About the AirTAC 4V410-15 Solenoid Valve, 4V400 Series (4V41015B-W)
The AirTAC 4V41015B-W is a 4V400-series 5/2 single-solenoid directional valve built around the external-pilot (-W) option: pilot air is supplied through a separate external pilot port rather than tapped from the main bore, so the spool keeps shifting cleanly even when line pressure drops low or the circuit runs under vacuum or near-zero supply. De-energising the coil lets the spring snap the spool back, so the valve needs a maintained electrical signal to hold a cylinder in its working position. It directs compressed air to double-acting cylinders and actuators in the large-bore class, with an effective area of 48.0 mm2 (Cv 2.82) that suits bores of roughly 80-125 mm.
This exact SKU pairs a DC24V coil rated at 3.0 W with a terminal-box electrical entry and PT (Rc tapered) 1/2" ports - a low-voltage setup favoured on mobile equipment, battery-backed DC control panels and anywhere 24 V wiring is already routed to the valve station. Response is 0.05 s or better, protection is IP65, and the aluminium body weighs 590 g.

Flow & Coil Options
| Effective area | 48.0 mm² |
|---|---|
| Flow coefficient | Cv 2.82 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |

Where the AirTAC 4V410-15 Solenoid Valve, 4V400 Series (4V41015B-W) Is Used
Low-pressure and vacuum process lines
External pilot supply keeps the spool switching on vacuum pick-and-place mains and low-pressure circuits where an internally piloted valve would fail to shift.
Heavy material handling
Cv 2.82 flow pushes 80-125 mm bore cylinders on pallet lifters, tipper arms and gate actuators, with spring return parking the load-side motion on power cut.
Manifolded clamp and press stations
Mounts into a 4V400 base-manifold group; the DC24V terminal-box coil drops straight into 24 V PLC-controlled clamping and forming fixtures.
Is the AirTAC 4V410-15 Solenoid Valve, 4V400 Series (4V41015B-W) the Right Valve?
Size check before you order: a 48.0 mm2 (Cv 2.82) flow path is the biggest in the 4V family, so drop to the 4V300 (Cv 1.65) if your cylinder is below about 80 mm - an oversized valve wastes air and money. For flow beyond what this 4V400 body passes, move up to a larger valve series or build a manifold group on a shared base. Choose this single-solenoid version when the actuator must return to rest on signal loss; pick a double-solenoid 4V420 for pulse-hold memory, or a 4V430C/E/P 5/3 (40.0 mm2, Cv 2.35) when a defined centre condition matters. The -W suffix matters most on low-pressure or vacuum mains where an internal-pilot tap would starve.
Reordering or cross-referencing? Match all five points: 4V400 body size, function 10 (5/2 single, spring return), 1/2" port with PT thread, DC24V coil, terminal entry - plus the -W external-pilot construction, since an internally piloted 4V410-15B is not a drop-in equal on a low-pressure line.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center
- ✓ Coil voltage (DC24 / AC220 …)
- ✓ 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 (4V41015B-W) FAQ
It is a 5/2 single-solenoid valve for double-acting cylinders and actuators, sized by a 48.0 mm2 effective area (Cv 2.82) - comfortable for bores around 80-125 mm. The -W option feeds pilot air from an external port instead of the main line, so switching stays reliable when supply pressure is low or the circuit runs in vacuum. AirTAC does not publish a minimum pilot-pressure figure for this valve; air must still be filtered through a 40 um element.
No - this is a spring-return valve, not a holding valve. De-energising the 3.0 W DC24V coil vents one cylinder port and connects the other to exhaust, so the rod retracts to its rest position. If the machine needs the load locked mid-stroke, you want the 4V430C closed-centre 5/3 plus a pilot-operated check valve or mechanical brake; this valve alone is not a fall-protection device.
