About the AirTAC 4V430E-15C Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, terminal entry (4V430E15C)
The AirTAC 4V430E-15C is a 5/3-way double-solenoid directional control valve built on the largest 4V body, directing compressed air to double-acting cylinders and actuators. Its exhaust center configuration means that when both solenoids are de-energized, the valve spool moves to the middle position, connecting both cylinder ports (A and B) to exhaust while blocking the inlet. This allows the actuator rod to float freely, making it useful for applications where the load must be moved manually or where pressure must be completely released at center for safety during a cycle pause.
This model operates on an AC110V coil drawing 4.5 VA, wired through a standard terminal box. With a 5/3 effective area of 40.0 mm² (Cv 2.35) and a maximum cycling rate of 3 cycles per second, it suits ~Ø80-125 mm bore cylinders. The aluminum-alloy body weighs 770 g, features a response time of 0.05 s or less, and carries an IP65 protection rating, ensuring reliable performance in demanding factory air systems.

Where the AirTAC 4V430E-15C Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, terminal entry (4V430E15C) Is Used
Manual Load Positioning
The exhaust center allows an operator to manually slide a heavy fixture or cylinder rod into place after a cycle pause, as both sides of the piston are vented to atmosphere.
Safety-Interlocked Clamping
In a guarded work cell, de-energizing the valve during a light curtain break instantly exhausts both sides of a clamp cylinder, releasing pressure and allowing the clamp to go slack.
Large Part Ejection
Controls a double-acting pusher on a conveyor line. When the valve centers, the cylinder rod floats, preventing it from being back-driven and damaged if a part jams against it.
Is the AirTAC 4V430E-15C Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, terminal entry (4V430E15C) the Right Valve?
Choose the 4V430E-15C when your pneumatic circuit requires a 1/2-inch, 5/3 valve that safely dumps actuator pressure at the center position. This exhaust-center function is the right call for clamping circuits where you need the jaws to go slack during an emergency stop, or for manual-assist stations where an operator must reposition a cylinder rod by hand. If your cylinder is smaller (under ~Ø63 mm), stepping down to the 4V300 series with its Cv of 1.65 will give you finer control and a more compact manifold footprint.
For replacement, match five points: the 4V400 body size, the 30E function (5/3 exhaust center), the 1/2-inch port in PT thread, the AC110V coil voltage, and the terminal-box electrical entry. This valve is the largest in the 4V family; if you need still higher flow for very large actuators, consider moving to a manifolded group of valves or a larger body series.
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-15C Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, terminal entry (4V430E15C) FAQ
Both solenoids de-energize and the spring-centered spool moves to the middle position. In this exhaust-center valve, both cylinder ports (A and B) are connected to the exhaust ports, dumping all air pressure. The cylinder rod is then free to be moved by external forces, a state often described as 'floating'.
With a Cv of 2.35 and an effective area of 40.0 mm², the 4V430E-15C is well-matched to double-acting cylinders in the ~Ø80 to 125 mm bore range. The AC110V coil provides a 4.5 VA holding power, delivering a strong, reliable shift force on the large spool.
