The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X150S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 150mm 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.
The AirTAC SAIF80X150S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides a Cv of 1.40 and operates via a PT1/4 port, while the cylinder itself uses a PT3/8 port. Driven by an AC220V terminal coil drawing 3.5 VA, it switches in 0.05s with an IP65 rating. The standard carbon steel rod and included -S magnet enable precise position sensing with CMSE reed and DMSE electronic switches.
Because the cylinder body rates to 1.0 MPa but the integrated 4M valve limits the operating pressure, the practical working range for this assembled unit is 0.15-0.8 MPa. Generating 2513 N of push force at just 0.5 MPa, it switches itself from one coil signal without needing a remote valve. This decentralized architecture minimizes plumbing and panel space. Factory-set to retract the piston rod when the coil is energized, the valve can be repositioned to extend-when-energized if your sequence demands it.

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.

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).
Eliminates the need for a central valve bank by switching directly from the AC220V coil signal, reducing tubing runs across large factory layouts.
Provides 2513 N of push force at 0.5 MPa for holding heavy workpieces, while the integrated valve ensures rapid 0.05s response times.
The built-in 4M310-08 valve saves valuable panel space and simplifies machine design in compact pneumatic setups.
Select this 80mm bore when a 63mm bore yielding 1559 N at 0.5 MPa is insufficient, or step down from a 100mm bore (3927 N at 0.5 MPa) if you need to save envelope space. The self-valved SAIF80X150S-08A excels over a separate cylinder and remote valve by eliminating long tubing runs, cutting wiring complexity, and enabling decentralized machine stations. It includes an -S magnet for CMSE/DMSE sensors and uses a PT1/4 valve port with PT3/8 cylinder ports.
When ordering a replacement, verify the 150mm stroke, 80mm bore, 4M310-08 valve, AC220V terminal coil, PT thread type, and the -S magnet. Note that the 5/2 valve routes air but does not lock the load mechanically; for position holding without live pressure, consider an AirTAC SAIL lock cylinder. As stroke length increases, always ensure adequate guide support to prevent rod side-loading.
Quick checklist
At 0.5 MPa, this 80mm bore double-acting cylinder generates 2513 N of push force and 2268 N of pull force. The integrated 4M310-08 valve has a flow capacity of Cv 1.40.
No, the integrated 4M310 5/2 valve is internally piloted and driven directly by the AC220V terminal coil. By default, it retracts the rod when energized, but you can reposition the valve to extend-when-energized.
