Product Description

Rexroth ZDR10DP1-5X/210YM

The Rexroth ZDR10DP1-5X/210YM is a 3-way direct operated pressure reducing valve in a sandwich plate design, nominal size NG10. It is engineered to reduce system pressure and maintain a constant lower pressure at the outlet (port A). This valve features a pressure relief function for the secondary circuit, meaning if the pressure in port A exceeds the set value, fluid is relieved to the tank port (Y). The pressure setting is adjustable up to 210 bar. This specific model, ZDR10DP1-5X/210YM, includes an external pilot oil drain (Y) and is configured without an integrated check valve (M). It belongs to the 5X component series, ensuring standardized installation and connection dimensions according to ISO 4401-05-04-0-05.
