Pressure Relief Valve DBW 20 B2-5X/200-6EG12N9K4/12=CSA - Bosch Rexroth R978020064

A 24 V solenoid cannot be switched reliably from a 12 V supply, and a converter only adds another point of failure. The DBW 20 B2-5X/200-6EG12N9K4/12=CSA is therefore rated for 12 VDC and limits pressure between 4 and 200 bar.

Benefits

• 12 VDC supply voltage, driven straight from the on-board electrical system.
• Adjustment range 4 to 200 bar at a permitted operating pressure of 350 bar.
• 500 l/min in size 25, pilot-operated seat valve with symbol B.
• Subplate mounting to ISO 6264-08-13, connector 3-pole (2 + PE) to EN 175301-803.
• 5.3 kg, internal hexagon with protective cap, NBR seals for HL hydraulic fluid.

Applications

The valve limits pressure in power units of vehicle bodies, lift platforms and mobile test equipment on a 12 V supply. A range up to 200 bar covers the working pressures usual in such systems. The second switching position is selected by the solenoid from the vehicle control.
