About the Airtac 4V300 Solenoid Valve 4V310-10-A
The AirTAC 4V310-10A is a 5/2-way single-solenoid directional control valve built on the 4V300 body platform, designed to direct compressed air to double-acting cylinders and rotary actuators. This model is configured with a 3/8-inch PT (Rc) port and an AC220V terminal-box coil drawing 4.5 VA. Energising the solenoid shifts the spool to extend or retract the actuator; de-energising it allows the integrated mechanical spring to return the spool to its home position, making it ideal for circuits where a defined fail-safe rest state is required when power is removed.
With an effective flow area of 28.0 mm² (Cv 1.65) and a maximum cycling rate of 4 cycles per second, the 4V310-10A suits pneumatic systems driving bore sizes in the ~50 to 80 mm range. The sliding-column spool design responds in 0.05 seconds or less, and the IP65-rated aluminium body operates reliably across a 0.15-0.8 MPa pressure band without needing lubricated air.

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 |

Where the Airtac 4V300 Solenoid Valve 4V310-10-A Is Used
Machine Tool Clamping
Controls a double-acting clamp cylinder on a CNC fixture. The spring-return action ensures the clamp releases automatically when AC power is cut, protecting the workpiece and tooling.
Sorting Gate Actuation
Directs a mid-bore pneumatic cylinder that pushes packages onto a divert lane. The 4 c/s max frequency handles rapid sortation cycles, and the AC220V coil integrates easily into factory panel wiring.
Press & Forming Equipment
Pilots a double-acting ram cylinder on a small pneumatic press. The 28.0 mm² effective area provides the flow needed for consistent stroke speed without starving the actuator.
Is the Airtac 4V300 Solenoid Valve 4V310-10-A the Right Valve?
Choose the 4V310-10A when your double-acting cylinder needs a single electrical signal to control a 5/2 circuit with a spring-driven return. The 3/8-inch port and Cv 1.65 flow capacity make it a strong match for mid-bore cylinders; if you are driving a smaller actuator (under ~40 mm bore) where lower flow is acceptable, stepping down to a 4V200-series valve (Cv 1.0) can reduce size and cost. For larger bores above 80 mm that need faster fill, move up to the 4V400 body (Cv 2.82).
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 (AC220V), and electrical entry (terminal box). If your application requires the valve to hold its last position without a constant signal, select the double-solenoid 4V320 variant instead.
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 4V300 Solenoid Valve 4V310-10-A FAQ
With an effective area of 28.0 mm² (Cv 1.65), this 5/2 single-solenoid valve is typically paired with double-acting cylinders in the ~50 to 80 mm bore range. The exact speed depends on operating pressure and tubing size, but the flow capacity is well-matched to mid-size pneumatic actuators.
No—the 4V310-10A coil is rated directly for AC220V 50/60 Hz mains and consumes 4.5 VA. It connects via the standard terminal box, so you can wire it straight into a 220V control circuit without an additional step-down transformer.
