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.

• 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
