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 AirTAC 4V41015C-W is the AC110V, terminal-box version of the largest 4V body, built as a single-solenoid 5/2 valve with spring return: energise the coil to send air to one side of a double-acting cylinder, cut the signal and the spring snaps the spool back to the exhaust position. This -W variant uses an EXTERNAL pilot feed, so the pilot air arrives through a dedicated port rather than being tapped off the main supply - a real advantage on low-pressure mains or vacuum-side circuits where an internally piloted valve would fail to shift reliably.
With an effective area of 48 mm² (Cv 2.82) it sits at the top of the 4V family, well matched to bores in the ~80-125 mm range. The AC110V coil draws just 4.5 VA, switching completes in 0.05 s or less, and the valve weighs 590 g. It ships with a PT (Rc tapered) 1/2" port thread, a terminal box for fixed conduit wiring, IP65 sealing and a manual override, and it mounts on a base for integrated manifold group building.

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 80-125 mm double-acting clamp and press cylinders at Cv 2.82, with the spring return guaranteeing retraction whenever the AC110V signal is dropped.
The external pilot port lets this valve shift dependably on circuits where main-line pressure is too low to pilot an internally fed valve, such as vacuum conveyor lifters.
Cycles big gate, pusher and stopper cylinders on packaging and palletising lines, with a 0.05 s response and 3 cycles/sec capability keeping pace with the line.
Pick the 4V41015C-W when your line pressure may drop or run under vacuum and you still need positive spool shifting - the external pilot port keeps the valve operational where internal piloting cannot. If your cylinder is 50-63 mm or smaller, step down to the 4V300 (Cv 1.65) for better cost and speed; the 4V400 is the biggest 4V body, so for flow beyond Cv 2.82 you move to a larger valve series or parallel manifold arrangement.
Choose single solenoid (this model) when a constant electrical signal should track cylinder position and the cylinder must return on signal loss; pick a double-solenoid 4V420 when you need position memory instead. For an exact replacement, match five points: body size 4V400, function 10, 1/2" port with PT thread, AC110V coil, and terminal electrical entry - plus the -W external-pilot option.
Quick checklist
It converts the valve to external-pilot operation. Instead of bleeding pilot air from the main supply internally, pilot air is piped to a separate port. That keeps switching positive when supply pressure is low or the valve sits in a vacuum or low-pressure circuit. All other data - 48 mm² effective area, Cv 2.82, AC110V 4.5 VA coil, 590 g weight - is unchanged.
No. As a single-solenoid spring-return 5/2 valve, de-energising it actively exhausts one cylinder side and drives the piston to its rest position - useful for fail-safe retraction, not for holding mid-stroke. If you need a load parked indefinitely, select a 5/3 closed-center model or add pilot-operated check valves at the cylinder ports.
