The Rexroth R900597233 is a pilot-operated pressure reducing valve of the DR 20 series, designed for subplate mounting. Its primary function is to reduce the operating pressure in a specific section of a hydraulic system. This model is engineered to maintain a constant, reduced pressure at the outlet (port A), regardless of fluctuations in the main system pressure (port P), as long as the main pressure remains higher than the set secondary pressure. The valve includes an integrated check valve, allowing for free return flow from port A to port B. This specific version comes with an external pilot oil drain (Y port) and a maximum pressure setting of 200 bar.
