Pressure Relief Valve DBW20B1-5X/200Y6EG24N9K4E - Bosch Rexroth R901231260

Manual adjustment and high delivery do not exclude each other. This version takes up to 450 l/min and lets the cut-off pressure be set between 4 and 200 bar on a rotary knob. The pilot-operated poppet valve mounts on a subplate to ISO 6264-08-13 and weighs 5.44 kg.

Benefits

• Rotary knob for a setting range of 4 to 200 bar without a tool
• 450 l/min flow rating for power units with high delivery
• Pilot-operated poppet valve in size 25 with spool symbol B
• Subplate mounting to ISO 6264-08-13, maximum operating pressure 350 bar
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.44 kg mass, NBR seals for HL hydraulic fluid

Application

The version fits power units on forming lines and test benches where system pressure is part of the process and the pump delivers a lot of oil. The operator sets the value on the knob without opening the valve or reaching for a tool. Solenoid actuation switches the circuit independently of that.
