About the AirTAC 4V310-10B Solenoid Valve, 5/2-way, PT3/8, DC24V, terminal entry (4V31010B)
The AirTAC 4V310-10B is a 5/2-way single-solenoid directional valve that directs compressed air to double-acting cylinders and actuators. Its spool is shifted by energising the DC24V coil (3.0 W power draw) and returned by 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.
Built on the 4V300 aluminium-alloy body with a 3/8-inch PT port, this valve provides an effective area of 28.0 mm2 (Cv 1.65) and a maximum cycling rate of 4 cycles per second. It suits double-acting cylinders in the ~O50-80 mm bore range, with a response time of 0.05 seconds or below and IP65-rated protection for the terminal-box electrical entry.

Where the AirTAC 4V310-10B Solenoid Valve, 5/2-way, PT3/8, DC24V, terminal entry (4V31010B) Is Used
Clamping & Fixturing
Drives larger-bore double-acting clamp cylinders on machining centres and welding fixtures. The spring-return action ensures clamps release automatically when the DC24V signal drops, a predictable safety behaviour for load/unload stations.
Material Handling Gates
Controls pneumatic diverters and stop gates on conveyor lines. The 3/8-inch port and Cv 1.65 flow capacity supply enough air to shift O63-80 mm cylinders quickly, keeping sortation cycles under 0.05-second valve response.
Press & Forming Assist
Pilots double-acting cylinders on small pneumatic presses and forming tools. The 4 c/s max frequency supports rapid ram-return sequences, while the DC24V coil simplifies integration with PLC-controlled safety circuits.
Is the AirTAC 4V310-10B Solenoid Valve, 5/2-way, PT3/8, DC24V, terminal entry (4V31010B) the Right Valve?
Choose the 4V310-10B when your double-acting cylinder needs a spring-return 5/2 function with a 3/8-inch port and a DC24V coil. For smaller O32-40 mm cylinders, stepping down to the 4V200 body (Cv 1.0) often reduces cost and space; for bores above O100 mm, the 4V400 (Cv 2.82) provides the higher flow those actuators demand. A single-solenoid valve like this one is the right call when the application requires the spool to return to a safe home position automatically when power is cut.
When replacing an existing valve, match five points: body size (4V300), function (5/2 single solenoid), port and thread (3/8-inch PT), coil voltage (DC24V), and electrical entry (terminal box). The 4V300 series also supports manifold-base mounting, so confirm whether your assembly uses a standalone sub-base or a multi-station manifold before ordering.
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 4V310-10B Solenoid Valve, 5/2-way, PT3/8, DC24V, terminal entry (4V31010B) FAQ
With an effective area of 28.0 mm2 (Cv 1.65), this 4V300-body valve suits double-acting cylinders roughly in the O50-80 mm bore range. Actual speed depends on operating pressure, tubing diameter and cylinder stroke, but the valve's 0.05-second-or-less response time keeps lag to a minimum for most general-automation tasks.
Yes. The 4V310-10B is a single-solenoid, spring-return valve. The DC24V coil must remain energised to hold the spool in the actuated position. When power is removed, the mechanical spring pushes the spool back to its home position, exhausting the previously pressurised cylinder port. This behaviour is intentional for circuits that must fail to a known state.
