The AirTAC Airtac 4V Solenoid Valves 4V11006C-W is a genuine 5/2-way single solenoid (spring return) solenoid valve with W 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 AirTAC 4V11006C-W is a 5/2-way single-solenoid valve in the compact 4V100 body, built to switch compressed air between the two ports of a double-acting cylinder or actuator. Energise the coil and the valve shifts; cut the signal and the internal spring drives the spool back to its rest position, so it always needs a continuous electrical signal to hold the advanced state. With an effective area of 10.2 mm2 (Cv 0.6) it sits in the small-body flow class that pairs well with cylinders in the ~O16-32 mm bore range.
This -W variant is the EXTERNAL-PILOT version: pilot air is supplied through a separate external pilot port rather than being tapped internally from the main line. That means the spool still shifts dependably when main-line pressure is low or on vacuum / low-pressure circuits where an internally piloted valve could fail to switch. The AC110V coil draws 3.5 VA on a standard terminal-box entry, response time is 0.05 s or better, and the bare valve weighs just 120 g.

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.

Spring return guarantees a small double-acting clamp retracts whenever the AC110V signal drops, and the external pilot keeps it switching even on a low-pressure clamping circuit.
At Cv 0.6 with sub-0.05 s response, the valve gives crisp open/close control of compact grippers on pick-and-place heads where space and weight matter.
The -W external pilot port lets the spool shift reliably in vacuum-assisted or reduced-pressure lines that would leave an internally piloted 4V110 stranded mid-stroke.
Choose this single-solenoid 5/2 model when the actuator should always return to a known rest position on signal loss. If you need the cylinder to hold its last position through a power cut, step up to the double-solenoid 4V120 instead. For bores above ~32 mm or faster cycling, the 4V200 (Cv 1.0) is the next body size up, and any 4V100 valve can also be banked into an integrated manifold on a common base to save piping and wiring.
Ordering a replacement or a spare? Match all five points: body size (4V100), function (single solenoid 5/2, spring return), port and thread (1/8in PT), coil voltage (AC110V), electrical entry (terminal box) - and this unit's -W external-pilot option, which must match if your circuit feeds pilot air separately.
Quick checklist
It is a 5/2-way valve for double-acting cylinders and actuators, pressurising one side while exhausting the other. Its effective area is 10.2 mm2 (Cv 0.6), so it is sized for cylinders around O16-32 mm bore and allows cycling up to 5 cycles per second. Single-acting cylinders need a 3/2 valve, not this one.
-W means pilot air is fed to the valve from a separate external pilot port instead of being taken from the main supply inside the valve. Use it when main-line pressure may be too low to shift an internally piloted spool, or in vacuum and low-pressure circuits. Everything else - 5/2 spring-return function, 1/8in PT port, AC110V 3.5 VA terminal coil - is standard 4V110-06C.
