Pressure Relief Valve DBW20B3-5X/315U6EG24N9K4/12 - Bosch Rexroth R978017721

A setting range starting several bar up is no use for circuits held at low pressure. The pilot-operated DBW20B3-5X/315U6EG24N9K4/12 puts its lower limit at 2 bar and covers from there to 315 bar, with a relief flow of up to 500 l/min in size 25.

Benefits

• Setting range 2 to 315 bar, the lower end sits in the band of small holding pressures
• Relief flow of up to 500 l/min through the subplate mounting to ISO 6264-08-13
• Spool symbol B, two switching positions across two ports
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803
• Weight of 5.3 kg, NBR seals, maximum operating pressure 350 bar

Application

The build suits circuits kept at low pressure between load phases, for example accumulator charging and pre-load circuits. The lockable rotary knob with scale secures the setting against accidental turning. At 5.3 kg the valve stays easy to handle in size 25 during installation and removal.
