Airtac SAIF Series Standard Cylinder with Valve SAIF80X900S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X900S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 900mm 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 SAIF80X900S-08A
The AirTAC SAIF80X900S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a 2513N push force at 0.5 MPa. Because the cylinder body rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The valve achieves a 25.0mm2 effective area (Cv 1.40) and switches up to 4 cycles per second.
This model includes a magnet for CMSE and DMSE sensors, allowing precise end-of-stroke detection where electronic solid-state or reed switches are required. By default, the piston rod retracts when the coil is energised, though you can reposition the valve to extend-when-energised. The manifold connects to the cylinder via O10xO6.5 PU tubing, meaning the 1/4" valve port and 3/8" cylinder port are distinct. This decentralized design eliminates remote valves, saving panel space and plumbing across large machines.

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)

| 0.5 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 SAIF80X900S-08A Is Used
Decentralized Conveyor Diverters
Eliminates the need for a remote valve bank on long conveyor lines, driving the 900mm stroke directly from a local AC220V signal.
Large Machine Handling
Provides 2513N push force at 0.5 MPa for heavy product handling, using the built-in 4M310 valve to save panel space.
Retrofit Automation Stations
Ideal for upgrading older machines where routing new pneumatic tubing to a central manifold is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X900S-08A the Right Choice?
Choose this 80mm bore when you need substantial thrust (2513N push at 0.5 MPa) but want to step down from the 100mm bore (3927N) to save envelope space, or upgrade from the 63mm bore (1559N) for heavier loads. The self-valved SAIF architecture is ideal for space-tight machines or retrofits where running tubing to a remote valve bank is costly. A single AC220V terminal connection drives the entire actuator. For position feedback, pair the -S magnet with AirTAC DMSE electronic or CMSE reed switches.
Because the stroke is 900mm, ensure adequate guide support to prevent excessive side loading on the rod and seals. Remember that the 5/2 valve routes air but does not lock the load; if mechanical holding is required, consider an AirTAC SAIL lock cylinder. When ordering a replacement, match the 80mm bore, 900mm stroke, 4M310-08 valve, AC220V voltage, terminal entry, PT thread, and -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 SAIF80X900S-08A FAQ
At 0.5 MPa, the 80mm bore provides a push force of 2513N and a pull force of 2268N. The integrated 4M310-08 5/2 valve has an effective area of 25.0mm2 (Cv 1.40).
The factory default setting retracts the rod when the AC220V coil is energised. This can be reconfigured to extend-when-energised by repositioning the valve on the manifold.
