Pressure Relief Valve DBW52BF3-3X/100U6EG24N9K4 - Bosch Rexroth R901126308

Large pump circuits call for a valve section that passes full flow without a pressure spike. The DBW 52 accepts up to 2000 l/min, limits system pressure within 3.9 to 100 bar and switches to unloaded circulation through the built-on directional spool valve.

Benefits

• Up to 2000 l/min flow through the size 52 flange connection.
• Pressure adjustment range 3.9 to 100 bar, lockable rotary knob with scale.
• Unloading to open circulation through the built-on directional spool valve with 2 switching positions.
• Pilot-operated pressure valve in poppet seat design, rated to 315 bar maximum operating pressure.
• 28.8 kg weight, 24 V DC solenoid actuation through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals.

Applications

Sits in the pressure line of large power units, on presses and on test rigs with high pump volume. The lockable knob secures the set pressure stage against unauthorised adjustment. The solenoid unloads the pump during start-up and idle periods.
