rotary knob, lockable, with scale • Rotary knob with scale 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. 01 Pressure relief valve 03 direct operated 04 Pressure limitation in channel P Pressure limitation in channel P and B PB 05 Connection porting pattern according to ISO 6264 W Adjustment elements 06 Sleeve with internal hexagon 2 Rotary knob, lockable, with scale1)​ 3 Rotary knob with scale 7
