Pressure Relief Valve DBW30BG3-5X/315S6EG24N9K4R12 - Bosch Rexroth R901209275

This build of the pilot-operated relief valve goes straight into the line through a threaded connection and needs no subplate. It limits pressure across 3.8 to 315 bar, relieves up to 650 l/min and can be unloaded electrically through the mounted directional spool valve.

Benefits

• Threaded connection, so the valve fits into the line without a subplate
• Adjustment range of 3.8 to 315 bar at a maximum operating pressure of 350 bar
• 650 l/min relief capacity to the ISO 6264-10-17 interface
• Electrical unloading through a mounted directional spool valve at 24 VDC
• Pressure valve in poppet seat design with a lockable scaled rotary knob
• NBR seals for HL hydraulic fluid, weight 7.04 kg

Applications

The valve protects power units that have no control manifold and are piped directly. With the mounted unloading stage the pump runs against low pressure at standstill, which cuts drive power and oil heating. The adjustment range starts at 3.8 bar and reaches 315 bar.
