Product Overview
The Rexroth ZDR10DA2-5X/150Y (Material No. R900410884) is a direct-operated, pilot-assisted pressure reducing valve from the proven ZDR10 series, engineered for precise secondary circuit pressure regulation in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve maintains a constant reduced outlet pressure regardless of fluctuations in the primary (inlet) pressure or changes in flow demand. The “DA” designation indicates a direct-operated pressure reducing function with a pressure relief capability on the secondary side, while the “150Y” specification denotes a 150 bar pressure rating with a specific adjustment and spring configuration. The valve is part of the 5X series (component series 50), ensuring long-term availability and compatibility with the global Rexroth modular valve platform. It is designed for subplate mounting in accordance with ISO 4401 and CETOP standards, making it a direct drop-in replacement for OEM installations in demanding industrial environments.
