Pressure Relief Valve DB52P2-3X/260UE - Bosch Rexroth R901398798

A pressure relief valve that should not be readjusted after commissioning needs a secured setting element. On the DB52P2-3X/260UE the adjustment is an internal hexagon behind a protective cap. It protects circuits carrying up to 1500 l/min, with a setting range from 4 bar to 260 bar at 315 bar permissible operating pressure.

Benefits

• Internal hexagon adjustment under a protective cap, secured against unintended changes
• Setting range from 4 bar to 260 bar at an operating pressure of up to 315 bar
• Flow up to 1500 l/min across the two ports of size 52
• Pilot-operated poppet valve, therefore a tight seal in the closed state
• NBR seals and HL hydraulic fluid, CE conformity
• 27 kg valve mass with subplate mounting

Application

The valve protects pump outlets and accumulator circuits in power units of medium to large rating. The version with a protective cap is chosen where several people work on the plant and the set limit pressure forms part of the safety assessment.
