Pressure Relief Valve DBW20B2-5X/230-6EG24N9K4VE - Bosch Rexroth R901210648

When a circuit relieves up to 400 l/min, the size of the relief valve decides how much back pressure builds up. This pilot-operated seat valve in size 25 accepts that flow and holds pressure in the 4 to 230 bar range.

Benefits

• Setting range 4 to 230 bar as a pilot-operated seat valve, maximum operating pressure 350 bar.
• Flow up to 400 l/min in size 25 on connection diagram ISO 6264-08-13.
• FKM seals for HL hydraulic fluid, version with 2 ports.
• Electrical control at 24 VDC, 2 switching positions, 3-pole connector (2 + PE) to EN 175301-803.
• 5.38 kg weight with subplate mounting, spool symbol B, CE conformity.

Application

The valve protects pumps and lines in power units of medium to large delivery. Subplate mounting to ISO 6264-08-13 allows replacement without reworking the piping. The internal hexagon with protective cap guards the pressure stage that has been set against accidental adjustment.
