Pressure Relief Valve DBW30B2N5X/305Y6EG24N9K4E - Bosch Rexroth R901348749

The higher the setting pressure, the more a valve has to discharge the flow without becoming a restriction. This pilot-operated pressure relief valve works across a setting range of 4 to 305 bar and discharges up to 700 l/min through its subplate connection.

Benefits

• Setting range of 4 to 305 bar, so high-pressure stages are protected without an additional valve.
• 700 l/min maximum flow, matched to the larger pump outputs found in size 32 circuits.
• Maximum operating pressure of 350 bar, leaving headroom above the top setting value.
• Seat valve design for tight closing and low leakage while pressure is held.
• Internal hexagon under a protective cap keeps the adjusted value out of reach.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.

Application

Suited to presses, forging lines and large power units working above the common 200 bar stage. The high permitted flow fits circuits fed by several pumps or by accumulators. The solenoid drops the system to zero pressure during setup pauses, which cuts heat input and pump load.
