Pressure Relief Valve DBW52BP1-3X/315XYU6EG24N9K4 - Bosch Rexroth R901105876

A power unit moving very high oil volumes needs relief protection that does not become the bottleneck when it opens. The DBW52BP1-3X/315XYU6EG24N9K4 limits pressure in pilot-operated design to a value set at the rotary knob between 4 and 315 bar, passing up to 2000 l/min.

Advantages

• Pressure adjustment range 4 to 315 bar, reset at the rotary knob without tools
• Flow up to 2000 l/min, sized for power units running several pumps
• Pilot-operated seat valve, operating pressure up to 315 bar
• Solenoid actuation 24 V DC with two switching positions, wired through a connector, 3-pole (2 + PE) according to EN 175301-803
• Subplate mounting in size 52, NBR seals for HL hydraulic fluid

Applications

Typical installations are power units of presses, rolling mills and test rigs carrying 2000 l/min at up to 315 bar. The rotary knob suits plants where the limit is changed more often during operation. Spool symbol B defines the behaviour of the two switching positions. The NBR seals match HL hydraulic fluid.
