Product Overview
The Rexroth ZDR6DA2-46/150YM is a direct-operated, three-way pressure reducing valve designed for precise secondary circuit pressure regulation in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve belongs to the proven ZDR6 series, which is engineered to maintain a constant reduced outlet pressure regardless of fluctuations in the primary system pressure or changes in flow demand. The “DA” designation indicates a direct-operated pressure reducing function with a pressure gauge connection port, while the “2” specifies the pressure adjustment spring range. The “46” denotes the nominal size (NG6 / CETOP 3 mounting pattern), and “150YM” identifies the pressure rating and adjustment type. This valve is a critical component in circuits requiring a stable, lower-pressure branch derived from a higher-pressure main supply, such as clamping, pilot, or control circuits.
