Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 300mm 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 SAIF80X300S-10A
The AirTAC SAIF80X300S-10S is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-10 5/2 solenoid valve. This integrated valve delivers a 30.0 mm2 effective area (Cv 1.68) and handles up to 4 cycles per second. Driven by an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05 s or less. Because the manifold uses O10 x O6.5 PU tubing to bridge the cylinder and valve, the 3/8 inch valve port differs from the cylinder's own 3/8 inch port. The carbon steel piston rod provides robust actuation, and the -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.
While the bare cylinder is rated for 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. It delivers 2513 N of push force at 0.5 MPa and 3518 N at 0.7 MPa. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. This self-switching design eliminates remote valves, saving panel space and simplifying decentralized machine stations.

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 SAIF80X300S-10A Is Used
Decentralized Automation
Ideal for large factory layouts where running air tubing to a central valve bank is inefficient. The built-in 4M310 valve lets this 80 mm bore cylinder operate independently from a single AC220V signal.
Material Handling Diverters
Provides 2513 N of push force at 0.5 MPa for actuating heavy diverter gates on conveyors. The 300 mm stroke offers the extended reach needed for wider product lines.
Compact Machining Cells
Saves valuable panel space in tight machining cells. The integrated valve and terminal entry eliminate the need for external solenoid mounts, keeping the envelope lean.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-10A the Right Choice?
Select this 80 mm bore when you need substantial thrust (up to 513 kgf at 1.0 MPa) without the plumbing of a remote valve island. If your application requires less force, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa; stepping up to 100 mm provides 3927 N. The 300 mm stroke is well within the 1500 mm maximum standard, but at this length you should incorporate a guide to prevent side-load wear on the rod seals. Remember the 5/2 valve routes air and is not a lock; if you need fail-safe load holding, consider the SAIL series instead.
To replace this unit, match the 80 mm bore, 300 mm stroke, PT3/8 valve port, AC220V terminal coil, and -S magnet. The PT tapered threads ensure tight pneumatic seals. This decentralized configuration is ideal for large machines where running individual valve tubing back to a central manifold is costly and complex.
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 SAIF80X300S-10A FAQ
At 0.5 MPa, the 80 mm bore generates 2513 N of push force and 2268 N of pull force. The built-in 4M310-10 valve provides an effective area of 30.0 mm2 (Cv 1.68), ensuring high flow rates for rapid actuation up to 4 cycles per second.
It uses a 5/2 solenoid valve that holds position via internal pilot pressure, not a spring. By factory default, energizing the AC220V coil retracts the rod, but you can reposition the valve to extend-when-energised. This eliminates the need for a separate remote valve.
