The DAW10B2-5X/100-10Y6EG24N9K4 valve belongs to the DA Pressure Cut-Off Valves series from Bosch Rexroth and interrupts flow once system pressure reaches a preset limit in hydraulic automation loops. It uses size 10 porting. A normally open symbol keeps the passage open until the control coil is energized, after which flow is blocked to protect downstream components. The high-power 6E solenoid provides quick spool movement, and its winding is rated for 24 V DC to match common control circuits. Wiring is completed through a DIN EN 175301-803 K4 plug. Pressure is set by a spindle with a protective cap that shields the adjuster. A concealed manual override allows local shifting without exposing moving parts. The design maintains a 10 % switching pressure differential between opening and closing thresholds, and the assembly weighs 5.3 kg.
In operation the unit tolerates 315 bar at port P, while a 100 bar limit applies both as the general pressure setting and as the maximum for ports t and Y, protecting the tank and pilot returns. It passes up to 40 l/min, matching common power units. Pilot oil is returned externally through port Y, which prevents back-pressure from influencing the control stage. Hydraulic media must be mineral oil of type HL or HLP as defined in DIN 51524, and the circuit must maintain cleanliness better than ISO 4406 class 20/18/15 to avoid spool sticking. Contaminant particles that exceed this limit can accelerate wear on the metering edges, so filtration is critical. These flow and fluid conditions allow the valve to maintain stable performance in automation manifolds.
