About the AirTAC 4V330C-10E Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, terminal entry (4V330C10E)
The AirTAC 4V330C-10E is a 5/3-way double-solenoid pneumatic directional valve that directs compressed air to double-acting cylinders and actuators. Its closed-center spool design blocks all ports when both solenoids are de-energized, holding the cylinder in place mid-stroke—a critical feature for applications requiring an intermediate stop without drifting. This model is configured with an AC24V coil drawing 5.0 VA and a PT (Rc) tapered thread on its 3/8-inch supply and output ports.
Built on the 4V300 aluminum-alloy body, this valve delivers an effective area of 21.3 mm² (Cv 1.25) and can cycle at up to 3 times per second. It is well-matched to double-acting cylinders in the ~50-80 mm bore range. The spool shifts in 0.05 seconds or less, and the IP65-rated enclosure with a terminal box entry ensures reliable operation in dusty or wet industrial environments.

Where the AirTAC 4V330C-10E Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, terminal entry (4V330C10E) Is Used
Vertical Press & Clamp Control
Commands a double-acting clamp cylinder to stop and hold pressure mid-stroke for precise part alignment in assembly fixtures, using the closed center to prevent drift before the final press cycle.
Material Handling Stop Stations
Controls a pneumatic gate or stop cylinder on a conveyor line, allowing the actuator to halt at an intermediate position to stage or inspect a workpiece before releasing it to the next zone.
Machine Tool Safety Interlocks
Operates a guard-door cylinder that must pause in a partially open state for chip clearing or tool access, with the closed-center spool blocking airflow to maintain the door's position securely.
Is the AirTAC 4V330C-10E Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, terminal entry (4V330C10E) the Right Valve?
Select the 4V330C-10E when your pneumatic circuit needs a 5/3 closed-center function on a 3/8-inch ported valve. This center condition is ideal for stopping a cylinder mid-stroke and holding its position, but remember that for true, failsafe load-holding, an external pilot-operated check valve is required. For smaller ~32-40 mm bore cylinders, stepping down to a 4V200 series valve (Cv 1.0) is more economical; for larger bores above 80 mm, the 4V400 series (Cv 2.82) provides the necessary flow.
When replacing an existing valve, match all five key points: the 4V300 body size, the 5/3 closed-center (30C) function, the 3/8-inch PT port, an AC24V coil, and the standard terminal box electrical entry. This valve can be used as a single unit or ganged on a manifold base for multi-cylinder control panels.
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-10E Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, terminal entry (4V330C10E) FAQ
With an effective area of 21.3 mm² (Cv 1.25), this 5/3 valve is typically paired with double-acting cylinders in the ~50 to 80 mm bore range. The 3/8-inch port provides sufficient flow for these mid-size actuators in general industrial applications.
When both solenoids are de-energized, the spool moves to its center position where all cylinder ports (A and B) are blocked. This traps air on both sides of the piston, holding the cylinder in place. The AC24V coil draws 5.0 VA and must be de-energized on both sides to achieve this center state.
