Pressure Relief Valve DBW10BG2-5X/180-6EG24N9K4E - Bosch Rexroth R901397961

A hydraulic accumulator only pays off if the pump is genuinely unloaded between charges. The DBW10BG2-5X/180-6EG24N9K4E handles both tasks: it limits pressure across 4 to 180 bar and unloads through a built-on directional spool valve.

Benefits

• Solenoid unloading via a built-on directional valve, the pump delivers without pressure during a pause.
• Adjustment range 4 to 180 bar at a maximum operating pressure of 350 bar.
• Up to 200 l/min flow in size 10, symbol B.
• Threaded connection, the valve is piped in directly.
• Pressure valve in poppet seat design with an internal hexagon under a protective cap.
• 4.88 kg weight, NBR seals for HL hydraulic fluid.

Applications

Typical circuits are accumulator charging schemes in presses, clamping systems and tool changers. The solenoid gives the control system a simple way of stopping the pump between two charging cycles. An adjustment range up to 180 bar suits accumulators with a matching pre-charge.
