Pressure Relief Valve DBW30B2N5X/50US6SMG24N9K4B12 - Bosch Rexroth R901201435

Limiting a circuit to 30 or 40 bar calls for a matching spring, otherwise a setpoint sits at a lower stop. The pilot-operated poppet valve DBW30B2N5X/50US6SMG24N9K4B12 in size 32 covers 2 to 50 bar and relieves up to 650 l/min while doing so.

Benefits

• Pressure adjustment range 2 to 50 bar for fine resolution at low pressure.
• Up to 650 l/min in size 32 to ISO 6264-10-17.
• Spool symbol B in two switching positions with 24 VDC solenoid actuation.
• Poppet design with internal hexagon and protective cap for a secured setting.
• 7.16 kg, NBR seals for HL fluid up to a maximum operating pressure of 350 bar.

Application

Valves like this protect circuits working far below system pressure, such as clamping and holding circuits or prefill stages on presses. A narrow adjustment range allows a precise setting, so a small turn of an adjuster does not shift pressure by many bar.

Manufacturer

Bosch Rexroth lists this pilot-operated pressure relief valve DBW30B2N5X/50US6SMG24N9K4B12 under material number R901201435.
