About the AirTAC 4V410-15 Solenoid Valve, 4V400 Series (4V41015A-W)
The 4V41015A-W is the external-pilot version of AirTAC's largest 4V body: a 5/2-way, single-solenoid spool valve with 1/2" PT ports, an AC220V coil drawing 4.5 VA, and wiring through a screw-terminal box. The -W option feeds the pilot stage from a dedicated external pilot port rather than tapping the main line internally, so the spool keeps shifting cleanly even where main-line pressure runs low or the circuit sits at vacuum or near-zero pressure. Being single solenoid, it needs a constant electrical signal to stay shifted; de-energise the coil and the return spring drives the spool back, sending air to the opposite side of the actuator.
In flow terms this is the top of the 4V range: 48 mm2 effective area (Cv 2.82) through the 5/2 path, with response at 0.05 s or better and a 3 cycle/sec ceiling. That capacity suits double-acting cylinders of roughly 80-125 mm bore, and at 590 g it is the heaviest single-coil valve in the family. The aluminium body runs 0.15-0.8 MPa, tolerates 1.2 MPa proof, and is IP65 protected against dust and washdown jets.

Flow & Coil Options
| Effective area | 48.0 mm² |
|---|---|
| Flow coefficient | Cv 2.82 |
| Response time | ≤ 0.05 s |

Where the AirTAC 4V410-15 Solenoid Valve, 4V400 Series (4V41015A-W) Is Used
Heavy clamping fixtures
The 48 mm2 orifice fills large clamp and swing-cylinder volumes quickly, while the external pilot keeps switching positive on clamping circuits that run at reduced main pressure.
Vacuum and low-pressure circuits
Because the pilot feed is external, this valve stays fully actuated where an internally piloted valve would stall - ideal for vacuum hold-down tables and near-atmospheric transfer lines.
Press and lift actuators
Spring return gives a defined retraction on power loss for 80-125 mm double-acting press, lift and dump cylinders, with 0.05 s response keeping the cycle sharp.
Is the AirTAC 4V410-15 Solenoid Valve, 4V400 Series (4V41015A-W) the Right Valve?
Choose this SKU when your main supply cannot be trusted to pilot the valve internally - vacuum conveyors, low-pressure holding circuits, or lines that sag during start-up all benefit from the -W external pilot arrangement; simply plumb a stable pilot feed to the external port. If your cylinder is below about 63 mm, the 4V300 (Cv 1.65) is the more economical step-down, and note that no 4V4 body exceeds this Cv - for larger flows move to a bigger series or build a manifold group on a common base. Between functions: pick this single-solenoid 10 type for fail-safe spring return, a 4V420 double-solenoid for a remembered position, or a 4V430C/E/P 5/3 for mid-stroke control (bearing in mind 5/3 flow drops to Cv 2.35).
For replacement matching, confirm all five points: body size 4V400, function 10 (single solenoid, spring return), 1/2" PT thread (Rc taper - switch to -15AG for BSPP or -15AT for NPT), coil voltage AC220V, and terminal-box entry rather than the grommet lead.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center

- ✓ Port thread (M5 / 1/8 / 1/4 / 3/8 / 1/2)
- ✓ Single valve or manifold base?
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.8 MPa operating pressure.
- check Match coil voltage to your controller output.
- check Use the manual override to test before powering.
- check Fit silencers or fittings to the exhaust ports.
- check Wiring by qualified personnel per AirTAC docs.
AirTAC 4V410-15 Solenoid Valve, 4V400 Series (4V41015A-W) FAQ
It directs compressed air to double-acting cylinders and actuators with 48 mm2 effective area (Cv 2.82), so it comfortably serves bores in the 80-125 mm range. The -W suffix means external pilot: pilot air comes from a separate port instead of the main line, which keeps the spool switching dependably in low-pressure or vacuum service where an internally piloted valve may not shift.
This is a single-solenoid, spring-return valve: the coil must stay energised to hold the extended position, and removing the 220 V AC signal lets the spring snap the spool back and reverse the cylinder. The AC220V / 4.5 VA coil is wired at the built-in screw-terminal box, and a manual override on the end cap lets you cycle the valve by hand during set-up or fault-finding.
