Pressure Relief Valve DBW 10 B3-5X/315-6EG24N9K4V/12 - Bosch Rexroth R978917107

At raised oil temperatures or with aggressive hydraulic fluids, NBR seals reach their limit. The pilot-operated pressure relief valve DBW 10 B3-5X/315-6EG24N9K4V/12 in size 10 is therefore sealed with FKM and limits adjustably from 4 to 315 bar.

Benefits

• FKM seals for applications with raised temperature demands.
• Lockable rotary knob with scale, the setting stays readable and secured against adjustment.
• Adjustment range 4 to 315 bar at a maximum operating pressure of 350 bar.
• 250 l/min through the size 10 port pattern ISO 6264-06-09.
• 4.3 kg, poppet seat pilot stage, electrical unloading at 24 VDC to symbol B.

Technical data

Applications

In works with high ambient temperature, or in plants run on fire-resistant fluids for safety reasons, the sealing material decides service life. FKM keeps its shape where NBR hardens and starts to leak. Pairing it with a lockable rotary knob suits installations whose limiting pressure has to be checked and documented.
