Product Description

Rexroth R900597048 DR20-5-52/315Y

The Rexroth R900597048 DR20-5-52/315Y is a pilot-operated pressure reducing valve designed to maintain a consistent, lower pressure in a specific part of a hydraulic system, irrespective of higher and fluctuating inlet pressures. This valve is built for subplate mounting with a porting pattern according to ISO 6264. The DR20 series is known for its reliability and precision in controlling hydraulic pressure. The ‘Y’ designation in the model code signifies an external pilot oil drain, which can be beneficial in certain circuit designs to prevent pressure build-up in the spring chamber.
