About the AirTAC 4V330C-10EI Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, grommet entry (4V330C10EI)
The AirTAC 4V330C-10EI is a 5/3-way double-solenoid pneumatic directional valve that controls double-acting cylinders and rotary actuators. At its center position, all ports are blocked, so the cylinder is held in place when neither solenoid is energised—this closed-center behavior is vital for applications that need mid-stroke stopping under balanced pressure. The valve ships with an AC24V coil drawing 5.0 VA and a pre-wired grommet entry with a 0.5 m flying lead, simplifying DIN-style electrical connection.
Built on the 4V300 aluminium-alloy body with 3/8-inch PT ports and 1/4-inch exhausts, this model delivers an effective area of 21.3 mm² (Cv 1.25) and a maximum cycling rate of 3 cycles per second. The sliding-spool design responds in 0.05 seconds or less, operates on filtered air from 0.15 to 0.8 MPa, and weighs 450 g. IP65-rated protection and an integrated manual override make it a robust choice for machine-tool and clamping circuits.

Where the AirTAC 4V330C-10EI Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, grommet entry (4V330C10EI) Is Used
Mid-Stroke Clamping
The closed-center spool blocks all ports at rest, holding a clamp or press tool in position mid-cycle. This prevents drift on vertical axes while a secondary operation is performed.
Stop-and-Hold Transfer
On a pallet transfer line, the 4V330C-10EI stops a double-acting cylinder at an intermediate inspection station. All ports are sealed, keeping the load stationary until the next step signal arrives.
Machine-Tool Axis Control
Used on a drilling or tapping unit to hold the feed cylinder at a precise depth. The 5/3 closed center maintains balanced pressure on both sides of the piston for stable positioning.
Is the AirTAC 4V330C-10EI Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, grommet entry (4V330C10EI) the Right Valve?
Choose the 4V330C-10EI when your double-acting cylinder needs to pause and hold position at mid-stroke without drifting—the closed center blocks all air paths at rest. If you need the rod to float freely when de-energised, switch to the 4V330E (exhaust center); for a force-balanced center, pick the 4V330P. For smaller bore cylinders around O32-40 mm, the 4V200 series with Cv 1.0 can reduce air consumption; for larger bores above O80 mm, step up to the 4V400 series (Cv 2.82) for faster fill.
When replacing an existing valve, match five points exactly: 4V300 body size, 5/3 closed-center function, 3/8-inch PT port thread, AC24V coil voltage, and grommet-style electrical entry. The 4V330C-10EI can be mounted as a single unit or ganged on a manifold base for multi-cylinder control.
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 4V330C-10EI Solenoid Valve, 5/3-way, closed center, PT3/8, AC24V, grommet entry (4V330C10EI) FAQ
With an effective area of 21.3 mm² (Cv 1.25), this 5/3 closed-center valve suits double-acting cylinders approximately O50 to O80 mm. For a faster 5/2 circuit on the same bore, the 4V310 or 4V320 (Cv 1.65) provides higher flow.
The 'E' in the code designates an AC24V coil drawing 5.0 VA, and the 'I' suffix indicates a grommet-style electrical entry. It comes with a 0.5 m flying lead, allowing you to connect directly to a DIN connector or terminal strip without a separate terminal box.
