Pressure Relief Valve DBW30B2N5X/110Y6EG24N9K4E - Bosch Rexroth R901027861

A low-pressure circuit with high delivery places heavy demands on the flow capacity of its relief stage. This pilot-operated pressure relief valve accepts up to 700 l/min and caps pressure across a range of 4 to 110 bar.

Benefits

• Setting range of 4 to 110 bar, matched to consumers with limited pressure rating.
• 700 l/min permitted flow, so the full delivery drains away without a pressure rise.
• Internal hexagon under a protective cap secures the ceiling against adjustment.
• Pilot-operated seat valve that closes tightly in the rest position.
• Maximum operating pressure of 350 bar as the body limit.
• 6.5 kg weight with electrical unloading at 24 VDC.

Application

A fit for prefill and flushing circuits, cooling systems and low-pressure supplies driven by a high-output pump. The low ceiling protects components running in the shared circuit. During pauses the solenoid unloads the circuit, with NBR seals for HL hydraulic fluid.
