Pressure Relief Valve DBW30B2N5X/50YS6EG24N9K4R12E - Bosch Rexroth R900788020

A low-pressure circuit with a large circulating flow has to be limited just below 50 bar. The DBW30B2N5X provides the range of 4 to 50 bar with 700 l/min of relief capacity.

Benefits

• Adjustment range of 4 to 50 bar for circuits at low working pressure.
• 700 l/min of flow without forcing the setting upwards.
• Size 32 with subplate mounting to ISO 6264-10-17.
• Spool symbol B, two switching positions, 24 V DC solenoid actuation.
• Internal hexagon with protective cap for a secured fine setting in the lower pressure band.
• 7.1 kg, NBR seals, HL hydraulic fluid.

Technical data

Applications

Low settings at high throughput occur in cooling and flushing circuits, circulating lubrication and prefill circuits of large presses. Fine adjustment through the hexagon helps to hit a value below 50 bar. The body itself is rated for 350 bar of operating pressure.
