Pressure Relief Valve DBW 30 B2-5X/350U6EG24N9K4/12 - Bosch Rexroth R978910643

A maximum operating pressure helps little if the setting range ends earlier. The pilot-operated pressure relief valve DBW 30 B2-5X/350U6EG24N9K4/12 reaches the permitted limit with 2 to 350 bar and relieves up to 650 l/min.

Benefits

• Setting range 2 to 350 bar, matching the maximum operating pressure.
• Up to 650 l/min in size 32 to port pattern ISO 6264-10-17.
• Subplate mounting, the channels stay inside the manifold.
• Internal hexagon with protective cap for a secured setting.
• 5.05 kg, NBR seals, symbol B, solenoid actuation at 24 VDC.

Application

Presses, punching units and clamping hydraulics use the upper pressure band to produce large forces from small cylinders. A setting range to 350 bar puts the valve on that operating point without changing the pressure spring. The solenoid unloads the circuit between strokes.
