About the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-AM)
The 4V330E10A-AM is a 5/3-way double solenoid pilot valve with an exhaust center, built on the AirTAC 4V300 body. When both coils are de-energised, the cylinder ports A and B vent to exhaust, so a double-acting cylinder is left free to move by hand, gravity or external force instead of being locked. A brief pulse on either solenoid shifts the spool and pressurises one cylinder side while the other exhausts. This -AM version ships with an Italian AMISCO coil fitted at the factory on the AC220V winding with terminal-box entry; the valve is otherwise identical to the standard 4V330E-10A.
Flow sits in the 4V300 mid-large class: an effective area of 21.3 mm2 (Cv 1.25) and a maximum cycling rate of 3 cycles per second, which pairs naturally with cylinder bores of roughly O50-80 mm. The complete valve weighs 450 g, switches in 0.05 s or less, and carries IP65 protection on the terminal housing. AirTAC publishes flow as a chart rather than a single figure, so size your air consumption from the Cv above.

Flow & Coil Options
| Effective area | 21.3 mm² |
|---|---|
| Flow coefficient | Cv 1.25 |
| 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 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-AM) Is Used
Manual repositioning on machine tools
Exhaust center leaves the cylinder ports vented, so an operator or tool setter can slide the workholder or stop freely to a new position before re-clamping with a pulse signal.
Drifting stops and gates on handling lines
On packaging and conveyor runs, a floating actuator lets product push past a soft gate or allows manual jog of a diverting cylinder when the line is stopped and de-energised.
Multi-valve manifold stations
The 4V300 body mounts on a common base, so several 4V330E10A-AM valves can form one grouped manifold feeding O50-80 mm bores across a production station.
Is the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-AM) the Right Valve?
Match the 4V300 class against your bore: the 4V200 (Cv 1.0) suits smaller cylinders and saves panel space, while the 4V400 (Cv 2.82) is the right step up for bores beyond about O80 mm where you need higher piston speed. Within the function choice, take the 30E exhaust center when the actuator should drift or be positioned by hand at rest, the 30C closed center when it must hold its position, or the 30P pressure center when both sides need balanced air. One valve can screw straight onto a manifold base if you are building a multi-station group.
For an exact replacement, confirm five points: 4V300 body size, the 5/3 exhaust-center function (30E), PT 3/8 ports, AC220V coil, and terminal-box electrical entry. Then check the -AM suffix, which is the AMISCO coil option and should be carried over on any reorder.
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 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-AM) FAQ
It is a 5/3-way valve for double-acting cylinders and pneumatic actuators, not for single-acting types. The 4V300 body gives an effective area of 21.3 mm2 (Cv 1.25) with a 3 cycle per second maximum, and it is typically matched to bores of about O50-80 mm. Use the published AirTAC flow chart for exact air consumption figures.
The -AM suffix means this valve is fitted with an Italian AMISCO coil instead of the standard one; the valve function, PT 3/8 ports and flow are unchanged. It is wound for AC220V with terminal-box entry. Because our listing does not state the AMISCO coil's VA rating, please confirm the exact electrical rating with us before ordering spares.
