About the AirTAC 4V320-10 Solenoid Valve, 4V300 Series (4V32010A-AM-W)
The AirTAC 4V32010A-AM-W is a 5/2-way double-solenoid directional valve built on the 4V300 body, sized for 3/8in PT ports and rated at an effective area of 28 mm2 (Cv 1.65). Because both solenoids position the spool, the valve is a true memory type: it stays in whichever position it was last pulsed to, held by land friction and balanced pressures with no spring and no holding current - it is not magnetically latched, so a momentary pulse is all the control circuit needs.
This specific build carries two factory options. The -W suffix makes it an external-pilot valve: pilot air enters through a separate pilot port instead of being tapped internally from the main line, so switching stays dependable on low main-line pressure or in low-pressure circuits. The -AM suffix fits an AMISCO (Italian) solenoid coil in place of the standard coil on the AC220V, terminal-box version; the valve function and 400 g assembly weight are unchanged, but ask us to confirm the exact AMISCO coil electrical rating before ordering. Like every 4V300 valve it responds in 0.05 s or less, carries IP65 protection, and comfortably serves double-acting cylinders in the ~O50-80 mm bore range.

Flow & Coil Options
| Effective area | 28.0 mm² |
|---|---|
| Flow coefficient | Cv 1.65 |
| 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 |

Where the AirTAC 4V320-10 Solenoid Valve, 4V300 Series (4V32010A-AM-W) Is Used
Press and clamp actuation
Feeds 3/8in-lineserving larger double-acting press and clamp cylinders around O50-80 mm, with Cv 1.65 flow to keep stroke times short at up to 4 cycles per second.
Low-pressure pilot circuits
The external-pilot (-W) construction takes pilot air from its own port, so the valve keeps shifting cleanly on machines where main-line pressure runs low or vacuum handling is involved.
Material handling actuators
Positions grippers, lifts and conveyor stopper cylinders on packaging and palletising lines, retaining the last pulsed state through control-power dips without drawing holding current.
Is the AirTAC 4V320-10 Solenoid Valve, 4V300 Series (4V32010A-AM-W) the Right Valve?
Match this Cv 1.65 class to your bore: drop to the 4V200 (Cv 1.0) for smaller cylinders, or move up to the 4V400 (Cv 2.82) when a larger bore demands more flow. Choose a 20-type double solenoid when you want the actuator to hold its last pulsed state through a power cut; pick the 10-type if you need a spring to return the spool whenever the signal drops, or a 30C/E/P 5/3 version when a definite center condition matters. Run one valve stand-alone or gang several on an integrated manifold base to cut piping. When replacing, verify all five points: 4V300 body, function 20, 3/8in PT ports, AC220V coil, terminal entry - plus the two option codes, since only another -W external-pilot unit will behave the same on a low-pressure supply and only another -AM unit will share the AMISCO coil.
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 4V320-10 Solenoid Valve, 4V300 Series (4V32010A-AM-W) FAQ
It is a 5/2 double-solenoid valve for double-acting cylinders and actuators, pressurising one port while exhausting the other. With an effective area of 28 mm2 (Cv 1.65) and a 3/8in PT main port, it suits roughly O50-80 mm bores and switches up to 4 cycles per second at 0.15-0.8 MPa. Single-acting cylinders need a 3/2 valve, not this model.
-AM means the AC220V coil is an AMISCO (Italian) unit rather than the standard coil; -W means external pilot, so pilot air is supplied through a separate port. Mechanically it replaces a 4V320-10A one-for-one (same 4V300 body, 5/2 memory function, 3/8in PT, 400 g), but on a -W valve you must pipe the pilot port, and the AMISCO coil rating should be confirmed with us before reuse.
