The DA6VA2A5X/350FSM pressure cut-off valve belongs to the DA Pressure Cut-Off Valves series from Bosch Rexroth and interrupts pump delivery when circuit pressure exceeds an adjustable limit. The valve is built in size 6, matching compact manifolds that handle moderate flow rates. Subplate mounting simplifies removal because the body lifts off a manifold without disturbing pipework. The ISO 5781-03-04-0-00 porting pattern matches standard subplates so replacement parts remain interchangeable. Pump flow enters through channel A, ensuring the cut-off function monitors the main supply line. The adjustment is on Side A, letting technicians reach the setting screw from the same face used for pressure gauges. A sleeve with a hexagon head and a protective cap forms the adjustment mechanism, giving both wrench access and tamper protection. The pump line sees a maximum operating pressure of 350 bar, while the tank port is limited to 200 bar to protect return components.
Continuous hydraulic delivery up to 40 l/min can pass through the DA6VA2A5X/350FSM without exceeding its nominal flow rating, supporting medium-duty pump outputs. Port A withstands 350 bar, allowing the valve to control cylinders that operate at full system pressure, whereas the pilot line identified as port Y is limited to 100 bar to safeguard control passages. An NBR seal set is fitted so the unit remains compatible with conventional mineral oil fluids used in mobile and industrial power units. The permitted fluid temperature spans from -30 °C to 80 °C, which covers cold starts and high-load running conditions without compromising elastomer life. The valve can be installed in any position, simplifying manifold layout when space is restricted. A mass of 2.2 kg keeps manual handling straightforward during service exchanges. These characteristics complete the functional envelope that supports reliable pressure cut-off duty in compact hydraulic assemblies.
