Product Overview
The Rexroth ZDR6DP2-4X/25YM (Material No. R900483785) is a direct-operated, three-way pressure reducing valve from the proven ZDR6 series, designed for precise secondary 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 “DP2” designation indicates a direct-operated pressure reducing valve with a pressure gauge connection port, while the “4X” series identifier reflects the current production generation with standardized, interchangeable mounting dimensions. The “25YM” suffix specifies a pressure rating of 25 bar and a specific adjustment and spring configuration. This valve is a compact, cartridge-style component widely used as a reliable pressure-limiting and pressure-reducing element in demanding hydraulic circuits.
