Pressure Relief Valve DB52F3-3X/315XU - Bosch Rexroth R900448120

The DB52F3-3X/315XU pressure relief valve protects high-flow hydraulic circuits and holds system pressure at the preset value. Built as a pilot-operated poppet seat valve in size 52, it passes up to 2000 l/min at a maximum operating pressure of 315 bar.

Benefits

• Flow up to 2000 l/min through the size 52 flange connection
• Setting range 3.9 to 315 bar on a lockable rotary knob with scale
• Pilot-operated poppet seat design keeps leakage low in the closed position
• Three ports and hydraulic actuation across two switching positions
• NBR seals for HL hydraulic fluid, installed weight 27.2 kg

Application

The valve safeguards presses, power units and large cylinder circuits against pressure overshoot. A range up to 2000 l/min suits power units running several pumps or large accumulator circuits. The mating face has to match the size 52 flange connection.
