Pressure Relief Valve DBW10B2-5X/200YS6EG24N9K4R12E - Bosch Rexroth R901171936

As the pump capacity of a power unit grows, the pressure relief valve has to be able to discharge the full flow. This size 10 version is rated for 230 l/min instead of 200 l/min and covers a setting range of 4 to 200 bar.

Benefits

• 230 l/min rated flow, so larger pumps are fully protected
• Setting range 4 to 200 bar at 350 bar maximum operating pressure
• Pilot-operated poppet valve, spool symbol B with two ports
• Internal hexagon with protective cap holds the pressure stage
• 5.16 kg weight, subplate mounting to ISO 6264-06-09

Applications

The valve is fitted as the main protection in power units whose pump delivery exceeds 200 l/min. At flows of this size the discharge capacity decides how far pressure overshoots when the valve opens. Electrical unloading is by a 24 V DC solenoid.
