DAW30B2-5X/100-17-6EW110N9K4

The DAW30B2-5X/100-17-6EW110N9K4 belongs to the DA Pressure Cut-Off Valves series manufactured by Bosch Rexroth and is intended to interrupt hydraulic flow automatically once a preset pressure is reached. With size 32 porting it fits high-capacity manifolds, and subplate mounting lets technicians replace the unit without disturbing hard lines. Pressure is set through a spindle with a protective cap, which shields the adjustment screw from dirt and accidental movement. The unit is normally open so flow proceeds until the threshold is exceeded. A maximum flow rating of 240 l/min supports medium pump outputs while keeping pressure loss low. It tolerates 315 bar at port P, giving headroom above most working limits, whereas the internal pressure rating of 100 bar defines the cut-off level established in the type code. A switching pressure differential of 17 % prevents rapid cycling by ensuring reopening only after system pressure has fallen by the specified margin.

DIN EN 175301-803 wiring makes the electrical interface compatible with common machine connectors, allowing the pressure switch section to signal control systems without special adapters. ISO 4406 cleanliness class 20/18/15 requires users to maintain fluid filtration that limits particulate contamination, extending service life of the moving elements. Operation with mineral oil grades HL or HLP provides predictable lubrication and sealing characteristics, and temperatures may reach +80 °C without damaging elastomers. Viscosity can rise to 800 mm²/s, enabling start-up in cold environments without bypass arrangements. A concealed manual override lets maintenance staff cycle the valve mechanically in case of solenoid failure while keeping the control inaccessible during normal service. Port T/y is rated for 100 bar so the return line can handle residual pressure safely. The assembly weighs 15.0 kg, a factor that determines bracket strength and ease of handling during installation.
