Pressure Relief Valve DBW52BP2-3X/315XYU6EG24N9DL - Bosch Rexroth R900617195

The pilot stage of a large relief valve reacts badly to back pressure in the tank gallery. In the 315XYU6EG24N9DL version, the DBW52BP2-3X routes pilot oil and pilot drain through separate X and Y ports and works up to 315 bar.

Benefits

• Separate pilot ports X and Y - the pilot stage stays decoupled from pressure in the tank gallery.
• Up to 2000 l/min in size 52 at a maximum operating pressure of 315 bar.
• Adjustment range 4 to 315 bar through an internal hexagon with protective cap.
• Symbol B, 2 ports, 2 switching positions, solenoid actuation on 24 VDC.
• 28.66 kg, NBR seals, pilot-operated seat valve, subplate mounting.

Application

Intended for systems with long return lines or return filters, where the tank gallery builds up counter pressure. The Y port lets pilot flow reach tank unpressurised, which keeps the relief setting stable. Both galleries have to be provided in the manifold.
