Airtac SAIF Series Standard Cylinder with Valve SAIF80X700-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X700-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 700mm 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 SAIF80X700-08A
The AirTAC SAIF80X700-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve delivers a Cv of 1.40 and a 25.0 mm2 effective area, driving the 80mm bore to achieve 4523N of push force at 0.9 MPa. Equipped with an AC220V terminal coil consuming 3.5 VA, it activates in 0.05s. The assembly operates within a practical 0.15-0.8 MPa range, as the valve limits the cylinder's 1.0 MPa base rating.
By switching itself directly from one coil signal, this unit eliminates remote plumbing and saves panel space, making it ideal for decentralized machine stations. The factory default setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if needed. The manifold connects via O10 x O6.5 PU tubing, and the valve's 1/4" PT port is distinct from the cylinder's 3/8" PT port. Note that the 5/2 valve and air cushions only control motion; they do not lock the load.

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 SAIF80X700-08A Is Used
Decentralized Assembly Lines
Eliminates the need for long air lines back to a central manifold, providing localized 80mm bore actuation directly at the workstation.
Large Press Handling
Delivers 4523N of push force at 0.9 MPa for clamping or positioning heavy workpieces over a 700mm travel distance.
Retrofit Automation
Ideal for upgrading older machines where routing new pneumatic tubing to a remote valve is costly or physically constrained.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X700-08A the Right Choice?
Choose this self-valved SAIF80X700 configuration when your application requires substantial thrust (4523N push at 0.9 MPa) across a 700mm stroke without the tubing overhead of a remote valve bank. If you need less force, stepping down to a 63mm bore yields 2805N push at 0.9 MPa, whereas a 100mm bore offers 7068N for heavier loads. The integrated 4M310 valve supports a maximum frequency of 4 cycles per second. Ensure your replacement matches the 80mm bore, 700mm stroke, 08 valve port, AC220V terminal coil, PT thread, and standard carbon steel rod. Because the stroke is 700mm, always use 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 SAIF80X700-08A FAQ
The 80mm bore generates 4523N of push force and 2268N of pull force at 0.9 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 with a Cv of 1.40.
It uses an AC220V terminal coil (3.5 VA) to drive the 5/2 valve with a 0.05s response time. By default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. No separate remote valve is needed.
