Airtac SAIF Series Standard Cylinder with Valve SAIF32X250-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250-06A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm stroke and a built-in 4M210-06 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 SAIF32X250-06A
The AirTAC SAIF32X250-06A is a double-acting ISO 15552 profile cylinder that integrates a 4M210-06 5/2 solenoid valve directly onto its manifold block. This specific SKU features a 1/8" valve port (PT thread) and an AC220V terminal coil connection, drawing 3.5 VA with IP65 protection. The built-in valve provides an effective area of 14.0 mm2 (Cv 0.78) and handles up to 5 cycles per second. Because the cylinder body rates to 1.0 MPa but the 4M valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. In this 32mm bore class, it generates 402N of push force at 0.5 MPa.
By mounting the valve on the cylinder, this unit switches itself from a single coil signal, eliminating remote plumbing and saving panel space for decentralized machine stations. The manifold bridges the valve to the cylinder using an O8 x O5 PU tube, meaning the 1/8" valve port differs from the cylinder's own port. Factory set to retract the piston rod when the coil is energised, the valve can be physically repositioned to extend-when-energised if your sequence requires it. This configuration uses a standard carbon steel rod and does not include a magnet for sensors.

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 SAIF32X250-06A Is Used
Decentralized Machine Stations
Ideal for distributing actuators across large equipment, using a single AC220V signal to drive the cylinder locally without a remote valve bank.
Compact Assembly Lines
Saves panel space by mounting the 4M210 valve directly on the profile cylinder, keeping the 32mm bore's 402N thrust in a tight envelope.
Retrofit Automation
Perfect for upgrading existing systems where routing new pneumatic tubing is costly, as the unit switches itself via the integrated valve.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250-06A the Right Choice?
Choose this self-valved SAIF32X250-06A when you need to decentralize actuation across a large machine and want to avoid running long valve tubing back to a central manifold. The 32mm bore delivers 402N push at 0.5 MPa; if your payload needs less force, there is no smaller bore in the SAIF range, but if you need more thrust, stepping up to the 40mm bore yields 628N push at 0.5 MPa. For this 250mm stroke, ensure you provide adequate guide rails to prevent side-load damage to the rod seals. Remember that the 5/2 valve routes air but does not lock the load mechanically—use AirTAC SAIL or BSAI cylinders if position holding without live pressure is required. To replace this unit exactly, match the 32mm bore, 250mm stroke, 06 (1/8") valve port, AC220V terminal coil, PT thread, and no magnet (-S).
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 SAIF32X250-06A FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
The integrated 5/2 valve drives the cylinder from a single AC220V coil signal. Factory set to retract-when-energised, it can be repositioned to extend-when-energised. It routes air but does not lock the load without live pressure.
