Airtac SAIF Series Standard Cylinder with Valve SAIF32X225-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X225-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 225mm stroke and a built-in 4M210-08 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 SAIF32X225-08B
The AirTAC SAIF32X225-08B is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by a DC24V terminal coil drawing 3.0 W, it activates in 0.05 s or less. While the bare cylinder rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the true working pressure range for this assembled unit. It delivers 402N of push force at 0.5 MPa.
By integrating the valve directly on a manifold block via an O8xO5 PU tube, this unit switches itself from one coil signal, eliminating remote plumbing and saving panel space. 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. The cylinder port is PT1/4, while the valve port code is 08.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAIF32X225-08B Is Used
Decentralized Assembly Stations
Perfect for large machines with multiple small actuation points, eliminating long valve tubing runs by switching directly from the DC24V coil signal.
Compact Clamping Fixtures
Provides 402N of push force at 0.5 MPa in tight spaces where mounting a separate 5/2 valve and manifold block is physically impractical.
Space-Constrained Automation
The integrated profile cylinder and valve assembly minimize overall envelope while maintaining ISO 15552 mounting interchangeability.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X225-08B the Right Choice?
Choose this 32mm bore when 402N of push force at 0.5 MPa is sufficient; if your application requires greater thrust, stepping up to the 40mm bore yields 628N push at the same pressure. A self-valved SAIF32X225-08B is superior to a separate cylinder and remote valve when you need decentralized stations across a large machine, as it drastically reduces tubing runs and wiring complexity. For replacements, verify the 32mm bore, 225mm stroke, 1/4" valve port, DC24V voltage, terminal electrical entry, and PT thread. Note that this 225mm stroke exceeds 300mm, so ensure adequate guide support to prevent excessive side loading on the 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 SAIF32X225-08B FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The built-in 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
No, it switches itself using the integrated 4M210-08 5/2 valve and a DC24V terminal coil. By default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
