About the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-AM)
The AirTAC 4V330C10C-AM is a 5/3-way double-solenoid directional valve in the 4V300 body class, built with PT 3/8" ports and an AC110V coil on a terminal-box entry. This -AM variant comes fitted with an AMISCO (Italian) solenoid coil instead of the standard coil; the valve body, flow path and 3/8" PT connections are unchanged, and the ordered AC110V voltage still applies. At center, the closed-center spool blocks all five ports, so a connected double-acting cylinder holds its position the moment both solenoids are de-energised. Flow capacity is 21.3 mm2 effective area (Cv 1.25), a good match for cylinders in the ~O50-80 mm bore range.
Switching between the two solenoids shifts the spool in 0.05 s or less, and the middle position gives you a true three-state machine: extend, retract, or stop-and-hold. The aluminum-alloy body weighs 450 g and carries an IP65 (DIN40050) terminal box, so it shrugs off washdown dust and splash on the machine frame. As with every 4V300 valve, no lubrication is needed, the air must pass a 40 um filter, and the unit bolts onto a base for manifold grouping. Note that the exact electrical rating of the AMISCO coil (VA figure) is not published in our data, so confirm it with us when you plan your circuit.

Where the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-AM) Is Used
Mid-stroke stop on a press or forming tool
The closed-center spool blocks pressure, exhaust and cylinder ports at once, so an O50-80 mm double-acting cylinder halts and holds where the last pulse left it.
Multi-station clamping on a manifold
Bolt several 4V330C units onto a common base and run each clamp independently, with Cv 1.25 per station giving brisk cycles at up to 3 strokes per second.
Position-holding lifts in material handling
AC110V control through the IP65 terminal box suits cabinet-wired conveyor and lifting fixtures; add pilot-operated check valves at the cylinder ports where a suspended load must be guaranteed against drop.
Is the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-AM) the Right Valve?
Size the valve to the cylinder first. The 4V300 class at Cv 1.25 covers ~O50-80 mm bores; drop to the 4V200 (Cv 1.0) for smaller actuators, or step up to the 4V400 (Cv 2.82) when the bore or stroke speed outgrows this body. Among 5/3 options, pick closed center (this valve) to hold a cylinder at mid-stroke, exhaust center to let it float freely, or pressure center to park both sides under pressure. One valve on a foot-mounted body works for single-station use; add a manifold base when several stations share one supply.
For an exact replacement of 4V330C10C-AM, match five things: 4V300 body size, 5/3 closed-center double-solenoid function, 3/8" PT port thread, AC110V coil voltage, and terminal-box electrical entry. If your original coil was the AMISCO-fitted -AM version, order the same suffix so the coil brand matches what is already wired on the machine.
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 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-AM) FAQ
It directs compressed air to double-acting cylinders and actuators, with an effective area of 21.3 mm2 (Cv 1.25) that suits roughly O50-80 mm bores. The -AM suffix means the valve ships with an AMISCO (Italian) solenoid coil fitted at the factory; flow, ports and 5/3 closed-center function are identical to the standard 4V330C-10C. The AMISCO coil's exact VA rating is not in our published data, so confirm it with us before sizing your power supply.
It blocks all five ports, trapping air on both sides of the double-acting cylinder so the piston stays at its last commanded station. The spool itself is held by land friction and balanced pressure, not a spring and not a magnet. This is a positional stop, not a certified safety brake: for suspended or fall-risk loads, fit a mechanical brake or pilot-operated check valves at the cylinder ports as well.
