About the AirTAC 4V310-10E Solenoid Valve, 5/2-way, PT3/8, AC24V, terminal entry (4V31010E)
The AirTAC 4V310-10E is a 5/2-way single-solenoid directional control valve built on the 4V300 body, directing compressed air to double-acting cylinders and rotary actuators. Its spool is shifted by energising the AC24V coil and returned by a mechanical spring when the signal is removed—making it a dependable choice for circuits where the valve must default to a known position on power loss.
With an effective area of 28.0 mm2 (Cv 1.65) and a response time of 0.05 s or less, this 3/8in ported valve suits ~O50–80 mm bore cylinders in general industrial automation. The AC24V coil draws 5.0 VA, and the IP65-rated terminal-box entry keeps wiring tidy in wet or dusty environments.

Flow & Coil Options
| Effective area | 28.0 mm² |
|---|---|
| Flow coefficient | Cv 1.65 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |
| Manual override | Yes (locking / non-locking) |
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.

Where the AirTAC 4V310-10E Solenoid Valve, 5/2-way, PT3/8, AC24V, terminal entry (4V31010E) Is Used
Packaging & Palletising
Drives medium-bore lift and clamp cylinders on case packers and palletisers where spring-return safety is required on E-stop.
Machine Tool Clamping
Controls a double-acting clamp/unclamp circuit on a CNC fixture plate, defaulting to unclamped when the AC24V signal drops.
Test & Assembly Stands
Cycles a press cylinder in a life-cycle test rig; the 4 c/s max frequency handles repetitive duty with filtered shop air.
Is the AirTAC 4V310-10E Solenoid Valve, 5/2-way, PT3/8, AC24V, terminal entry (4V31010E) the Right Valve?
Choose the 4V310-10E when you need a spring-return 5/2 function with an AC24V supply already available in the panel. If your cylinder is smaller (below ~O40 mm) the 4V200 body (Cv 1.0) may be a better energy fit; for bores above ~O80 mm step up to the 4V400 (Cv 2.82). For a valve that holds its last position through a power cycle, the double-solenoid 4V320 series is the alternative. When replacing an existing valve, match all five points: 4V300 body, 5/2 single-solenoid function, 3/8in PT ports, AC24V coil, and terminal-box entry.
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 4V310-10E Solenoid Valve, 5/2-way, PT3/8, AC24V, terminal entry (4V31010E) FAQ
It suits ~O50–80 mm bore cylinders in typical industrial service. The 28.0 mm2 effective area (Cv 1.65) gives ample flow for these sizes without starving the actuator.
No, the ‘E’ suffix denotes an AC24V coil (5.0 VA inrush/holding). For DC24V operation order the 4V310-10B, which uses a 3.0 W DC coil. Always match the coil voltage to your control supply.
