About the Airtac 4V300 Solenoid Valve 4V330C-10-B
The AirTAC 4V330C-10B is a 5/3-way double-solenoid valve that directs compressed air to double-acting cylinders and actuators. Its closed-center spool design blocks all ports in the neutral position, holding the cylinder firmly in place when neither solenoid is energized—ideal for applications where a load must not drift during a mid-cycle stop.
Built on the 4V300 aluminum body with 3/8-inch PT ports, this model carries a DC24V coil drawing just 3.0 W. The effective area of 21.3 mm² (Cv 1.25) pairs well with bores in the ~50-80 mm range, while the sub-0.05-second response keeps cycle times tight.

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-B Is Used
Clamping Stations
Holds pneumatic clamps steady at mid-cycle on CNC fixtures or welding jigs, preventing part shift when the valve centers.
Pallet Stop Gates
Controls a lift-and-stop gate on a conveyor line, locking the cylinder in the raised position to safely hold a pallet.
Vertical Press Safety
Keeps a press ram from drifting downward at the neutral point, adding a layer of control for tool-change or setup positions.
Is the Airtac 4V300 Solenoid Valve 4V330C-10-B the Right Valve?
Choose the 4V330C-10B when you need a 5/3 closed-center function on a 3/8-inch ported base. If your cylinder is smaller, the 4V200 series offers a lighter Cv 1.0 alternative; for larger bores, step up to the 4V400 at Cv 2.82. This double-solenoid valve holds its last position on power loss, but remember the closed center means the cylinder is locked at mid-stroke—not just stopped. Match the DC24V coil, PT thread, and terminal-box entry when replacing an existing unit.
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-B FAQ
In the center position, all ports are blocked. The cylinder is held in place and cannot be moved by hand or external force, unlike an exhaust-center valve which would allow it to float.
No, the -B suffix means this specific model requires a 24V DC power supply. Using AC voltage will damage the 3.0 W coil. For AC, choose a model like the 4V330C-10A.
