The Bosch Rexroth DA6VA2A5X/200FSV (R901184165) is a sophisticated pilot-operated pressure cutoff valve designed for precise control in hydraulic systems. This valve enables the regulation of pump flow between an actuator and a tank, ensuring efficient operation and energy savings. It features an adjustable switching pressure differential, allowing customization to specific system requirements. The main components include a pilot control stage, main stage screw-in cartridge valve, check valve, and housing. The DA6VA2A5X/200FSV operates by introducing pump flow into the system's accumulator via port B. When the pressure at port B surpasses the set top switching pressure, it triggers the pilot control valve to open, enabling discharge through port A Y while simultaneously closing the connection from B to P. This action diverts the pump flow to a depressurized circulation from P to T. Additionally, this model supports subplate mounting with a porting pattern that is not fully compliant with ISO standards and may be ordered without a locating hole. Subplates are required as a separate order. For adjustments, it features a sleeve with hexagon and protective cap for easy access and modification of settings. The switching pressure differential is adjustable between approximately 5% to 20% of the nominal value. This specific model of Bosch Rexroth's pressure cutoff valve is particularly suitable for applications requiring reliable switchovers from pump-to-actuator operations to pump-to-tank circulations within hydraulic systems. It ensures that when pressures exceed or drop below certain thresholds, the hydraulic flow is redirected appropriately to maintain system integrity and performance. The DA6VA2A5X/200FSV's adaptability makes it an essential component in advanced hydraulic installations where precise pressure modulation is critical for optimal functionality.
