Pressure Relief Valve DBW 25 BG2-5X/315X6EG24N9K4/12 - Bosch Rexroth R978013502

Back pressure in the tank line falsifies the value that was dialled in. This size 25 version therefore routes the pilot drain out through a third port and keeps the limit between 3.8 and 315 bar steady even at 500 l/min.

Advantages

• Third port for a separately routed pilot drain
• Setting range 3.8 to 315 bar, maximum operating pressure 350 bar
• Flow up to 500 l/min, connection diagram ISO 6264-08-13
• Solenoid unloading on 24 VDC through a mounted directional spool valve
• Internal hexagon with protective cap, 6.5 kg, NBR seals for HL fluid

Application

It belongs on power units with a return filter, a cooler or long tank lines. Residual pressure builds up there and should not reach the pilot circuit. Otherwise the valve performs the classic protection duty in the pump line.

Manufacturer

Bosch Rexroth lists the build under material number R978013502, product family DB.10-30. Port allocation and curves are covered by the data sheet.
