The AirTAC AirTAC 4V330C-10FI Solenoid Valve, 5/3-way, closed center, PT3/8, DC12V, grommet entry (4V330C10FI) is a genuine 5/3-way 5/3 double solenoid — closed center solenoid valve with 330C10FI ports and an effective area of 21.3 mm² (Cv 1.25). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The AirTAC 4V330C-10FI is a 5/3-way double-solenoid pneumatic directional valve that precisely controls double-acting cylinders and actuators. Its closed-center spool design blocks all ports in the neutral position, holding the cylinder firmly in place when both solenoids are de-energized—ideal for mid-stroke stops where drift is unacceptable. This variant ships with a DC12V coil drawing just 2.5 W and a grommet-style electrical entry with a 0.5 m pre-wired flying lead, simplifying installation on mobile or battery-powered equipment.
Built on the 4V300 aluminum-alloy body, this valve provides an effective area of 21.3 mm² (Cv 1.25) and suits pneumatic cylinders in the ~50–80 mm bore range. The sliding-spool design delivers a response time of 0.05 seconds or less, operates on filtered air at 0.15–0.8 MPa, and carries an IP65 protection rating. At 450 g, it can be mounted individually or ganged on a shared manifold base for compact multi-valve assemblies.

Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

The closed-center spool blocks cylinder ports at neutral, letting a fixture or clamp hold a workpiece at any intermediate position without air consumption—critical for gluing, welding, or inspection stations.
Controls double-acting gate cylinders on conveyor lines. The 5/3 center stops the gate mid-swing for precise product sorting, while the DC12V grommet lead suits control panels with low-voltage DC buses.
The 2.5 W DC12V coil and pre-wired grommet entry are a natural fit for liftgates, tail-lift platforms, and service-truck hydraulic-pneumatic circuits where 12 VDC is the primary control voltage.
Choose the 4V330C-10FI when your application demands a 5/3 closed-center function with a low-power DC12V supply and a pre-wired grommet connection. The 4V300 body size bridges the gap between the lighter 4V200 (Cv 1.0) and the larger 4V400 (Cv 2.82), making it the right choice for cylinders in the 50–80 mm bore range. If you need a smaller valve for compact 32–40 mm cylinders, step down to a 4V200 series; for heavy 100–125 mm bore actuators, move up to the 4V400.
For a drop-in replacement, match five key points: the 4V300 body size, the 5/3 closed-center function (30C), the 3/8-inch PT port, the DC12V coil voltage, and the grommet electrical entry. Using a manifold base allows you to combine multiple 4V300 valves with a common supply and exhaust, cutting piping complexity and speeding up assembly.
Quick checklist
With an effective area of 21.3 mm² (Cv 1.25) and a 3/8-inch port, this 4V300-body valve suits double-acting cylinders in the ~50–80 mm bore range. It provides ample flow for mid-size clamping, pressing, and positioning tasks without oversizing the valve.
When both solenoids are de-energized, the spool moves to the center position and blocks the pressure, exhaust, and both cylinder ports. The cylinder stops and holds its current position, prevented from moving by the trapped air. For true load-holding safety in vertical or suspended applications, always add a pilot-operated check valve or mechanical brake at the cylinder ports.
