About the AirTAC 4V310-10 Solenoid Valve, 4V300 Series (4V31010FI-W)
The 4V31010FI-W is the external-pilot (-W) build of the AirTAC 4V300-series 5/2 single-solenoid valve. Energise the coil and pressurised air is directed to one side of a double-acting cylinder while the other side exhausts; cut the signal and the spring returns the spool to its rest position, so the valve needs a constant electrical signal to hold the advanced stroke. Because the -W option feeds pilot air through a separate external port rather than tapping it internally from the main line, the spool still shifts dependably on low main-line pressure and in vacuum or low-pressure circuits - a fit internal-pilot valves cannot always make.
This exact SKU pairs the 3/8in PT-tapered body (In/Out 3/8in, exhaust 1/4in) with a DC12V coil drawing 2.5 W and a grommet entry, so it arrives pre-wired with a roughly 0.5 m flying lead - no terminal-box wiring on the machine. Flow capacity sits at an effective area of 28.0 mm2 (Cv 1.65), a class that suits cylinders of roughly O50-80 mm bore. Switching response is 0.05 s or better and the valve weighs 310 g, keeping actuator manifolds light.

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 |

Where the AirTAC 4V310-10 Solenoid Valve, 4V300 Series (4V31010FI-W) Is Used
Low-pressure and vacuum circuits
External pilot supply lets the spool shift even when the main line is at low pressure or under vacuum, where internally piloted 5/2 valves fail to switch.
Larger-bore material handling
Cv 1.65 flow and a 4 cycle/sec rating drive O50-80 mm double-acting cylinders on pushers, lifts and diverters with sub-0.05 s response.
Clamping with fail-safe retraction
Spring return retracts the clamp automatically whenever the DC12V signal drops, and the 12 V 2.5 W grommet coil suits battery- or low-voltage-controlled machines.
Is the AirTAC 4V310-10 Solenoid Valve, 4V300 Series (4V31010FI-W) the Right Valve?
Size first: at Cv 1.65 this body suits ~O50-80 mm bores. Step down to the 4V200 (Cv 1.0) for smaller cylinders or step up to the 4V400 (Cv 2.82) for larger ones. Function-wise, choose this single-solenoid spring-return type when a lost signal must retract the actuator; pick a double-solenoid 5/2 (memory) if the position should persist through power loss, or a 5/3 version when a defined center condition (closed, exhaust or pressure) is required. A single valve suits one actuator; add a manifold base when several valves share one supply. Specify the -W external-pilot variant whenever main-line pressure runs low or the circuit sees vacuum.
For a like-for-like replacement, match all five points: body size 4V300, function 10 (single 5/2 spring return), port and thread (3/8in PT - Rc tapered; G or T/NPT variants exist), coil voltage DC12V, and electrical entry grommet - plus the -W external-pilot suffix.
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 4V310-10 Solenoid Valve, 4V300 Series (4V31010FI-W) FAQ
It is a 5/2 single-solenoid valve for double-acting cylinders and actuators. With an effective area of 28.0 mm2 (Cv 1.65) and a 3/8in PT supply port, it suits bores of roughly O50-80 mm and switches up to 4 cycles per second with a response of 0.05 s or less. It is not rated for single-acting cylinders, which need a 3/2 valve.
The -W suffix means pilot air enters through a dedicated external port instead of being taken from the valve's own inlet, so switching stays reliable when main-line pressure is low or the circuit runs under vacuum. The F grommet coil runs on DC12V at 2.5 W and comes with a pre-wired lead (about 0.5 m), which saves terminal-box wiring on 12 V control systems.
