About the AirTAC 4V230E-08AI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC220V, grommet entry (4V230E08AI)
The 4V230E-08AI is a 5/3-way double-solenoid pneumatic directional valve from the AirTAC 4V200 series, configured with an exhaust center. When both solenoids are de-energized, the spool moves to the middle position where both cylinder ports (A and B) are connected to exhaust, allowing a double-acting cylinder to float freely. This model comes with an AC220V coil and a grommet-style electrical entry with a 0.5 m flying lead, simplifying wiring into a DIN-rail cabinet.
With an effective area of 13.6 mm² (Cv 0.8) and a maximum cycling rate of 3 cycles per second, this 360 g aluminum-body valve suits ~Ø32-50 mm double-acting actuators. The spool shifts in 0.05 s or less, and the IP65-rated enclosure protects the 4.5 VA AC coil in dusty or washdown environments.

Where the AirTAC 4V230E-08AI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC220V, grommet entry (4V230E08AI) Is Used
Manual Jog & Setup Stations
Operators can manually move a double-acting cylinder by hand when the valve is de-energized, as the exhaust center dumps all air pressure. Ideal for conveyor diverters that need frequent manual adjustment during product changeovers.
Emergency-Release Clamp Fixtures
In assembly cells, a 5/3 exhaust-center valve ensures that a clamping cylinder immediately releases its grip upon an E-stop, allowing the part to be removed without trapped residual pressure.
Pneumatic Presses with Floating Platen
Used to control a press platen that must float freely during the return stroke or when the machine is idle, preventing any unintended force build-up on tooling or parts.
Is the AirTAC 4V230E-08AI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC220V, grommet entry (4V230E08AI) the Right Valve?
Choose the 4V230E-08AI when your application needs a cylinder to go limp at mid-stroke—common for manual positioning or emergency-release setups where residual pressure must be dumped. The 5/3 exhaust center is the correct choice over a closed center (30C) when you do not want the cylinder to hold position at rest. If your cylinder bore is below Ø25 mm and speed is less critical, the smaller 4V100 body (Cv 0.6) may be a better fit; for bores above Ø63 mm or faster cycling, step up to the 4V300 series (Cv 1.65).
When replacing an existing valve, match five points: the 4V200 body size, the 5/3 exhaust-center function (30E), the 1/4-inch PT port, the AC220V coil voltage, and the grommet (flying-lead) electrical entry. This valve can be used individually or on a manifold base for multi-station pneumatic panels.
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 4V230E-08AI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC220V, grommet entry (4V230E08AI) FAQ
In the center (de-energized) position, both the A and B cylinder ports are connected to the exhaust ports. This means no compressed air is trapped in the cylinder, allowing a double-acting cylinder rod to be moved freely by an external force. It is the opposite of a closed center, which blocks all ports to hold the cylinder in place.
No. The 4V230E-08AI has a 4.5 VA AC220V coil specifically wound for alternating current. Applying DC voltage will not operate the valve correctly and will burn out the coil. For a DC24V version with the same grommet entry, you would need the 4V230E-08BI model.
