About the AirTAC 4V310-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V31010F)
The AirTAC 4V310-10F is a 5/2-way single-solenoid directional control valve that directs compressed air to double-acting cylinders and actuators. Its spring-return mechanism demands a constant DC12V electrical signal to hold the shifted position; de-energising the 2.5 W coil instantly returns the spool to its home state, making it a predictable choice for circuits where a defined fail-safe rest position is required.
Built on the 4V300 aluminium body with a 3/8in PT supply port and 1/4in exhaust, this valve provides an effective area of 28.0 mm2 (Cv 1.65) and typically suits ~O50–80 mm bore cylinders. With a response time of 0.05 s or below and IP65 protection, the 4V310-10F delivers fast, reliable cycling for industrial automation tasks.

Where the AirTAC 4V310-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V31010F) Is Used
Packaging & Sorting Lines
Controls double-acting pushers and diverters on conveyor systems. The 4 c/s max frequency and 0.05 s response keep pace with moderate-speed sorting gates and case erectors.
Machine Tool Clamping
Directs air to fixture clamps on CNC mills and drilling stations. The spring-return action ensures clamps release automatically when the DC12V signal is cut, simplifying operator safety logic.
Material Handling Grippers
Powers pneumatic grippers and lift-assist arms. The 28.0 mm2 effective area provides sufficient flow for O63–80 mm bore cylinders that open and close jaws on assembly pallets.
Is the AirTAC 4V310-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V31010F) the Right Valve?
Choose the 4V310-10F when your application needs a single, spring-return 5/2 valve with a DC12V coil and 3/8in PT ports. If you are driving a smaller cylinder (~O32–40 mm), the 4V200 series (Cv 1.0) may be a better flow match; for larger bores above O80 mm, step up to the 4V400 (Cv 2.82). When the valve must hold its last position during a power loss, select the double-solenoid 4V320 instead, or consider a 5/3 closed-center model if you need the cylinder to stop and hold at mid-stroke.
For a direct replacement, match five points: the 4V300 body size, the 5/2 single-solenoid function (10), the 3/8in port with PT thread, the DC12V coil voltage, and the standard terminal-box electrical entry. The valve can be used individually or ganged on a common manifold base for multi-cylinder systems.
Quick checklist

AirTAC 4V310-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V31010F) FAQ
With an effective area of 28.0 mm2 (Cv 1.65), it is typically well-matched to double-acting cylinders in the ~O50–80 mm bore range. Actual speed depends on operating pressure, tubing length, and the load, but the 4 c/s maximum cycling rate gives a good reference for dynamic applications.
The 4V310-10F uses a 2.5 W DC12V coil with a standard terminal-box electrical entry. Ensure your power supply can deliver the inrush current and that wiring conforms to local electrical codes. The coil is IP65-rated, making it suitable for washdown and dusty environments when the terminal box is properly sealed.
