Pressure Relief Valve DBW25BG2-5X/315YS6EG24N9DLR12 - Bosch Rexroth R900933835

Protecting a pump that delivers up to 500 l/min while unloading the circuit electrically calls for a pilot-operated relief valve of this rating. The DBW25BG2-5X/315YS6EG24N9DLR12 covers a setting range of 3.8 to 315 bar at 350 bar maximum operating pressure. It is a threaded connection valve to mounting pattern ISO 6264-08-13 in size 25 with a weight of 6.54 kg.

Benefits

• Setting range 3.8 to 315 bar, maximum operating pressure 350 bar
• Flow up to 500 l/min in size 25
• Threaded connection to mounting pattern ISO 6264-08-13 with 3 ports
• Electrical unloading through the built-on directional spool valve, spool symbol B with 2 switching positions
• 24 VDC solenoid, cable gland on a 3-pole connector (2 + PE) to EN 175301-803
• Poppet seat design with NBR seals rated to HL hydraulic fluid, weight 6.54 kg

Applications

A typical place is the pressure protection of a pump station whose circuit has to be relieved between cycles. The built-on directional spool valve at 24 VDC switches the system to zero pressure while the pump keeps turning. Set the pressure at the internal hexagon under the protective cap, then rate piping plus fittings to 500 l/min at 350 bar.
