About the AirTAC 4V310-10AI Solenoid Valve, 5/2-way, PT3/8, AC220V, grommet entry (4V31010AI)
The AirTAC 4V310-10AI is a 5/2-way single-solenoid directional control valve that directs compressed air to double-acting cylinders and rotary actuators. Its spring-return mechanism requires a constant AC220V signal to hold the shifted position; when power is removed, the internal spring immediately returns the spool to its home state, exhausting the cylinder's previously pressurized side. This makes it a predictable choice for applications where the actuator must default to a safe rest position on power loss.
This configuration ships with a grommet-style electrical entry—a 0.5 m flying lead that simplifies wiring into a DIN connector or terminal strip without needing a separate junction box. With an effective area of 28.0 mm2 (Cv 1.65) and a response time of 0.05 s or below, it suits ~O50-80 mm bore double-acting cylinders. The AC220V coil draws 4.5 VA and the aluminum-alloy body weighs 310 g, rated IP65 for wet and dusty environments.

Where the AirTAC 4V310-10AI Solenoid Valve, 5/2-way, PT3/8, AC220V, grommet entry (4V31010AI) Is Used
Packaging & Palletising
Controls the extend/retract motion of medium-bore clamping and pusher cylinders on case erectors and palletisers. The spring-return action ensures the clamp opens automatically if the E-stop circuit drops the AC220V supply.
Machine Tool Fixtures
Directs air to double-acting work-holding cylinders on CNC mills and drilling stations. The grommet lead connects cleanly to the machine's control panel, and the IP65 body withstands coolant splash.
General Industrial Automation
A workhorse 5/2 valve for assembly lines, test rigs, and material gates. The 28.0 mm2 effective area provides enough flow for ~O50-80 mm cylinders running at 4 cycles per second.
Is the AirTAC 4V310-10AI Solenoid Valve, 5/2-way, PT3/8, AC220V, grommet entry (4V31010AI) the Right Valve?
Choose the 4V310-10AI when you need a single-solenoid 5/2 valve with a pre-wired AC220V lead for direct DIN-rail termination. If your cylinder is smaller than ~O50 mm, stepping down to the 4V200 series (Cv 1.0) reduces air consumption and physical size; for bores above ~O80 mm, the 4V400 series (Cv 2.82) provides the higher flow those larger volumes demand. Within the 4V300 family, a single solenoid (function 10) is the right call when the application requires automatic spring return on power loss—unlike the double-solenoid memory version which stays in its last position.
For a drop-in replacement, match five points exactly: body size (4V300), function (10, single solenoid), port and thread (3/8in PT), coil voltage (AC220V), and electrical entry (grommet with flying lead). If you are building a multi-valve station, this body mounts directly onto a 4V300 manifold base, letting you gang several valves with a common supply and exhaust.
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 4V310-10AI Solenoid Valve, 5/2-way, PT3/8, AC220V, grommet entry (4V31010AI) FAQ
With an effective area of 28.0 mm2 (Cv 1.65), it suits double-acting cylinders in the ~O50-80 mm bore range for typical industrial speeds. The maximum cycling frequency is 4 cycles per second, so it pairs well with moderate-speed automation tasks.
The 'I' suffix (4V310-10AI) means the valve comes with a 0.5 m flying lead exiting through a grommet, ready to wire into a DIN connector or terminal strip. The standard terminal box version (4V310-10A) has screw terminals inside a PG9-gland box. Both use the same 4.5 VA AC220V coil.
