Pressure Relief Valve DBW30A2N5X/315YS6EG24N9K4R12E - Bosch Rexroth R901031946

A large power unit has to be limited to a fixed system pressure and switched electrically from the controller. The pilot-operated DBW30A2N5X poppet valve relieves up to 700 l/min and carries spool symbol A.

Benefits

• Adjustment range of 4 to 315 bar with a maximum operating pressure of 350 bar.
• 700 l/min of flow in size 32, enough for power units running several pumps.
• Pilot-operated poppet valve with two switching positions and spool symbol A.
• Setting through an internal hexagon with protective cap, which covers the setting against accidental adjustment.
• Subplate mounting to ISO 6264-10-17, 24 V DC solenoid through a 3-pole connector (2 + PE) to EN 175301-803.
• 7.1 kg with NBR seals for HL hydraulic fluid.

Applications

The usual place is the pressure line of large power units on presses, test benches and hydraulic stations. An adjustment range up to 315 bar leaves headroom below the 350 bar operating pressure of the series. The protective cap over the hexagon keeps the setting once it has been found.
