About the AirTAC 4V320-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V32008E)
The AirTAC 4V320-08E is a 5/2-way double-solenoid pneumatic valve that directs compressed air to double-acting cylinders and rotary actuators. Its memory function means the spool stays locked in the last pulsed position when power is removed—no spring, no holding current—making it ideal for applications where the actuator must remain stationary during an E-stop or power cycle without an immediate return stroke.
Built on the 4V300 aluminum-alloy body, this valve delivers an effective area of 28.0 mm² (Cv 1.65) and suits ~Ø50-80 mm cylinders. The AC24V coil draws 5.0 VA, and the valve responds in 0.05 s or less. With 1/4-inch PT ports, IP65 protection, and a 400 g weight, it is a reliable choice for compact manifold or stand-alone installations.

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 |

Where the AirTAC 4V320-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V32008E) Is Used
Pallet Stop & Gate Control
In powered conveyor systems, the 4V320-08E memory function holds a stop gate or diverter arm in its raised or lowered state during a line stoppage, preventing product drift without continuous coil energization.
Clamp & Fixture Holding
For CNC workholding and welding fixtures, this valve keeps a clamp engaged on the part after the actuation signal is removed. The double-solenoid memory ensures the part stays secured through a power interruption until a deliberate release signal is sent.
Test-Rig Sequencing
Laboratory pneumatic test rigs use the 4V320-08E to sequence multi-step pressure cycles. The memory spool holds intermediate positions between steps, allowing complex test profiles without a PLC continuously energizing every valve station.
Is the AirTAC 4V320-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V32008E) the Right Valve?
Choose the 4V320-08E when your double-acting cylinder needs to hold its working position even if the electrical signal is interrupted—the double-solenoid memory design does exactly that without consuming power in the hold state. If your cylinder is smaller than Ø50 mm, stepping down to a 4V200-series valve (Cv 1.0) often yields a better size-to-flow match; for bores above Ø80 mm, the 4V400 (Cv 2.82) provides the extra flow capacity.
For a drop-in replacement, match five points: the 4V300 body size, the 5/2 double-solenoid function, the 1/4-inch PT port and thread, the AC24V coil voltage, and the terminal-box electrical entry. If you prefer a pre-wired flying lead, the grommet variant (suffix I) eliminates the need to open a terminal box.
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 4V320-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V32008E) FAQ
With an effective area of 28.0 mm² (Cv 1.65), this 4V300-series valve suits double-acting cylinders in the ~Ø50-80 mm range. It can cycle a Ø63 mm bore at its rated 4 cycles-per-second maximum frequency under normal operating pressure.
The double-solenoid memory holds the spool in its last position, but the valve alone is not a safety-rated load-holding device. For vertical or suspended loads where a fall would create a hazard, always add a pilot-operated check valve at the cylinder ports or a mechanical brake—the valve's memory is a control convenience, not a safety brake.
