The Bosch Rexroth DA6VA2B5X/350FSM (R901224228) is a sophisticated pressure valve designed for versatile hydraulic applications. This pilot-operated pressure cutoff valve features an adjustable switching pressure differential, enabling precise control over hydraulic system pressures. The main components of this valve include a pilot control stage, a main stage of the screw-in cartridge valve, a check valve, and a robust housing. The DA6VA2B5X/350FSM operates by directing pump flow from port P to the accumulator or actuator through port B. When the pressure at port B surpasses the preset top switching pressure, the pilot control valve triggers, allowing fluid discharge via port A Y and causing the check valve to shut off the connection from B to P. This action switches the pump flow to a depressurized circulation from P to T. This model supports subplate mounting with a porting pattern that follows ISO standards but does not comply entirely with them; it can also be used without a locating hole. Subplates are required for mounting and must be ordered separately. The adjustment mechanism is designed as a sleeve with hexagon and protective cap, providing secure pressure settings that can be locked in place with a clamping screw and lock nut. The DA6VA2B5X/350FSM allows for an adjustable switching pressure differential ranging from approximately 10% to 100% of the nominal value, ensuring adaptability for different system requirements. It is important to note that this valve does not directly provide pressure limiting functions but achieves this indirectly through its check valve and control line in the actuator channel. Overall, Bosch Rexroth's DA6VA2B5X/350FSM offers reliable performance and precise control for hydraulic systems requiring efficient flow direction and pressure regulation.
