Pressure Relief Valve DB52P2-3X/100XYU - Bosch Rexroth R900979858

The DB52P2-3X/100XYU pressure relief valve is set through an internal hexagon with a protective cap and is therefore secured against unintended adjustment. The setting range runs from 4 to 100 bar and flow reaches 2000 l/min.

Benefits

• Setting range 4 to 100 bar for circuits with low system pressure
• Internal hexagon with protective cap secures the setting
• Up to 2000 l/min flow at 315 bar maximum operating pressure
• Pilot-operated seat valve with low leakage when closed
• Subplate mounting in size 52 with two ports
• NBR seals for HL hydraulic fluid, weight 27.45 kg

Application

The valve protects pumps and consumers of large power units against overpressure, for example in presses, forges and test rigs. It mounts on a size 52 subplate. Hydraulic actuation of the main poppet comes from the pilot stage, so no electrical supply is needed for the relief function.

Manufacturer

Bosch Rexroth lists the valve as material number R900979858 in product family DB(W)52.
