About the AirTAC 4V330P-10AI Solenoid Valve, 5/3-way, pressure center, PT3/8, AC220V, grommet entry (4V330P10AI)
The AirTAC 4V330P-10AI is a 5/3-way double solenoid valve engineered to control double-acting cylinders and actuators with a pressure center configuration. When both solenoids are de-energized, the spool shifts to its center position where both cylinder ports are simultaneously pressurized, allowing for unique force-balancing or clamping applications that require continuous pressure without directional movement. This model is pre-wired with a 0.5 m flying lead via a grommet entry and operates on an AC220V coil drawing 4.5 VA.
Built on the 4V300 aluminum-alloy body, it delivers an effective area of 21.3 mm² (Cv 1.25) and suits pneumatic cylinders in the ~50-80 mm bore range. The sliding-column spool responds in 0.05 seconds or less, and with an IP65 protection rating and a maximum cycling rate of 3 cycles per second, it is a robust choice for industrial tasks where a pressure-center function is required.

Where the AirTAC 4V330P-10AI Solenoid Valve, 5/3-way, pressure center, PT3/8, AC220V, grommet entry (4V330P10AI) Is Used
Balanced Clamping Fixtures
The pressure center applies equal force to both sides of a cylinder at rest, making it ideal for balanced clamping systems that must grip a workpiece without drifting in either direction.
Tensioning and Pressing
In web tensioning or light press applications, the 4V330P-10AI maintains a static pressure state at center, preventing material slack or unintended release when the directional signal is removed.
Machine Tool Actuation
Use this valve on machine tools requiring a mid-stroke pressure hold, such as a tool changer or a positioning arm that must resist external forces without active directional input.
Is the AirTAC 4V330P-10AI Solenoid Valve, 5/3-way, pressure center, PT3/8, AC220V, grommet entry (4V330P10AI) the Right Valve?
Select the 4V330P-10AI when your double-acting cylinder circuit needs both sides to remain under pressure at idle, such as in a balanced clamping or tensioning fixture. This 5/3 pressure-center valve fits between the smaller 4V200 series (Cv 1.0) for lighter loads and the 4V400 series (Cv 2.82) for larger bores. The double solenoid design holds its last position on power loss, but the pressure center provides a defined, powered state at rest.
For a drop-in replacement, match five key points: the 4V300 body size, the 5/3 pressure-center function (30P), the 3/8-inch PT port, the AC220V coil voltage, and the grommet electrical entry. This valve can be mounted individually or integrated into a manifold base for multi-valve assemblies.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center

- ✓ 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 4V330P-10AI Solenoid Valve, 5/3-way, pressure center, PT3/8, AC220V, grommet entry (4V330P10AI) FAQ
In the center position, both the A and B cylinder ports are pressurized simultaneously. This differs from a closed center (which blocks all ports) and an exhaust center (which vents both ports to atmosphere), making it suitable for applications needing balanced force at rest.
With an effective area of 21.3 mm² (Cv 1.25), this 5/3 valve is typically paired with double-acting cylinders in the ~50-80 mm bore range. For precise sizing, match the valve's Cv to the cylinder's air consumption at your operating speed and pressure.
