Pressure Relief Valve DBW30A2N5X/135-6EG24N9K4E - Bosch Rexroth R901454523

Preload and blank holder circuits need only a fraction of the system pressure but often the full flow. This size 32 version is therefore limited to a setting range of 4 to 135 bar and still discharges up to 580 l/min.

Benefits

• Setting range 4 to 135 bar for preload, blank holder and auxiliary circuits
• 580 l/min rated flow despite the narrow pressure window
• 350 bar maximum operating pressure of the body protects against peaks from the main circuit
• Spool symbol A, pilot-operated poppet valve with internal hexagon and protective cap
• 6.85 kg weight, subplate mounting to ISO 6264-10-17

Applications

The valve is built into blank holder and preload circuits of presses and into auxiliary circuits of large power units. The narrow setting range allows more accurate adjustment than a spring spanned to 350 bar would permit. The circuit is unloaded electrically at 24 V.
