About the AirTAC 4V330C-10C Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, terminal entry (4V330C10C)
The AirTAC 4V330C-10C is a 5/3-way double-solenoid pneumatic directional valve that directs compressed air to double-acting cylinders and actuators, with a closed center position that blocks all ports when both coils are de-energised. This configuration allows the cylinder to hold its position mid-stroke, making it suitable for applications where the load must pause without drifting. The valve is built on the 4V300 body platform with a 3/8-inch PT inlet and outlet, while the exhaust ports are 1/4-inch.
With an effective area of 21.3 mm² and a Cv of 1.25, this 5/3 valve suits cylinders approximately 50 to 80 mm in bore. This specific SKU is configured for an AC110V coil drawing 4.5 VA, connected via the standard terminal box entry. The aluminum-alloy body weighs 450 g and responds in 0.05 seconds or less. It operates on a 0.15-0.8 MPa air supply filtered to 40 µm and carries an IP65 protection rating, so it can be used in dusty or washdown environments without an additional enclosure.

Where the AirTAC 4V330C-10C Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, terminal entry (4V330C10C) Is Used
Mid-Stroke Clamping Fixtures
The closed-center spool holds a double-acting clamp cylinder in position when the valve is de-energised, preventing drift during machining or welding operations on workpieces up to 80 mm bore.
Stop-and-Hold Material Handling
Controls lift-and-carry transfer units where the actuator must pause mid-cycle. The blocked center keeps the load suspended while the conveyor indexes, with a pilot-operated check valve recommended for vertical safety.
Press and Forming Machines
Directs a double-acting press cylinder with a defined hold at center. The AC110V coil fits standard factory power, and the 3/8-inch port delivers sufficient flow for medium-bore pneumatic presses.
Is the AirTAC 4V330C-10C Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, terminal entry (4V330C10C) the Right Valve?
Choose the 4V330C-10C when your application requires a 3/8-inch ported valve that can stop and hold a double-acting cylinder at mid-stroke. The closed-center spool blocks inlet, outlet, and exhaust ports in the neutral position, which is useful for clamping or pressing sequences where the actuator must pause under pressure. If your cylinder is smaller than 50 mm bore, the 4V200 series (Cv 1.0) may offer a more compact and economical fit; for bores above 80 mm, stepping up to the 4V400 (Cv 2.82) will provide faster filling and higher cycle rates.
When replacing an existing valve, match five points: the 4V300 body size, the 5/3 closed-center function (30C), the 3/8-inch port with PT thread, the AC110V coil voltage, and the terminal-box electrical entry. This valve can be mounted individually or on a common manifold base. Note that the 5/3 center position reduces the effective flow area compared to a 5/2 model, so factor the 21.3 mm² area into your speed calculations.
Quick checklist

- ✓ 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-10C Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, terminal entry (4V330C10C) FAQ
When both solenoids are de-energised, the spool moves to the center position and blocks the pressure, cylinder A, cylinder B, and exhaust ports. This traps air on both sides of a double-acting cylinder, holding the piston in place. It is not a safety lock; for suspended loads, add a pilot-operated check valve or mechanical brake.
Yes, the AC110V coil is rated for both 50 Hz and 60 Hz operation. The inrush is 4.5 VA and the holding power is lower. Ensure your supply voltage stays within ±10% of the rated 110V to avoid coil burnout or sluggish shifting.
