Airtac M3R Roller Lever Type Mechanical Valve M3R21008
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.

High-sensitivity mechanical valve featuring a multi-position roller lever for precise actuator control. The hardened stainless steel roller reduces wear during repeated operation, while the dual-spring mechanism ensures positive reset. Designed for both horizontal and vertical installations with optional lever angles (90°/180° configurations available).
- Cartesian robot end effector positioning
- Conveyor belt emergency stop systems
- Assembly line workpiece detection
- Packaging machine limit switching
- Automated door safety interlocks
Installation note:
Align roller contact surface within 2° of actuator movement axis. Lubricate pivot point every 50,000 cycles using silicone-free grease (ISO VG 32 equivalent). Avoid side-load forces exceeding 5N on lever arm.
