Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-06B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 450mm stroke and a built-in 4M210-06 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-06B
The AirTAC SAIF32X450S-06B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5-port 2-position solenoid valve. This integrated valve provides an effective flow area of 14.0 mm2 (Cv 0.78) and routes air directly to the 32mm bore, yielding 402N of push force at 0.5 MPa. Wired for DC24V via a terminal connection, the coil consumes 3.0W and carries an IP65 rating. The manifold links the valve to the cylinder using O8xO5 PU tubing, meaning the 1/8 valve port and 1/8 cylinder port are kept distinct.
Because the built-in valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This unit includes a magnet for CMSE reed and DMSE electronic sensors.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-06B Is Used
Decentralized Stations
Ideal for large machines with distributed I/O, removing long air lines back to a central valve island.
Compact Assembly
Fits space-tight cells where mounting a separate valve and cylinder separately is impossible.
Retrofit Upgrades
Drops into existing ISO 15552 footprints while adding local 5/2 valve control via a DC24V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-06B the Right Choice?
Choose this self-valved SAIF32X450S-06B when decentralized stations need to eliminate remote valve plumbing and cut panel space; one DC24V signal drives the actuator directly. If your application requires more push force at 0.5 MPa, step up to the 40mm bore which provides 628N. For this 450mm stroke, which exceeds 300mm, add an external guide to prevent rod side-loading and premature seal wear. Remember the 5/2 valve routes air but does not lock the load; for true position holding, select a SAIL lock cylinder. Replacement matches require bore 32, stroke 450, valve port 06, DC24V, terminal entry, PT thread, and the -S magnet.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-06B FAQ
The 32mm bore generates 402N push and 345N pull at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) and a max frequency of 5 cycles/sec.
No, the 5/2 valve routes air but does not lock the load; it holds position via pilot pressure only. The factory setting retracts the rod when the DC24V coil energises, but you can reposition the valve to extend-when-energised.
