Pressure Relief Valve DBW30B2N5X/80Y6EG24N9K4E - Bosch Rexroth R901076576

When a large pump feeds pressure-sensitive components, the relief stage has to be set low and still swallow the full flow. This pilot-operated pressure relief valve caps pressure from 4 to 80 bar and accepts up to 700 l/min.

Benefits

• Setting range of 4 to 80 bar, so the whole scale sits in the protection band of sensitive consumers.
• 700 l/min permitted flow, so the full delivery drains away without a pressure rise.
• Internal hexagon under a protective cap secures the low ceiling.
• Pilot-operated seat valve that closes tightly in the rest position.
• Maximum operating pressure of 350 bar as the body limit.
• 6.48 kg weight with solenoid actuation at 24 VDC.

Application

Suited to prefill circuits, cooling and flushing lines and accumulator charging circuits with a low pressure limit. The low setting protects components sharing the same power unit. During pauses the solenoid drops the circuit to zero pressure, with approval for HL hydraulic fluid and NBR seals.
