Airtac CM3PF Flat Push Button Mechanical Valve CM3PF05B
1. CM3B, CM3L, CM3V, and CM3R series require external force for directional switching, suitable for position detection or limit switch applications.
2. CM3PF, CM3PM, CM3PMS, CM3PMX, CM3PL, CM3PP, CM3HS, CM3HD, and CM3Y series feature manual operation with multi-configuration actuator heads for diverse operational conditions.
3. Shut-off type structure ensures excellent sealing performance, responsive direction switching, and lubrication-free operation.
4. Multi-position mounting capability enables flexible installation configurations.
5. CM3L, CM3V, CM3R, and CM3Y series incorporate metal actuator heads for enhanced durability and operational stability.
6. CM3PMS and CM3PMX series integrate metal protective covers to safeguard button caps and prevent accidental activation from external forces.
