Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 450mm stroke and a built-in 4M310-10 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-10A
The AirTAC SAIF80X450S-10A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve provides an effective flow rate of 30.0 mm2 (Cv 1.68) and operates at 4 cycles per second. Supplied with an AC220V terminal coil drawing 3.5 VA, it includes a magnet for position sensing with CMSE reed and DMSE electronic switches. The standard carbon steel piston rod has an M20x1.5 thread.
Because the 5/2 valve operates from 0.15 to 0.8 MPa, the practical working pressure range of this assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it generates 2513 N of push force. By default, the piston rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised. The manifold uses O10 x O6.5 PU tubing, and the valve port (3/8) differs from the cylinder port (3/8). This self-contained design eliminates remote plumbing, saving panel space for decentralized machine 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)

| 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-10A Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines by driving the 4523 N stroke directly from a single AC220V signal.
Space-Constrained Automation
The integrated 4M310-10 valve and manifold block drastically reduce external tubing and panel footprint in tight cell layouts.
Retrofitting Existing Lines
Ideal for upgrading older lines where routing new valve plumbing back to a central control cabinet is impractical or too expensive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X450S-10A the Right Choice?
Choose this 80mm bore if your application requires high thrust, such as the 2513 N push force at 0.5 MPa or 4523 N at 0.9 MPa. If your force requirements are lower, stepping down to a 63mm bore yields 1559 N push at 0.5 MPa, while moving up is not possible as 80mm is near the top of the SAIF range. The self-valved SAIF architecture is ideal when running separate valve tubing to a centralized panel is costly or space-prohibitive. This specific SKU uses an AC220V terminal connection with PT threaded ports. Note that the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, consider the SAIL lock cylinder. For stroke lengths of 450mm or more, ensure your machine design includes a guide to prevent excessive side loading on the piston rod.
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-10A FAQ
The 80mm bore generates 2513 N of push force at 0.5 MPa and 4523 N at 0.9 MPa. The built-in 4M310-10 5/2 valve has a 30.0 mm2 orifice, providing a Cv of 1.68.
No separate remote valve is needed because the 4M310 valve is built directly onto the cylinder. By factory default, the rod retracts when the AC220V coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
