About the AirTAC 4V420-15 Solenoid Valve, 4V400 Series (4V42015-X0)
The AirTAC 4V42015-X0 is the bare valve body of the 4V420-15 - a 5/2-way double-solenoid spool valve shipped WITHOUT the coil and electrical connector, intended as a replacement or OEM build-in body. Pneumatically it is identical to the complete valve: it directs compressed air to double-acting cylinders and actuators, and because both solenoids are pulsed rather than continuously fed, the spool simply stays where it was last positioned, held by land friction and balanced pressure with no spring to pull it back and no holding current. It is not magnetically latched - the memory is purely mechanical.
This body sits at the top of the 4V range with an effective area of 48 mm2 (Cv 2.82), so it comfortably serves double-acting cylinders in the ~O80-125 mm bore class. The switching response is 0.05 s or below, the all-up weight is 720 g, and the spool runs at up to 3 cycles per second. Order the coil and connector separately at whatever voltage your panel uses.

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 |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |
| Manual override | Yes (locking / non-locking) |
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.

Where the AirTAC 4V420-15 Solenoid Valve, 4V400 Series (4V42015-X0) Is Used
Heavy clamping and press fixtures
The Cv 2.82 flow path fills large clamp and press cylinders fast, while the memory hold keeps the last pulsed state through a control-power drop - with a pilot-operated check or mechanical brake added wherever guaranteed load holding matters.
Large material-handling actuators
Suited to ~O80-125 mm bore cylinders on lifts, tipplers and heavy gate actuators, where the 48 mm2 effective area and 0.05 s response keep stroke reversal crisp at up to 3 cycles per second.
Spares stocking for 4V420 installations
A coil-less replacement body lets maintenance teams hold one 4V400 spare and reuse the coils already fitted in the panel, cutting downtime cost on multi-valve machines.
Is the AirTAC 4V420-15 Solenoid Valve, 4V400 Series (4V42015-X0) the Right Valve?
Choose this 4V400 body when a smaller 4V300 valve (Cv 1.65) no longer keeps up with cylinder speed or air demand; 4V400 is the largest 4V body, so for flows beyond Cv 2.82 step up to a larger valve series or build a manifold base. If you need spring-return single-solenoid behavior or a 5/3 center option (closed, exhaust or pressure), pick the matching 4V410 or 4V430 body instead of this memory-type 5/2.
When replacing an installed valve, match five points: body size (4V400), function (double solenoid, 5/2 memory), port and thread (1/2in PT tapered), the coil voltage you will order separately, and the electrical connector/entry style of your wiring. Since the -X0 suffix omits the coil, confirm the voltage code of your existing coil before ordering the body alone.
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 4V420-15 Solenoid Valve, 4V400 Series (4V42015-X0) FAQ
No. The -X0 suffix means bare valve body: it ships without the solenoid coil and without the electrical connector, so no voltage or wiring entry is included as supplied. Order the coil and connector separately at the voltage your control panel uses, or transfer the coil from the valve you are replacing. Every pneumatic characteristic - 5/2 double-solenoid memory function, 1/2in PT ports, 48 mm2 effective area, Cv 2.82 - is unchanged from the complete 4V420-15.
With Cv 2.82 (48 mm2) it drives double-acting cylinders and actuators, sized around O80-125 mm bores on this largest 4V body. On power loss the spool stays in its last pulsed position with no holding current - it is held by land friction and balanced pressure, not by any magnet. That position hold is not a certified brake: for suspended or fall-protection loads, add a pilot-operated check valve at the cylinder ports or a dedicated mechanical brake.
