Pressure Relief Valve DBW20A3-5X/350S6EG24N9K4R12V - Bosch Rexroth R901256344
When flow exceeds what size 10 can handle, the pressure relief valve has to move up a step. The DBW20A3-5X/350S6EG24N9K4R12V relieves up to 500 l/min in size 25, limits from 4 to 350 bar and is built with FKM seals.

Description
A valve working at its limit heats the oil and loses setting accuracy. The pilot-operated DBW20A3-5X/350S6EG24N9K4R12V is therefore laid out for size 25 and relieves up to 500 l/min while holding pressure in the range from 4 to 350 bar.
Benefits
- Relief flow of up to 500 l/min in size 25 through the subplate mounting to ISO 6264-08-13
- Setting range 4 to 350 bar on a lockable rotary knob with scale
- FKM seals instead of the standard NBR build, HL hydraulic fluid
- Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803
- Weight of 5.92 kg with two switching positions and two ports
Application
The place for this valve is the main circuit of a power unit with a large pump, where the whole delivery passes across the valve during relief. Size 25 with the interface to ISO 6264-08-13 is the matching step for that. The maximum operating pressure of 350 bar also covers circuits run above the usual 315 bar nominal level.
