Pressure Relief Valve DBW20B2-5X/315S6EG24N9K4R12/12 - Bosch Rexroth R978898122

A power unit at 500 l/min is served by size 25 and saves the larger mounting block. Within that frame the pilot-operated poppet valve DBW20B2-5X/315S6EG24N9K4R12/12 limits pressure between 4 and 315 bar at a maximum operating pressure of 350 bar.

Benefits

• Up to 500 l/min in size 25 to connection diagram ISO 6264-08-13.
• Pressure adjustment range 4 to 315 bar, rated to a maximum of 350 bar.
• Spool symbol B in two switching positions with 24 VDC solenoid actuation.
• Internal hexagon with protective cap secures a pressure setting.
• 5.88 kg, NBR seals for HL hydraulic fluid.

Application

It is used on medium duty power units, for instance on presses, clamping systems and machine tools. A connector to EN 175301-803 simplifies assembly, while poppet design keeps a circuit tight at rest.
