About the AirTAC 4V320-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V32010CI)
The AirTAC 4V320-10CI is a double-solenoid 5/2-way pneumatic directional valve that controls double-acting cylinders and actuators with a memory function. A momentary pulse to either coil shifts the spool, and it remains locked in that last-commanded position even when power is removed—held securely by internal friction and balanced pressure, not by a spring or magnet. This behavior makes it ideal for material-transfer stations and clamping circuits where the actuator must stay put if an E-stop interrupts control power.
Pre-wired with a 0.5 m flying lead through a DIN-style grommet entry, this model simplifies electrical installation in cable-chain or wet environments while maintaining an IP65 protection rating. The AC110V coil draws 4.5 VA, and the valve body delivers a 28.0 mm² effective area (Cv 1.65), suiting double-acting cylinders in the ~50–80 mm bore range. At 400 g, it responds in 0.05 s or less and can cycle up to 4 times per second.

Where the AirTAC 4V320-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V32010CI) Is Used
Material Transfer Stations
The memory function holds a transfer arm or pusher in place during an E-stop event, preventing product damage and allowing a safe restart without re-homing the actuator.
Clamping & Fixturing
Pulse the clamp closed and the 4V320-10CI stays put with no holding current, keeping parts secure during machining or welding cycles even if the PLC output drops.
Bulk Bag Filling & Sealing
Controls double-acting gate cylinders on fill heads. The grommet lead and IP65 body stand up to dusty, washdown-prone packaging lines while the AC110V coil matches common plant voltage.
Is the AirTAC 4V320-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V32010CI) the Right Valve?
Choose the 4V320-10CI when your application needs a 5/2 valve that holds its last position after a power loss, eliminating the need for a continuous holding signal. The 3/8-inch PT ports and Cv of 1.65 place it in the sweet spot for mid-bore pneumatic cylinders; step down to a 4V200 series (Cv 1.0) for smaller actuators under 40 mm bore, or move up to a 4V400 (Cv 2.82) when driving cylinders above 100 mm. The AC110V grommet configuration is particularly suited to North American machinery panels where a flying lead is preferred over a terminal box.
For a drop-in replacement, match five points exactly: the 4V300 body size, the double-solenoid memory function (4V320), the 3/8-inch port size, the AC110V coil voltage, and the grommet electrical entry. If you are building a multi-valve manifold, verify that the sub-base and gasket kit are compatible with the 4V300 series; the same valve can be mounted individually or ganged on a common base for centralized air supply.
Quick checklist

- ✓ 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 4V320-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V32010CI) FAQ
With a 28.0 mm² effective area (Cv 1.65), this valve is a strong match for double-acting cylinders in the ~50–80 mm bore range. It provides crisp actuation at the 4 c/s max frequency, making it suitable for moderate-speed pick-and-place and clamping duties.
The 4V320 spool stays in its last pulsed position through land friction and balanced air pressure—no spring return and no magnetic latching. While this holds the actuator in place during a power loss, it is not a safety-rated holding brake. For suspended or vertical loads, always add a pilot-operated check valve or a mechanical brake at the cylinder ports.
