Product Description
Rexroth Type SEW6 Series Leak-Free Directional Seat Valves
Product Overview: The SEW6 Series is a direct-operated, solenoid-actuated directional seat valve designed for high-performance hydraulic systems. Unlike traditional spool valves, the SEW series utilizes a ball or poppet sealing principle to ensure leak-free switching positions. Engineered for ultra-high pressure environments up to 420 Bar (6,000 PSI), it is the premier choice for pressure-holding applications, extended load-holding, and leakage-sensitive operations.
This category features three essential configurations: the 3/2-way M-3SEW6C and M-3SEW6U, and the 4/3-way M-4SEW6D. The entire range is equipped with DC24V wet-pin solenoids, ensuring an exceptionally long service life in harsh industrial environments.
Key Technical Advantages:
Absolute Leak-Free Sealing: The seat valve architecture provides perfect sealing in the closed position, preventing actuators (such as cylinders) from drifting under load.
420 Bar High-Pressure Rating: Ruggedly constructed to handle pressures up to 420 Bar, exceeding the limits of standard directional spool valves.
Wet-Pin Solenoid Technology: The solenoid armature operates fully immersed in oil, providing self-lubrication and damping for smooth, quiet switching and superior heat dissipation.
Manual Override Included: Comes standard with the N9 manual override button, allowing for system commissioning or emergency operation during power outages.
