Airtac M3R Roller Lever Type Mechanical Valve M3R21008G
2. The M3B, M3R, and M3L series utilize externally sourced actuation force for directional switching, enabling integration with position sensing or limit switch applications.
3. Manual-operated M3C, M3D, M3Y, M3PF, M3PM, M3PP, M3PL, and M3HS series feature diversified actuator head configurations for optimized adaptability across operational conditions.
4. Spool-type architecture ensures consistent control force independent of working pressure (zero backpressure influence). Internal ring sealing mechanism guarantees leak-tight performance and responsive directional switching.
5. Lubrication-free operation eliminates routine maintenance requirements.
6. Multi-position mounting compatibility enhances installation flexibility and system integration efficiency.
7. Metal actuator heads in M3C, M3D, M3Y, M3R, and M3I series ensure extended service life with reliable, stable performance under demanding conditions.
