Product Overview

The SR551-DN2※R is a 5/2-way solenoid-controlled spool valve designed for directional flow control in pneumatic or hydraulic systems. Featuring a spool mechanism driven by electromagnetic coils, it enables swift and reliable switching between two positions, each offering distinct flow paths (five ports in total) to regulate actuator movements.

Constructed with corrosion-resistant materials, this valve suits diverse industrial environments, particularly scenarios requiring frequent switching or continuous operation. Its compact design facilitates integration into automated systems, making it applicable in machinery manufacturing, chemical processing, energy sectors, and more. Modular components allow flexible installation via multiple piping configurations.

The SR551-DN2※R excels in stability across low to medium pressure ranges, with moderate fluid cleanliness requirements. The low-power electromagnetic drive contributes to energy efficiency. Its robust sealing and smooth spool movement ensure consistent performance, while simplified maintenance aligns with long-term operational needs. The valve’s versatility and reliability support complex fluid control tasks without compromising system responsiveness.167
