Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-08B 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-08B
The AirTAC SAIF80X450S-08B is a double-acting ISO 15552 profile cylinder paired with a built-in 4M310-08 5/2 solenoid valve. This specific configuration delivers a 25.0 mm2 orifice (Cv 1.40) and operates on a DC24V terminal connection drawing 3.0 W. The integrated manifold connects to the cylinder via O10 x O6.5 PU tubing, meaning the 1/4" valve port and 3/8" cylinder port serve distinct routing functions. The base cylinder is dimensionally interchangeable per ISO 15552, while the valve manifold adds localized control.
Although the cylinder body rates up to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for position feedback. At 0.5 MPa it generates 2513 N of push force and 2268 N of pull force.

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)

| 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-08B Is Used
Decentralized Automation Stations
Eliminates the need for a remote valve island on large machines by switching directly from a single DC24V signal, cutting tubing complexity.
High-Force Clamping Fixtures
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces, utilizing the built-in 4M310 valve for rapid 4 cycle/sec actuation.
Space-Constrained Machinery
Ideal for tight envelopes where running separate valve lines is costly, leveraging the integrated manifold and O10 x O6.5 PU tubing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-08B the Right Choice?
Choose this 80mm bore when an application requires higher thrust than the 63mm option (1559 N push at 0.5 MPa) but does not need the full 3927 N push of the 100mm variant. The self-valved SAIF design eliminates remote valve plumbing, saving panel space and reducing tubing runs across decentralized machine stations. A single DC24V terminal connection drives the entire actuator, responding in 0.05 s with IP65 protection.
For this 450mm stroke, adding an external guide is recommended to manage side loads and prevent rod binding. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider the SAIL lock series instead. Replacement matches require the 80mm bore, 450mm stroke, 1/4" valve port, DC24V terminal coil, 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 SAIF80X450S-08B FAQ
The 80mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles/sec.
No, the 5/2 valve routes air but does not lock the load; you need live pressure to hold position. The factory setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
