About the AirTAC 4V320-10EI Solenoid Valve, 5/2-way, PT3/8, AC24V, grommet entry (4V32010EI)
The AirTAC 4V320-10EI is a 5/2-way double-solenoid pneumatic directional valve built on the 4V300 body, directing compressed air to double-acting cylinders and actuators. Its memory function holds the spool in the last pulsed position without constant power—ideal for circuits where the actuator must stay put during an electrical stop or cycle interruption. With a 3/8" PT inlet and outlet and a 1/4" exhaust, it pairs naturally with mid-bore cylinders in the O50-80 mm range.
This particular SKU comes pre-wired with a 0.5 m flying lead through a grommet entry (DIN-style) and an AC24V coil drawing 5.0 VA. The valve delivers an effective area of 28.0 mm² (Cv 1.65) and a response time of 0.05 s or less, all in a 400 g aluminum body rated IP65. It can be mounted singly or ganged on a manifold base for multi-station automation.

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 4V320-10EI Solenoid Valve, 5/2-way, PT3/8, AC24V, grommet entry (4V32010EI) Is Used
Pallet Stop & Transfer
The memory spool keeps a pallet stop raised or lowered during an E-stop cycle, then resumes without re-homing, preventing product pile-ups on conveyor transfers.
Clamp & Hold Fixtures
Pulse the valve to clamp a part, then remove power—the 4V320-10EI holds the clamp position, saving energy and reducing coil heat in long-cycle welding or assembly fixtures.
Press & Forming Tools
Drives a double-acting press cylinder through a full extend-retract cycle. The AC24V grommet coil simplifies wiring into machine-tool control cabinets that use 24 V AC logic.
Is the AirTAC 4V320-10EI Solenoid Valve, 5/2-way, PT3/8, AC24V, grommet entry (4V32010EI) the Right Valve?
Choose the 4V320-10EI when you need a 5/2 double-solenoid valve that retains its last state without holding current. The AC24V grommet version suits control panels that distribute 24 V AC and prefer a pre-wired flying lead over a terminal box. For smaller cylinders (below O50) the 4V200 series (Cv 1.0) is a better match; step up to the 4V400 (Cv 2.82) for bores above O80. When ordering a direct replacement, match all five points: 4V300 body, double-solenoid function (20), 3/8" port, AC24V coil, and grommet electrical entry. The valve also accepts the standard 4V300 manifold base if you plan to expand the station count later.
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 4V320-10EI Solenoid Valve, 5/2-way, PT3/8, AC24V, grommet entry (4V32010EI) FAQ
With an effective area of 28.0 mm² (Cv 1.65), it suits double-acting cylinders roughly in the O50-80 mm bore range at typical operating speeds. The 3/8" supply port and 1/4" exhaust provide a balanced flow path for mid-bore actuators.
The spool stays in its last pulsed position through land friction and balanced pressure, but it is not a safety-rated holding device. If the load must not drift during a pressure loss, add a pilot-operated check valve at the cylinder ports or a mechanical brake—the valve alone does not guarantee load holding.
