The AirTAC Airtac 4V Solenoid Valves 4V41015AG is a genuine 5/2-way single solenoid (spring return) solenoid valve with 41015AG ports and an effective area of 48.0 mm² (Cv 2.82). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The 4V410-15AG is the single-solenoid 5/2-way valve in AirTAC's largest 4V body, wired for AC220V mains through a 4.5VA coil and a lockable terminal-box entry. With 1/2-inch G (BSPP parallel) ports on every station, it sends compressed air to one side of a double-acting cylinder while venting the other, and its internal spring snaps the spool back the instant the coil is de-energised - so the solenoid signal must stay on for as long as you want the cylinder extended. Effective area is 48.0 mm2 (Cv 2.82), placing this valve at the top of the 4V range for flow.
At that Cv class the 4V410-15AG comfortably feeds bores in the ~O80-125 mm bracket, and the spool switches in 0.05 s or less, so even large pistons start moving with almost no signal lag. The aluminium body weighs 590 g, air is filtered by a 40 um element, lubrication is not required, and the valve is IP65 (DIN40050) rated. Base mounting lets several 4V400 valves join into one integrated manifold group.

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.

Drives O80-125 mm double-acting clamp and press cylinders where Cv 2.82 flow fills the full bore quickly and the spring return guarantees retraction whenever the 220 V signal drops.
Extends and retracts big pusher, lifter and gate cylinders on conveying and palletising lines, with the terminal box giving a tidy mains-voltage connection at the machine.
Suits production machinery whose primary double-acting stroke needs the largest 4V flow class, with BSPP G 1/2in ports matching standard parallel-thread pneumatic fittings.
Choose this AC220V / G-thread variant when your control panel supplies 220 V AC and your plumbing is BSPP parallel - no adapters or step-down transformer needed. If the target cylinder is below roughly O80 mm, the 4V300 body (Cv 1.65) will cycle it just as well at lower cost; step up to 4V400 only when the bore and speed demand the 48.0 mm2 / Cv 2.82 class. The 4V400 is the biggest 4V body, so for flow beyond Cv 2.82 move to a larger valve series or manifold. A double-solenoid 20 model remembers its last position on power loss, and the 30C/E/P 5/3 variants add a defined center condition - pick the 10 single-solenoid only when a de-energised return is the behaviour you want.
Ordering a replacement? Match all five points: body size (4V400), function (10 = single solenoid, spring return), port and thread (1/2", G), coil voltage (AC220V) and electrical entry (terminal box).
Quick checklist
It is a 5/2 valve with 48.0 mm2 effective area (Cv 2.82), sized for double-acting cylinders in the ~O80-125 mm range. Spool actuation takes 0.05 s or less, and the valve cycles up to 3 times per second.
That is the spring-return design working as intended. The 4V410-15AG holds its shifted position only while the AC220V coil stays energised; removing the signal lets the internal spring push the spool back and exhaust the cylinder's extend side. If you need the cylinder to stay put after a power cut, use a double-solenoid 4V420 or a 5/3 center valve instead.
