About the AirTAC 4V310-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V31010CI)
The AirTAC 4V310-10CI is a single-solenoid, 5/2-way pneumatic directional valve that directs compressed air to double-acting cylinders and actuators. It requires a constant AC110V signal to hold the shifted position; de-energising the coil instantly returns the spool to its home state via a mechanical spring, making it a safe default for cycles where the actuator must retract or stop on power loss. This model arrives pre-wired with a 0.5-metre grommet-style flying lead, speeding up DIN-rail panel builds.
With a 28.0 mm² effective area and a Cv of 1.65, the 4V310-10CI suits bore sizes from roughly 50 to 80 mm. The aluminium-alloy body keeps weight to 310 grams, and the spool shifts in 0.05 seconds or less. Operating on a 40 µm filtered air supply at 0.15–0.8 MPa, the valve carries IP65 protection and class-B insulation, so it handles washdown-adjacent machine zones reliably.

Where the AirTAC 4V310-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V31010CI) Is Used
Palletising & Conveyor Diverters
Drives the pneumatic gates and pushers on packaging lines. The spring return guarantees the diverter retracts when AC power drops, preventing a lane blockage.
Machine Tool Clamping
Controls a double-acting clamp on a CNC fixture. The 0.05 s shift time and Cv 1.65 flow give a fast, firm grip, while the spring return releases the part on an E-stop.
Baling & Compaction Presses
Shifts a large-bore ram cylinder in recycling balers. The AC110V grommet coil simplifies wiring inside a crowded control panel, and the 310 g body mounts easily on a manifold.
Is the AirTAC 4V310-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V31010CI) the Right Valve?
Choose the 4V310-10CI when your double-acting cylinder falls in the 50–80 mm bore range and you need a spring-return action driven by an AC110V supply. If the cylinder is smaller, the 4V200 body (Cv 1.0) often gives a crisper response; for bores above 80 mm, step up to the 4V400 (Cv 2.82) to keep cycle times short. The single-solenoid design is ideal for two-position duties where the valve must default to a known state when the machine e-stops.
This SKU specifies a 3/8-inch PT (Rc) port with an AC110V coil and a grommet electrical entry. When replacing an existing valve, match all five points: 4V300 body size, 5/2 single-solenoid function, 3/8-inch PT thread, 110 V AC coil, and the grommet lead-out. For manifold mounting, confirm the base station matches the 4V300 footprint and port spacing.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center

- ✓ 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 4V310-10CI Solenoid Valve, 5/2-way, PT3/8, AC110V, grommet entry (4V31010CI) FAQ
Its 28.0 mm² effective area (Cv 1.65) comfortably drives double-acting cylinders in the 50–80 mm bore range at typical plant pressures. For a 100 mm bore running fast cycles, consider the 4V400 series to avoid speed loss.
Yes. The ‘CI’ suffix means the valve comes with a DIN-style grommet and a 0.5-metre flying lead, ready to wire into a terminal strip. The coil is rated AC110V, 4.5 VA, and the assembly maintains the full IP65 rating.
