Pressure Relief Valve DBW20B2-5X/350S6EG24N9K4R12V=CSA - Bosch Rexroth R900248580

A circuit running 500 l/min needs its pressure protection on a pilot-operated valve in size 25. The DBW20B2-5X/350S6EG24N9K4R12V=CSA is a seat valve with spool symbol B, holds 350 bar maximum operating pressure and is set from 4 bar upwards through the internal hexagon under the protective cap. The subplate follows pattern ISO 6264-08-13 and a 24 VDC solenoid unloads the circuit electrically. Sealing is FKM for HL hydraulic fluid and the weight is 5.9 kg.

Benefits

• Maximum operating pressure 350 bar, adjustment starting at 4 bar
• 500 l/min flow at size 25
• Spool symbol B, 2 switching positions, 2 ports to ISO 6264-08-13
• Subplate mounting, seat valve of pilot-operated design
• Supply voltage 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• FKM seals, HL hydraulic fluid, 5.9 kg

Applications

The valve protects pumps and circuits that circulate up to 500 l/min. Keep the setting under 350 bar, because that figure is the ceiling of the valve itself and not an operating point. Check before mounting that the subplate and the fittings carry the same pressure rating. The protective cap over the internal hexagon keeps the set spring preload from being altered by accident.
