About the AirTAC 4V310-10C Solenoid Valve, 5/2-way, PT3/8, AC110V, terminal entry (4V31010C)
The AirTAC 4V310-10C is a 5/2-way single-solenoid pneumatic directional valve engineered to direct compressed air to double-acting cylinders and rotary actuators. Its spool is shifted by energising the AC110V coil and returns via a mechanical spring when the signal is removed, making it ideal 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), this 4V300-series body suits ~O50-80 mm bore cylinders in general industrial automation.
This specific configuration uses a 3/8" PT (Rc) tapered-thread port and a terminal-box electrical entry for hard-wired conduit connections. The AC110V coil draws 4.5 VA and the valve responds in 0.05 seconds or less. The aluminium-alloy body weighs 310 g, operates on filtered, non-lubricated air at 0.15-0.8 MPa, and carries IP65 protection — a robust, fast-acting pilot for clamping, ejecting and diverting tasks.

Where the AirTAC 4V310-10C Solenoid Valve, 5/2-way, PT3/8, AC110V, terminal entry (4V31010C) Is Used
Machine Tool Clamping
Directs a double-acting clamp cylinder on a CNC fixture. Spring return ensures the clamp releases automatically when the AC110V control signal drops, preventing part damage during an E-stop event.
Package Divert Gate
Pilots a mid-range divert cylinder on a packaging conveyor. The 3/8" port and Cv 1.65 flow capacity deliver crisp gate actuation for cartons up to ~O63 mm bore, keeping line rate high.
General Factory Automation
Operates eject, lift and transfer cylinders across assembly stations. The terminal-box entry suits hard-conduit wiring common in fixed machinery, and the AC110V coil integrates with plant control panels.
Is the AirTAC 4V310-10C Solenoid Valve, 5/2-way, PT3/8, AC110V, terminal entry (4V31010C) the Right Valve?
Choose the 4V310-10C when you need a spring-return 5/2 function with an AC110V supply and a 3/8" port that flows Cv 1.65. If your cylinder is smaller (O32-40 mm) and you can accept Cv ~1.0, stepping down to a 4V200-series valve may reduce cost and footprint. For larger bores above O80 mm, the 4V400 body (Cv 2.82) provides the extra flow to maintain cycle speed.
When replacing an existing valve, match five points exactly: body size (4V300), function (single solenoid 5/2), port and thread (3/8" PT), coil voltage (AC110V), and electrical entry (terminal box). This model can be mounted individually or on an AirTAC 300-series manifold base if you are building a multi-station valve group.
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 4V310-10C Solenoid Valve, 5/2-way, PT3/8, AC110V, terminal entry (4V31010C) FAQ
With an effective area of 28.0 mm2 (Cv 1.65), it is a good match for double-acting cylinders in the ~O50-80 mm bore range in typical 0.4-0.7 MPa circuits. The exact speed depends on your supply pressure, tube length and cylinder stroke, but this 4V300 body provides a step up in flow from the smaller 4V200 series.
Yes. As a single-solenoid, spring-return 5/2 valve, the AC110V coil must remain energised to hold the spool in the actuated position. When power is removed, the internal spring pushes the spool back to its normal position, exhausting the previously pressurised cylinder port.
