Pressure Relief Valve DBW 30 AG2-5X/315Y6EG24N9K4/12 - Bosch Rexroth R978021247

When back pressure builds up in the return line, the pilot stage should not drain into that same line. This version adds a third port for exactly that, uses symbol A and limits up to 650 l/min in size 32 to a value between 3.8 and 315 bar.

Advantages

• Three ports, allowing a separately routed pilot drain
• Symbol A, solenoid unloading on 24 VDC, two switching positions
• Setting range 3.8 to 315 bar, maximum operating pressure 350 bar
• Flow up to 650 l/min, connection diagram ISO 6264-10-17
• Threaded connection, 6.5 kg, NBR seals for HL hydraulic fluid

Application

The three port build is needed on systems with a return filter or cooler, where residual pressure stands in the tank line. A separate drain keeps the pilot circuit clear of it. In every other respect the valve caps pressure in the pump line as usual.
