Pressure Relief Valve DBW30B2N5X/190-6EG24N9K4E - Bosch Rexroth R901039841

When the working point sits just below the 200 bar mark, a scale that ends right there helps. This pilot-operated pressure relief valve covers 4 to 190 bar and discharges up to 580 l/min through its subplate connection.

Benefits

• Setting range of 4 to 190 bar, so the working point is not at the end of the scale and can be trimmed more finely.
• Internal hexagon under a protective cap for a value that stays put.
• Pilot-operated seat valve with tight closing in the rest position.
• Maximum operating pressure of 350 bar above the scale.
• 5.7 kg weight at 580 l/min maximum flow.
• Electrical unloading at 24 VDC across two switching positions.

Application

Meant for machine tools, clamping hydraulics and power units whose process pressure sits just below 200 bar. The concealed adjustment keeps the value constant. The solenoid lets the circuit idle pressureless between cycles, with NBR seals for HL hydraulic fluid.
