Product Description
Rexroth R900597546 DZ20-1-53/200
The Rexroth R900597546 DZ20-1-53/200 is a pilot-operated pressure relief valve designed to limit the pressure in a hydraulic system. It consists of a main valve with a main spool assembly and a pilot control valve with a pressure adjustment element. This valve is used to protect hydraulic components from excessive pressure by diverting flow to the tank when the set pressure is reached. It is designed for subplate mounting according to ISO 6264 standards, ensuring reliable performance and system safety.
