Pressure Relief Valve DBW 25 BG2-5X/315-6EG24N9K4/12 - Bosch Rexroth R978916709

Size 25 covers the mid power range where 500 l/min are moved and two functions are needed at once: a firm pressure limit between 3.8 and 315 bar and an electrical unloading path. This pilot-operated valve provides both, the unloading running through a mounted directional spool valve on 24 VDC.

Advantages

• Flow up to 500 l/min, maximum operating pressure 350 bar
• Adjustment from 3.8 to 315 bar behind an internal hexagon with protective cap
• Solenoid unloading on 24 VDC with two switching positions
• Connection diagram ISO 6264-08-13, threaded connection with two ports
• Poppet seat pressure stage at 5.1 kg installed weight
• NBR seals, HL hydraulic fluid, connector 3-pole (2 + PE) to EN 175301-803

Application

The valve normally sits in the pump line of power units, machine tools and test rigs. Energising the coil drops the line to tank level so the pump keeps turning without load. That saves drive power during the pauses between two working cycles.
