The DA6VP2B5X/100FSM valve belongs to the DA Pressure Cut-Off Valves series and is manufactured by Bosch Rexroth for pressure-controlled hydraulic automation. It halts pump flow once a defined limit is reached, protecting downstream actuators. Mechanical actuation shifts the valve between its two switching positions without external pilot power. With a nominal size of 6, it integrates into compact manifolds that save space. Installation uses subplate mounting on the ISO 5781-03-04-0-00 interface, simplifying service. The pump connects through channel P, and discharged fluid leaves via pilot drain port A (Y). A pressure stage of 100 bar establishes the standard cut-off point for circuits that operate at moderate working pressures.
Adjustment is carried out on side B with a sleeve that includes a hexagon and cap, allowing technicians to alter the setpoint while the unit remains in place. NBR seals retain hydraulic media and resist wear. Approved fluids are HL, HLP, HLPD, HVLP, HVLPD, and HFC, giving compatibility with both mineral and water-glycol blends. The internal passages accommodate up to 40 l/min, supporting medium-flow pump outputs. The housing withstands a maximum operating pressure of 350 bar, providing ample margin above the 100-bar cut-off setting. These characteristics let the DA6VP2B5X/100FSM keep stable pressure control across varying temperatures, fluid types, and duty cycles.
