Pressure Relief Valve DBW52BP1-3X/315U6EG24N9DL - Bosch Rexroth R901408456

Relief pressure is usually readjusted several times while a plant is being run in. The DBW52BP1-3X carries a rotary knob instead of an internal hexagon and limits pressure steplessly from 4 to 315 bar at up to 2000 l/min.

Benefits

• Rotary knob for pressure setting - the set point can be corrected without a tool.
• Adjustment range 4 to 315 bar with a maximum operating pressure of 315 bar.
• 2000 l/min maximum flow through size 52.
• Pilot-operated seat valve - it seals better when closed than a spool design.
• Solenoid actuation on 24 VDC, 2 switching positions, wired through a cable gland.

Application

It belongs at the pump outlet of large power units, where it caps system pressure and unloads the pump electrically to tank when required. The rotary knob wins wherever pressure is trimmed during operation. Where unauthorised adjustment has to be ruled out, the version with an internal hexagon and protective cap is the better fit.
