About the Airtac 4V300 Solenoid Valve 4V330C-10-A
The AirTAC 4V330C-10A is a 5/3-way double-solenoid pneumatic directional valve that directs compressed air to double-acting cylinders and actuators. When both solenoids are de-energised, the closed-center spool blocks all ports, holding the cylinder in its last position. This makes it a strong fit for mid-stroke stops on presses, clamps, and vertical-axis jigs where drift must be minimised—though for suspended loads a separate pilot-operated check valve is still required.
Built on the 4V300 aluminium body, this AC220V terminal-box model weighs 450 g and delivers an effective area of 21.3 mm² (Cv 1.25). With a maximum frequency of 3 cycles per second and a response time of 0.05 s or below, it comfortably paces cylinders in the ~Ø50–80 mm range. The coil draws 4.5 VA, and the IP65-rated housing keeps dust and low-pressure jets out, so it holds up on busy factory floors.

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 |

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 4V300 Solenoid Valve 4V330C-10-A Is Used
Clamping & Fixturing Stations
The closed-center spool locks air in both cylinder ports, keeping a clamp or fixture firmly in place during machining or welding cycles without needing constant solenoid power.
Vertical-Axis Stops & Lifts
Holds a vertical cylinder at mid-stroke for part transfer or inspection. The 5/3 closed center prevents creep, though a pilot check valve is recommended for safety-rated load holding.
Press & Forming Equipment
Controls larger double-acting cylinders on pneumatic presses. The AC220V coil and 3/8" ports supply the flow needed for Ø50–80 mm bore actuators running at 3 cycles per second.
Is the Airtac 4V300 Solenoid Valve 4V330C-10-A the Right Valve?
Step up to this 4V330C-10A when your application needs a 5/3 closed-center function on a 3/8" port—the spool blocks inlet, outlet, and exhaust at rest, giving you a deliberate mid-stroke hold without continuous power. If you are driving a smaller Ø32–40 mm cylinder, the 4V200 series (Cv 1.0) is often a better match; for bores above Ø100 mm, the 4V400 (Cv 2.82) provides the extra flow. Choose a single-solenoid 4V310 when you only need two end positions with spring return, or a double 5/2 4V320 when you want a memory function that stays put on power loss. This valve can be mounted individually or on a manifold base, and when replacing an existing unit, match all five points: 4V300 body, 5/3 closed-center function, 3/8" PT port, AC220V coil, and terminal-box entry.
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 4V300 Solenoid Valve 4V330C-10-A FAQ
With an effective area of 21.3 mm² (Cv 1.25), it typically suits double-acting cylinders in the Ø50–80 mm range. For smaller Ø32–40 mm bores, a 4V200 valve (Cv 1.0) is often more economical; for bores above Ø100 mm, consider stepping up to the 4V400 series (Cv 2.82).
When both solenoids are off, the spool moves to the center position and blocks all ports (P, A, B, EA, EB). This traps air on both sides of the cylinder, holding the piston near its current position. It is not a safety-rated holding brake—if the load must never drop, add a pilot-operated check valve at the cylinder ports.
