Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 50mm 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 SAIF80X50-10B
The AirTAC SAIF80X50-10B 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 Cv 1.68 via a 1/4" port, operating at 4 cycles per second. The unit is driven by a DC24V terminal coil drawing 3.0W, protected to IP65 with a 0.05s activation time. Because the cylinder rates to 1.0 MPa but the valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa.
This configuration delivers substantial thrust, generating 2513N of push force at 0.5 MPa. The manifold connects the valve to the cylinder using PU tubing (O10 x O6.5), keeping the valve port distinct from the cylinder's PT3/8 port. Factory set to retract the rod when the coil is energized, the valve can be repositioned to extend-when-energized. This self-switching design eliminates remote plumbing, making it perfect 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)

|---|---|---|
| 0.5 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 SAIF80X50-10B Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, eliminating long tubing runs by switching directly from the DC24V coil signal.
High-Force Clamping
Provides 2513N of push force at 0.5 MPa for heavy-duty clamping and holding tasks without needing a separate remote valve bank.
Space-Constrained Retrofits
Perfect for machinery upgrades where adding a new valve manifold is impossible, using the built-in 4M310 valve to save panel space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X50-10B the Right Choice?
Choose this 80mm bore when you need high force (2513N push at 0.5 MPa) that exceeds the 1559N push of a 63mm bore, but do not require the 3927N output of a 100mm bore. A self-valved SAIF excels over a separate cylinder and remote valve when panel space is tight and running tubing is costly. This specific SKU specifies a DC24V terminal coil, a PT3/8 cylinder port, and a 4M310-10 valve with a 3/8" port. For exact replacements, match the 80mm bore, 50mm stroke, 3/8" valve port, DC24V voltage, terminal entry, PT thread, and no magnet. Note that the 5/2 valve routes air and does not lock the load; for position holding, consider the SAIL lock or BSAI clamp-lock series.
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 SAIF80X50-10B FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5 MPa. The integrated 4M310-10 5/2 valve provides a 30.0 mm2 orifice with a Cv of 1.68.
It uses a 4M310 5/2 solenoid valve, so no separate remote valve is needed. This model features a DC24V terminal coil. By factory default, the piston retracts when the coil is energized, but this can be reconfigured to extend-when-energized by repositioning the valve.
