Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm stroke and a built-in 4M210-08 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 SAIF32X250S-08B
The AirTAC SAIF32X250S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal coil consuming 3.0 W, it achieves an effective flow of Cv 0.89. While the cylinder body rates to 1.0 MPa, the built-in valve operates at 0.15-0.8 MPa, setting the practical working range for the assembly. The 32mm bore generates 402N push force at 0.5 MPa, making it ideal for compact actuation.
This unit switches itself from one coil signal, eliminating remote plumbing and saving panel space for decentralized stations. The manifold connects via an O8xO5 PU tube, and the valve port (1/4) differs from the cylinder port (1/8). Factory-set to retract when energised, the valve can be repositioned to extend on signal. The -S magnet works with 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)

|---|---|---|
| 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 SAIF32X250S-08B Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, cutting panel space and eliminating long valve tubing runs.
Compact Assembly
Fits space-tight machines where running separate remote valve plumbing is costly or physically impossible.
Retrofit Upgrades
Perfect for upgrading existing lines where adding a separate valve island would require extensive rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-08B the Right Choice?
Choose this self-valved SAIF unit when decentralizing a machine to cut tubing costs and panel space; it replaces a separate cylinder plus remote valve. The 32mm bore yields 402N push at 0.5 MPa—step up to the 40mm bore (628N push) if your load exceeds this. For stroke lengths at 250mm, ensure adequate guide support to prevent side-load damage. This assembly does not hold loads unpowered; for position holding, consider the SAIL lock cylinder. Replacement match: 32mm bore, 250mm stroke, 1/4 valve port, DC24V terminal entry, PT threads, with -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 SAIF32X250S-08B FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The integrated 4M210-08 5/2 valve provides an effective flow area of 16.0 mm2 (Cv 0.89).
The DC24V terminal coil consumes 3.0 W and activates in 0.05s. By default, the factory setting retracts the rod when energised, but you can reposition the valve to extend on signal. This eliminates the need for a separate remote valve.
