Pressure Relief Valve DBW30A2-5X/315XYUS6SMG24N9K4B12 - Bosch Rexroth R901546022

At 650 l/min a pressure relief valve decides how high a spike inside a power unit climbs. The pilot-operated poppet valve DBW30A2-5X/315XYUS6SMG24N9K4B12 in size 32 limits pressure across 2 to 315 bar and is rated for a maximum operating pressure of 350 bar.

Benefits

• Pressure adjustment range 2 to 315 bar at a maximum of 350 bar operating pressure.
• Up to 650 l/min across two ports to connection diagram ISO 6264-10-17.
• Pilot-operated poppet design seals tight instead of leaking past a spool.
• Internal hexagon with protective cap secures a set pressure against tampering.
• Two switching positions to spool symbol A on 24 VDC with a 3-pole connector (2 + PE).

Application

It sits in a pressure line of large power units, for example on presses, press lines and test rigs. Solenoid actuation lets a control system call up a set pressure without manual adjustment. A poppet design keeps a circuit tight through long holding periods.
