Pressure Relief Valve DBW20A3-5X/350S6EG24N9K4R12V - Bosch Rexroth R901256344

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

Technical data

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.
