The Bosch Rexroth DR 6 DP1-54/210YM (R900475604) is a direct operated, 3-way pressure reducing valve designed for precise pressure control in hydraulic systems. This valve is engineered for subplate mounting with a porting pattern according to ISO 4401-03-02-0-05 standards, ensuring interchangeability and ease of installation. It functions by reducing the pressure in port P1 to a set, lower level. This specific model includes an integrated check valve for free return flow from the actuator to the tank and a G1/4 pressure gauge connection for easy monitoring of the reduced pressure. Its robust construction guarantees reliable performance and a long service life in demanding industrial applications.
