About the AirTAC 4V320-10 Solenoid Valve, 4V300 Series (4V32010H-AM)
The AirTAC 4V32010H-AM is a 5/2-way double-solenoid valve from the 4V300 body family, built to feed compressed air to double-acting cylinders and pneumatic actuators. Each coil pulse shifts the spool, and the valve then keeps that position with no holding current: the spool simply stays where it was last set, retained by land friction and balanced pressure, with no return spring and no magnetic latch. At 3/8in with an effective area of 28.0 mm2 (Cv 1.65), it sits in the flow class that suits approximately Dia 50-80 mm bores.
Response time is 0.05 s or better and the cycling rate reaches 4 cycles per second, so fast stop-start strokes are realistic. The 4V320 body weighs 400 g, accepts 0.15-0.8 MPa working pressure (1.2 MPa proof), carries an IP65 rating and needs no lubrication. This listing is ordered under the full build code 4V32010H-AM, so check the nameplate coil and connector marking when matching it to an existing installation.

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 (4V32010H-AM) Is Used
Palletizer pusher arm
A Dia 63 mm push cylinder, about 159 kgf at 0.5 MPa, sweeping cartons off a roller conveyor: Cv 1.65 fills it quickly, and the memory function parks the arm where it was last pulsed if the PLC signal drops.
CNC machining-center clamps
Switching Dia 80 mm clamp cylinders on a milling fixture, giving roughly 256 kgf at 0.5 MPa; the clamped state survives a controller reboot because the spool holds without any current.
Mixer discharge slide gate
Driving the slide gate under a ribbon mixer or hopper, where 4 cycles per second and a 0.05 s response let the gate reverse rapidly between batch discharges.
Is the AirTAC 4V320-10 Solenoid Valve, 4V300 Series (4V32010H-AM) the Right Valve?
Size both ways before you buy. Step down to the 4V200 body (Cv 1.0) if your cylinder is Dia 50 mm or smaller and pushes roughly 100 kgf at 0.5 MPa; step up to the 4V400 (Cv 2.82) when a Dia 80-100 mm bore needs faster stroke times than Cv 1.65 delivers. Pick the double-solenoid memory version when the actuator must park after a lost signal, a single-solenoid 5/2 when it must spring home, and a 5/3 center type when a neutral state is required. Individual valves can also be banked on a manifold base to share one supply. For replacements, match five points: the 4V300 body, the function (20 = double solenoid), the 3/8in PT port, the coil voltage per the nameplate, and the electrical entry - a terminal box on this build.
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 (4V32010H-AM) FAQ
It is a 5/2-way double-solenoid valve for double-acting cylinders and actuators. Key figures in one place: effective area 28.0 mm2, Cv 1.65, 3/8in ports, working pressure 0.15-0.8 MPa (proof 1.2 MPa), response 0.05 s or less, up to 4 cycles per second, and a 400 g IP65 body. That class suits approximately Dia 50-80 mm bores; a Dia 80 mm cylinder delivers around 256 kgf in push at 0.5 MPa.
There is no spring to return the spool, so once a coil pulse has shifted it, the spool simply stays in that position, held by land friction and balanced pressure, with zero holding current. The hold is mechanical, not magnetic latching, so pulsing either coil is enough to change state. Treat it as position memory, not a safety brake: for a suspended or fall-hazard load, add a pilot-operated check valve at the cylinder ports or a mechanical brake.
