The AirTAC Airtac 4V Solenoid Valves 4V11006EIT is a genuine 5/2-way single solenoid (spring return) solenoid valve with 11006EIT ports and an effective area of 10.2 mm² (Cv 0.6). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The 4V110-06EIT is the AC24V grommet-wired version of the AirTAC 4V100 single-solenoid valve. It sends compressed air to one side of a double-acting cylinder while exhausting the other, and when the coil is de-energised an internal spring snaps the spool back, so the actuator always returns to its rest position. With a 10.2 mm2 effective area (Cv 0.6) it is sized for small bores in the Dia16-32 mm range, cycling up to 5 times per second. This exact SKU is built for US-style NPT 1/8 piping and a 24 V AC control circuit drawing 4.0 VA - the voltage most often found on machines fed from a panel control transformer. Instead of a terminal box, the coil exits through a grommet with a 0.5 m pre-wired flying lead, which speeds up cabinet assembly and removes loose terminal work. The valve meets IP65 (DIN40050), responds in 0.05 s or less, weighs just 120 g, and runs on filtered air (40 um element) without lubrication.

Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

A small parallel gripper on an electronics assembly stand opens and closes hundreds of times per hour; the 4V110-06EIT Cv 0.6 orifice keeps the cycle crisp while the spring return guarantees the gripper opens at every power-off, protecting the PCB in transit.
Swing clamps and edge clamps on a carton sealing fixture retract when the 24 V AC control loop drops; this valve's spring return gives that fail-to-rest behaviour, and its 1/8 NPT ports pipe straight into North American clamp plumbing.
A Dia16-25 mm pusher cylinder ejects sample trays from a materials test station; with 4.0 VA coil draw on the lab's 24 V AC supply and a 0.5 m grommet lead, the valve drops straight into a crowded enclosure without extra terminal blocks.
Size both ways before ordering. Step down to the 4V110-M5 variant when your cylinder is tiny and fittings matter more than flow - the M5 ports keep the same Cv 0.6 but suit compact manifolds on benchtop fixtures. Step up to the 4V210-08 (Cv 1.0, 1/4 ports) if your cylinder grows past Dia32 mm or the cycle feels slow: a Dia20 bore develops about 16 kgf push at 0.5 MPa and a Dia32 bore about 41 kgf, both well within this valve, but speed drops as bore and stroke rise. Function-wise, choose this single-solenoid 5/2 only when you want a guaranteed spring-return rest state; pick a 4V120 double solenoid if the cylinder must remember its position after a power cut. For replacement work, match all five points of the code: 4V100 body, function 10, 1/8 NPT port (T thread), AC24V coil, and grommet entry (the I in the code). Any single-letter difference changes wiring or pipework. One valve mounts directly, or seat several on a common base to build an integrated manifold group with shared air supply.
Quick checklist
Flow capacity is an effective area of 10.2 mm2 (Cv 0.6) on the 5/2 spool, with a maximum switching frequency of 5 cycles per second and a response time of 0.05 s or less. Operating pressure spans 0.15-0.8 MPa with a 1.2 MPa proof pressure, and the valve works from -20 to +70 C on air filtered to 40 um. The AC24V coil draws 4.0 VA, insulation is class B, protection IP65, and the unit weighs 120 g.
The EIT suffix fixes three options at once: an AC24V coil for control circuits fed from a panel transformer, grommet entry with a 0.5 m flying lead instead of a terminal box, and NPT threads on the 1/8 ports. The pre-wired lead suits machines where the coil sits in a tight spot or where you want a plug-and-play swap without rewiring terminals. If your panel is DC or you pipe in PT or G, order the matching code letter instead - mixing voltage or thread codes is the most common replacement error.
