About the AirTAC 4V330C-10CI Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, grommet entry (4V330C10CI)
The AirTAC 4V330C-10CI is a 5/3-way double-solenoid pneumatic directional valve that directs compressed air to double-acting cylinders and actuators. In its de-energised center position, all ports are blocked, which hydraulically locks the cylinder and holds the load in place at mid-stroke. This specific configuration comes with an AC110V coil drawing 4.5 VA and a grommet-style electrical entry with a 0.5 m flying lead for quick DIN-connector wiring.
Built on the 4V300 aluminum-alloy body, this closed-center valve provides an effective area of 21.3 mm² (Cv 1.25) and suits air cylinders in the ~50–80 mm bore range. The sliding-spool design responds in 0.05 s or less, operates at 0.15–0.8 MPa with 40 µm filtered air, and is rated IP65 for dust and water-jet protection.

Where the AirTAC 4V330C-10CI Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, grommet entry (4V330C10CI) Is Used
Vertical Press Safety Circuits
The closed center blocks all ports at mid-stroke, holding the press ram securely in place during an emergency stop or power interruption, preventing tooling damage.
Material Clamping & Fixturing
Pulse the valve to clamp a part, and the spool holds position without continuous current. The cylinder stays locked, keeping consistent clamping force on the workpiece.
Pallet Stop & Metering Gates
Controls larger-bore stopper cylinders on conveyor lines. The 3/8" ports provide the flow needed for quick actuation, while the closed center holds the gate in position between cycles.
Is the AirTAC 4V330C-10CI Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, grommet entry (4V330C10CI) the Right Valve?
Choose the 4V330C-10CI when your application needs a 3/8" ported 5/3 valve that stops and holds a double-acting cylinder at any point in its stroke—common on vertical press safety circuits or material clamps. If your cylinder bore is under ~40 mm, stepping down to the 4V200 series (Cv 1.0) reduces air consumption; for bores above 80 mm, the 4V400 (Cv 2.82) fills the larger volume faster.
This is a double-solenoid valve, so it only needs a brief pulse to shift and will stay in its last commanded position if power is lost. When replacing an existing valve, match these five points: 4V300 body size, 5/3 closed-center function, 3/8" PT-threaded ports, AC110V coil voltage, and grommet electrical entry.
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-10CI Solenoid Valve, 5/3-way, closed center, PT3/8, AC110V, grommet entry (4V330C10CI) FAQ
With a Cv of 1.25 and a 21.3 mm² effective area, this 5/3 valve is well-matched to double-acting cylinders in the ~50–80 mm bore range. It provides the flow capacity needed for crisp actuation without being oversized for mid-range pneumatic systems.
In the center position, the pressure, exhaust, and both cylinder ports are all blocked. This traps air on both sides of the piston, creating a hydraulic lock that holds the cylinder in place. For true safety-rated load holding, always pair this valve with a pilot-operated check valve or mechanical brake at the cylinder.
