About the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10A-AM)
The 4V330C-10A-AM is a 5/3-way double-solenoid directional valve in the AirTAC 4V300 body class, wired for AC220V through a conventional terminal box and fitted with a factory AMISCO solenoid coil. At the center position all five ports are blocked, so a double-acting cylinder connected to ports A and B simply freezes where it stands - neither side vents nor pressurises until you pulse the other solenoid. Flow capacity sits at 21.3 mm2 effective area (Cv 1.25), the rating AirTAC assigns to the 5/3 spool in this body, which pairs naturally with cylinders in the roughly O50-80 mm bore range.
Two datasheet facts matter when specifying this valve: activation time is 0.05 s or better, and the complete 5/3 assembly weighs 450 g, so manifold plates and mounting brackets stay light. The AMISCO coil substitution changes nothing about the pneumatic performance - body, spool, ports and pressure range (0.15-0.8 MPa working, 1.2 MPa proof) are identical to the standard 4V330C-10A - but the exact electrical rating of the AMISCO coil is not covered by the standard 4V300 data, so confirm the coil VA figure with us before ordering control gear. Filtered air through a 40 um element and IP65 (DIN40050) protection apply as standard; lubrication is not required.

Where the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10A-AM) Is Used
Press and forming stations
A closed-center 5/3 valve lets a pneumatically driven press or forming slide pause mid-stroke between solenoid pulses, holding the cylinder stationary until the next command without venting the working lines.
Multi-cylinder machine tool fixtures
Clamping and positioning cylinders around a machine tool benefit from mid-stroke stops; several 4V330C valves on a shared manifold base keep the air preparation and wiring to one point.
Material handling positioners
Handling arms and product stops on conveyors or palletisers can halt at an intermediate position with both cylinder ports blocked, resuming travel when either solenoid on the AC220V supply is pulsed.
Is the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10A-AM) the Right Valve?
Size first, then function. If your cylinder is a smaller bore and Cv 1.0 (the 4V200 class) already gives the speed you need, step down; if you are pushing a larger bore and want Cv 2.82, move up to the 4V400. The 4V300 sits between them, and within it the 5/3 spool trades some flow (Cv 1.25 versus 1.65 on the 5/2) for the mid-position you need: closed center to hold position, exhaust center to float, pressure center to pre-charge both sides. Choose the double-solenoid closed version when the actuator must stop and stay put between commands rather than spring back to a rest state. A single valve on a foot bracket suits one-off stations; bolt several onto a manifold base when a machine runs a bank of cylinders from one supply.
For a like-for-like replacement match five points, in this order: body size (4V300), function (5/3 closed center, double solenoid), port and thread (3/8in PT tapered), coil voltage (AC220V), and electrical entry (terminal box). Add the -AM suffix only if you specifically want 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 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10A-AM) FAQ
It directs compressed air to double-acting cylinders and actuators in the approximate O50-80 mm bore range. As a 5/3-way valve in the 4V300 body it flows 21.3 mm2 effective area (Cv 1.25) with a maximum switching frequency of 3 cycles per second, and activation takes 0.05 s or less. AirTAC publishes flow as a chart rather than a single figure, so use the Cv value for sizing comparisons.
No. The closed center blocks ports A and B, so the cylinder stops where it is, but spool-valve sealing is not a certified holding device - for suspended or fall-hazard loads add a pilot-operated check valve at the cylinder ports or a mechanical brake. On the electrical side, this SKU carries an AMISCO coil on the AC220V terminal-box configuration; its exact VA rating is not covered by the standard AirTAC data, so please confirm it with us before specifying your control transformer.
