Airtac SAIF Series Standard Cylinder with Valve SAIF80X225S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X225S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 225mm 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 SAIF80X225S-08B
The AirTAC SAIF80X225S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. Featuring a 3/8 inch cylinder port and a 1/4 inch valve port, it delivers a Cv of 1.40. Driven by a DC24V terminal coil consuming 3.0 W, it achieves an IP65 rating and a rapid 0.05 s response time. The integrated manifold uses O10 x O6.5 PU tubing to bridge the valve and cylinder.
Although the cylinder body rates to 1.0 MPa, the built-in valve limits the practical working pressure to 0.15-0.8 MPa. Generating 2513 N of push force at 0.5 MPa, it includes a magnet for CMSE or DMSE sensors. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. This decentralized design eliminates remote valves, saving panel space and tubing 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)
| 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 SAIF80X225S-08B Is Used
Decentralized Automation
Eliminates remote valve banks by switching directly from a DC24V signal, minimizing tubing across sprawling factory layouts.
High-Force Assembly
Delivers 2513 N of push force at 0.5 MPa for pressing and joining tasks where space prohibits a separate valve.
Retrofit Machinery
Ideal for upgrading older machines where running new pneumatic tubing to a central panel is costly and complex.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X225S-08B the Right Choice?
Choose this 80 mm bore when a 63 mm cylinder (1402 N pull at 0.5 MPa) cannot provide the required thrust, but a 100 mm bore is excessive. The self-valved SAIF80X225S-08B excels over a separate cylinder and remote valve by consolidating wiring and plumbing into one decentralized station. To replace this unit, match the 80 mm bore, 225 mm stroke, 3/8 inch cylinder port, 4M310-08 valve, DC24V terminal coil, PT thread, and the -S magnet. Since the stroke is under 300 mm, standard mounting handles the load without extra side-load guides. Remember, the 5/2 valve routes air but does not lock the load; use a SAIL lock cylinder for position holding.
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 SAIF80X225S-08B FAQ
The 80 mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The built-in 4M310-08 valve provides a 25.0 mm2 orifice with a Cv of 1.40.
The DC24V terminal coil energizes the 5/2 valve to route air, defaulting to retract-when-energised but reconfigurable to extend. The valve routes air but does not lock the load; use a SAIL cylinder for holding.
