Pressure Relief Valve DBW25BG2-5X/350S6EG24N9K4R12V - Bosch Rexroth R901542947

NBR reaches its limit at high oil temperature and with fluids carrying aggressive additives. The DBW25BG2-5X/350S6EG24N9K4R12V is therefore built with FKM seals, covers the adjustment range from 3.8 to 350 bar in size 25 and relieves up to 500 l/min when it opens.

Benefits

• FKM seals for service at higher oil temperatures than NBR versions allow.
• Adjustment range 3.8 to 350 bar across the full operating pressure of the size.
• Internal hexagon with protective cap, the setting stays protected against accidental change.
• 500 l/min relief flow with connection diagram ISO 6264-08-13.
• Threaded connection and 6.6 kg, solenoid unloading through a built-on directional spool valve.

Application

The valve is used in press and power unit circuits that run close to rated pressure for long periods and heat up in the process. Threaded connection allows installation straight into the pressure line, so no subplate has to be machined. The solenoid switches the circuit to unloaded circulation as soon as the cycle permits.
