About the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10H-AM)
This 4V330C10H-AM belongs to the AirTAC 4V300 family and works as a 5/3 closed-center, double-solenoid directional valve. Each coil pulse shifts the spool; when both are de-energised, springs return it to a position where every port - supply, both cylinder ports and both exhausts - is blocked. That is what lets a double-acting actuator sit still between strokes instead of venting or reloading. Flow capacity sits at 21.3 mm2 effective area, Cv 1.25, with a 3 cycles per second limit on the 5/3 spool.
The valve carries 3/8 in PT tapered connections (1/4 in exhausts) and a terminal-box entry, and the aluminium body tips the scale at 450 g. Note on the coil: standard 4V300 voltage codes are A (AC220V), C (AC110V), E (AC24V), B (DC24V) and F (DC12V) - the H suffix on this part number is not a standard listed code, so confirm the exact coil voltage with us before ordering. Operating band is 0.15-0.8 MPa and the valve reacts within 0.05 s of the switching signal.

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 |
| Manual override | Yes (locking / non-locking) |
Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Where the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10H-AM) Is Used
CNC fixture workholding
Clamping tall or awkward workpieces on a machining-center fixture between cuts: the closed center pins the clamp cylinder in place so vibration does not walk it off position, while the 450 g aluminium body keeps the fixture-side manifold easy to mount.
Pallet elevator on a packaging line
A double-acting lift cylinder raising pallets to an intermediate transfer height pauses there the moment both solenoids drop. Because the load is vertical, pair the valve with pilot-operated check valves at the cylinder ports so holding never depends on air pressure alone.
Endurance test rig for latch mechanisms
Cycling door-latch or hinge samples on a quality lab rig demands repeated mid-stroke stops; the 3 cycles per second rating and 0.15-0.8 MPa operating band cover the duty, and the manual override lets technicians jog the actuator with the controls powered down.
Is the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10H-AM) the Right Valve?
Check the class against your actuator before ordering. Downward: an O50 cylinder developing around 25 kgf of push at 0.5 MPa is better served by the 4V200 body (Cv 1.0). Upward: O80 bores pushing about 256 kgf, or anything beyond the ~O50-80 mm range, deserves the 4V400 at Cv 2.82. Within the 4V300 line, pick the 5/2 models 4V310/4V320 (Cv 1.65, 4 cycles/s) when no center stop is required, or the 4V330C-08 variant if your plumbing is built around 1/4 in ports. One valve per actuator is normal; for machines with several cylinders, stack the valves on a shared 4V300 manifold base and save on fittings and piping.
Ordering a replacement? Verify all five: 4V300 body, 30C closed-center function, 3/8 in port on PT thread, the coil voltage, and terminal versus grommet entry.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed

- ✓ 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 (4V330C10H-AM) FAQ
Standard AirTAC codes are A = AC220V (4.5 VA), C = AC110V (4.5 VA), E = AC24V (5.0 VA), B = DC24V (3.0 W) and F = DC12V (2.5 W), each with a terminal box or a 0.5 m grommet lead. The H suffix on this SKU is not one of the listed 4V300 coil codes, so please confirm the intended voltage before placing the order so the coil matches your control circuit.
It directs compressed air to double-acting cylinders and rotary actuators in the ~O50-80 mm class. Defining figures in one place: effective area 21.3 mm2 (Cv 1.25) on the 5/3 spool, response 0.05 s or below, operating pressure 0.15-0.8 MPa with 1.2 MPa proof pressure, maximum 3 cycles per second, closed center holding all ports blocked at rest, 3/8 in PT ports (1/4 in exhausts), IP65 housing and a 450 g body.
