Pressure Relief Valve DBW20B2-5X/315Y6EG24N9K4/12=CSA - Bosch Rexroth R901563503

An exposed rotary knob on a relief valve invites readjustment, and the process then runs differently from the documentation. The DBW20B2-5X/315Y6EG24N9K4/12=CSA instead uses an internal hexagon with a protective cap and limits pressure from 4 to 315 bar.

Benefits

• Internal hexagon with protective cap, the value set once stays in place during operation.
• Adjustment range 4 to 315 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, two ports, two switching positions.
• 5.3 kg, 24 VDC solenoid, connector 3-pole (2 + PE) to EN 175301-803.

Applications

The article protects power units in production lines, workshops and test fields where several shifts work on the same machine. The setting is fixed during commissioning and then covered by the cap. NBR seals and HL hydraulic fluid match mineral oil operation.
