About the AirTAC 4V320-10FI Solenoid Valve, 5/2-way, PT3/8, DC12V, grommet entry (4V32010FI)
The 4V320-10FI is a 5/2-way double-solenoid pneumatic directional valve built on the 4V300 aluminum-alloy body platform. It directs compressed air to double-acting cylinders and actuators using a memory-spool design: a momentary pulse to coil 14 shifts the spool and stays there after power is removed, held by land friction and balanced pressure. A pulse to coil 12 returns it. This specific configuration ships with a DC12V coil (2.5 W) and a grommet-style electrical entry that includes a 0.5 m pre-wired flying lead, simplifying installation where a terminal box is impractical.
The 4V300 flow class delivers an effective area of 28.0 mm² (Cv 1.65), which suits pneumatic cylinders in the ~O50-80 mm bore range for typical industrial speeds. Response time is 0.05 seconds or below, and the IP65-rated enclosure keeps out dust and low-pressure water jets. The valve operates on filtered, non-lubricated air at 0.15-0.8 MPa and can be banked into an integrated manifold group when multiple axes are controlled from one supply.

Where the AirTAC 4V320-10FI Solenoid Valve, 5/2-way, PT3/8, DC12V, grommet entry (4V32010FI) Is Used
Packaging & Palletizing
Drives large-bore clamp and pusher cylinders on case packers and palletizers. The memory function holds the cylinder in place between cycles without coil heating, while the 28.0 mm² effective area provides the flow needed for rapid advance and retract strokes.
Machine Tool Clamping
Controls double-acting clamping cylinders on CNC fixtures and milling beds. A momentary signal engages the clamp and the spool stays put, so the valve draws zero holding current during the entire machining cycle, reducing cabinet heat.
Liftgate & Tilt-Tray Sorters
Operates tilt-tray actuators and liftgate cylinders on logistics sortation equipment. The DC12V grommet coil suits battery-powered or low-voltage DC control panels, and the IP65 protection handles dusty warehouse and dock environments.
Is the AirTAC 4V320-10FI Solenoid Valve, 5/2-way, PT3/8, DC12V, grommet entry (4V32010FI) the Right Valve?
Choose the 4V320-10FI when your application needs a 5/2 valve that holds its last spool position without a continuous electrical signal—ideal for energy-sensitive circuits or where a control system only provides momentary outputs. The 3/8-inch PT port matches common Rc-tapered piping, and the DC12V coil with grommet lead-out is a direct fit for mobile equipment or smaller DC-powered machines. If your cylinder is below O40 mm, the 4V200 series (Cv 1.0) may offer a more compact, lower-cost solution; for bores above O80 mm, step up to the 4V400 (Cv 2.82) for faster filling. When replacing an existing valve, match all five points: 4V300 body size, double-solenoid 5/2 function, 3/8-inch port thread, DC12V coil voltage, and grommet electrical entry. For a spring-return action that fails to a known state on power loss, select the single-solenoid 4V310 variant instead.
Quick checklist

- 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 4V320-10FI Solenoid Valve, 5/2-way, PT3/8, DC12V, grommet entry (4V32010FI) FAQ
With an effective area of 28.0 mm² (Cv 1.65), the 4V300 body is well-matched to cylinders in the ~O50-80 mm bore range for general industrial stroking speeds. Smaller cylinders will cycle faster; larger bores will move more slowly and may benefit from stepping up to the 4V400 series (Cv 2.82). Always confirm the cylinder’s air consumption and required cycle time against the valve’s Cv.
The spool is shifted by a momentary electrical pulse and remains in its last commanded position through land friction and balanced pressure—no spring, no holding current, and no magnetic latching. While this provides a stable position after a power loss, it is not a safety-rated load-holding device. For applications involving suspended or vertical loads, a pilot-operated check valve or mechanical brake at the cylinder ports is required to prevent drift.
