The AirTAC Airtac 4V Solenoid Valves 4V41015C-W is a genuine 5/2-way single solenoid (spring return) solenoid valve with W 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 4V41015C-W is the AC110V version of AirTAC's largest 4V body: a 5/2-way, single-solenoid spool valve with 1/2in PT tapered ports. Energise the coil and air routes to one side of a double-acting cylinder while the other side exhausts; cut the signal and the internal spring snaps the spool back, reversing the stroke. That makes it the natural choice for two-position strokes where the de-energised end position must be reached without logic. With an effective area of 48.0 mm2 (Cv 2.82) it moves enough air to cycle Dia 80-125 mm double-acting cylinders at up to 3 cycles per second. This exact SKU is supplied with a 4.5 VA AC110V coil wired to a screw-terminal box and a PT (Rc) port thread, so it drops straight into North American and Asian pipework that uses tapered seats. The aluminium body weighs 590 g, switches in 0.05 s or less, and carries IP65 (DIN40050) sealing with a B-class insulation coil. A locking or non-locking manual override lets maintenance staff stroke the valve by hand with the power off.

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 Dia 125 mm lift cylinder raising a dock leveler platform needs real airflow: Cv 2.82 fills the bore fast enough for a 3 c/s duty cycle, and the spring-return 5/2 function drops the leg to a defined position the moment the AC110V signal is removed.
Palletizer pushers stroke thousands of times per shift. The 0.05 s response and 48.0 mm2 effective area keep Dia 80-100 mm push cylinders sharp at the end of a conveyor line, while the spring return guarantees the ram clears the lane between layers.
Clamping packs of bricks or blocks uses a Dia 100-125 mm double-acting clamp cylinder. Clamps that must open on power loss suit the 10 function exactly: kill the AC110V signal and the spring exhausts the clamp side automatically.
Size in both directions. If your cylinder sits below roughly Dia 80 mm, the 4V300 body (Cv 1.65) is the cheaper, equally fast step down. If Cv 2.82 is still too small for your stroke speed, the 4V400 is already the largest 4V body, so the route up is a bigger valve series or a parallel manifold group rather than a larger 4V code. Choose this 10-function only if you want a guaranteed spring-return end position; if you prefer the valve to stay put after a pulse, look at the double-solenoid 4V420 instead. Replacing an existing unit? Match all five points: body size (4V400), function digit (10 = single solenoid spring return), port and thread (1/2in, PT here - G and NPT variants exist), coil voltage (AC110V for this code), and electrical entry (screw terminal box - grommet versions carry an I suffix).
Quick checklist
It is a 5/2 spring-return valve with an effective area of 48.0 mm2 (Cv 2.82) and a maximum frequency of 3 cycles per second. Activating time is 0.05 s or less. Operating pressure is 0.15-0.8 MPa with a 1.2 MPa proof pressure, media temperature -20 to +70 C, and the air must be filtered by a 40 um element. The AC110V coil draws 4.5 VA, insulation class B, protection IP65 (DIN40050), and the aluminium body weighs 590 g. It suits roughly Dia 80-125 mm double-acting cylinders.
Yes - it is the defining trait of the single-solenoid 10 function. The spool is held in the working position only while the AC110V coil stays energised; a spring pushes it back the instant the signal drops, reversing the cylinder. You therefore need a constant output for the extended position, not a pulse. De-energised, the valve is not a positive lock: if the application must hold a load against gravity, add a pilot-operated check valve at the cylinder port or a mechanical brake rather than relying on the valve alone.
