About the AirTAC 4V430E-15AI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC220V, grommet entry (4V430E15AI)
The 4V430E-15AI is a 5/3-way double solenoid valve built on the largest 4V body, directing compressed air to double-acting cylinders while providing a defined center state. When both solenoids are de-energised, the exhaust center spool vents both cylinder ports to atmosphere, allowing the actuator to float freely—ideal for applications where the load must be moved manually or settle without pneumatic resistance.
This AC220V model comes with a grommet-style electrical entry and a 0.5 m pre-wired flying lead, simplifying installation on DIN rail setups. With an effective area of 40.0 mm² (Cv 2.35) and a maximum cycling rate of 3 cycles per second, it suits bore sizes from approximately Ø80 mm to Ø125 mm. The spool shifts in 0.05 seconds or less, and the aluminum alloy body weighs 770 g, rated for 0.15–0.8 MPa operating pressure with IP65 protection.

Where the AirTAC 4V430E-15AI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC220V, grommet entry (4V430E15AI) Is Used
Large Part Ejection
On a wide-belt conveyor sorting heavy packages, the exhaust center lets a pneumatic pusher retract freely after the blow, preventing trapped pressure that could cause a slow or jerky return stroke.
Manual Load-Assist Fixtures
In a welding cell where an operator positions a heavy clamping arm by hand, the 4V430E-15AI exhausts both sides of the cylinder at neutral, allowing smooth, low-effort manual repositioning without fighting compressed air.
Sawmill Log Stops
Controlling a large stop gate on a log deck, this valve's float-center mode lets the gate drop by gravity when de-energised, while the 1/2-inch ports and Cv 2.35 provide the rapid exhaust needed for high cycle rates.
Is the AirTAC 4V430E-15AI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC220V, grommet entry (4V430E15AI) the Right Valve?
Choose the 4V430E-15AI when your double-acting cylinder needs to coast to a stop or be manually positioned at mid-stroke, as the exhaust center relieves trapped air instantly. If your application instead requires the piston to hold position under a balanced load, step to the closed-center 4V430C variant. For cylinders below Ø63 mm, the smaller 4V300 series (Cv 1.65) typically provides sufficient flow in a lighter, more compact package.
This is the largest body in the 4V family, so if you need still higher flow, consider a larger valve series or a manifold bank. When replacing an existing valve, match all five points: 4V400 body size, 5/3 exhaust-center function, 1/2-inch PT ports, AC220V coil voltage, and the grommet electrical entry with flying lead.
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 4V430E-15AI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC220V, grommet entry (4V430E15AI) FAQ
With an effective area of 40.0 mm² (Cv 2.35), this 4V400-body valve is well-matched to double-acting cylinders in the Ø80 mm to Ø125 mm bore range. For smaller cylinders, a 4V300 series valve may offer better speed control and a more compact footprint.
Both solenoids de-energise and the spool springs to the center position, where the exhaust-center design connects both cylinder ports to the exhaust. This vents all pressure, allowing the piston rod to be moved freely by an external force—it does not lock or hold the load in place.
