Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 450mm stroke and a built-in 4M310-08 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 SAIF80X450S-08A
The AirTAC SAIF80X450S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. This integrated manifold block delivers a Cv of 1.40 and uses an O10 x O6.5 PU tube to bridge the valve to the cylinder. Driven by an AC220V terminal entry coil drawing 3.5 VA, it activates in 0.05 seconds or less. Because the valve operates at 0.15-0.8 MPa, the practical working pressure for the assembled SAIF unit is 0.15-0.8 MPa, even though the cylinder body itself rates to 1.0 MPa.
Providing 2513 N of push force and 2268 N of pull force at 0.5 MPa, this 80mm bore unit includes a -S magnet for position sensing with CMSE reed or DMSE electronic switches. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend upon energising. This self-switching design eliminates remote plumbing, saving panel space and wiring across decentralized stations.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAIF80X450S-08A Is Used
Decentralized Assembly Stations
Ideal for large machines where running individual valve lines is costly, using the integrated 4M310 valve to actuate clamps directly at the point of operation.
Space-Constrained Automation
Fits tight machinery footprints by combining the cylinder and valve into one assembly, eliminating bulky external valve islands and complex tubing.
Retrofit and Upgrades
Perfect for upgrading existing ISO 15552 lines where adding a remote pneumatic valve would require extensive new plumbing and electrical rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-08A the Right Choice?
Select this self-valved unit when decentralized stations require high thrust without the tubing runs of a separate remote valve. If you need less force, the 63mm bore neighbour offers 1559 N push at 0.5 MPa; stepping up to the 100mm bore yields 3927 N. The AC220V terminal coil suits standard plant voltages, while the PT1/4 valve port and 3/8 cylinder port provide distinct flow paths. For exact replacements, match the 80mm bore, 450mm stroke, 4M310-08 valve, AC220V terminal coil, PT threads, and -S magnet.
Because the 450mm stroke exceeds 300mm, ensure adequate guide support to prevent rod side-loading and premature seal wear. Note that the built-in 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, consider the SAIL lock or BSAI clamp-lock series instead.
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 SAIF80X450S-08A FAQ
At 0.5 MPa, the 80mm bore provides 2513 N push and 2268 N pull force. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
No, the SAIF80X450S-08A switches itself from one AC220V coil signal. The factory setting retracts the rod when energised, but you can reposition the integrated 5/2 valve to extend-when-energised.
