Airtac M3B Basic Type Mechanical Valve M3B21006
A cropped merino wool cardigan taken up a notch, thanks to the flecks of metallic thread throughout. We love it even more paired with the matching sweater-pants.
2. The M3B, M3R, and M3L series utilize external mechanical actuation force, enabling position sensing or integration with limit switches;
3. M3C, M3D, M3Y, M3PF, M3PM, M3PP, M3PL, and M3HS series feature manual operation with diversified control head configurations for versatile application scenarios;
4. Spool-type structure ensures consistent actuation force independent of working pressure (zero back-pressure effect). Internal sealing rings provide leak-tight performance and responsive switching;
5. Lubrication-free operation;
6. Multi-position mounting capability for flexible installation;
7. M3C, M3D, M3Y, M3R, and M3I series incorporate metallic control heads for extended service life and enhanced operational reliability.

- Pneumatic fixture controls in welding stations
- Manual override for automated production lines
- Dust collector valve sequencing
- Agricultural equipment pneumatic controls
- Railway braking system prototypes
Installation note:
Lubricate pivot points with ISO VG32 hydraulic oil monthly.
For horizontal mounting, ensure lever movement plane aligns with
operator position. Maximum side load on lever: 15N.
Critical detail:
Requires 5-10 cycle "break-in" period before full load operation.
Not compatible with phosphate ester-based fluids.
