About the AirTAC 4V430E-15CI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, grommet entry (4V430E15CI)
The 4V430E-15CI is a 5/3-way double-solenoid pneumatic directional valve that controls double-acting cylinders and actuators with a unique exhaust-center spool arrangement. When both coils are de-energised, the spool springs to the middle position where the cylinder ports A and B are connected to exhaust, allowing the actuator to float freely—ideal for applications where the load must be moved manually or come to rest without trapped air pressure.
This AC110V grommet variant ships with an integrated 0.5 m flying-lead cable for fast DIN-style wiring, drawing 4.5 VA inrush. Built on the largest 4V body, it delivers an effective area of 40.0 mm² (Cv 2.35) and a response time of 0.05 s or less, making it a solid match for driving bore sizes around Ø80–125 mm. The IP65-rated enclosure and anodised aluminium body ensure reliable service in demanding factory conditions.

Where the AirTAC 4V430E-15CI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, grommet entry (4V430E15CI) Is Used
Manual Setup Stations
The exhaust-center spool dumps cylinder pressure at idle, letting operators manually reposition tooling or adjust a clamping jig by hand without fighting trapped air.
Large Press Guarding
Controls a Ø100 mm safety gate cylinder on a forming press. The 4V430E-15CI exhausts both sides when the guard is open, ensuring the platen cannot drift under residual pressure.
Pallet Lift & Transfer
Drives the lift cylinders on a heavy pallet transfer car. The 5/3 exhaust center allows the lift to settle gently onto mechanical stops without an air cushion, simplifying the stop sequence.
Is the AirTAC 4V430E-15CI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, grommet entry (4V430E15CI) the Right Valve?
Select this 4V430E-15CI when your pneumatic circuit requires a 5/3 exhaust-center function on a 1/2-inch ported valve with a pre-wired AC110V connection. The exhaust center is the right call when the cylinder must be depressurised at rest—for instance, when an operator needs to jog a press platen by hand during setup. If your cylinder is smaller (around Ø50–63 mm), stepping down to a 4V300-series valve with a Cv of 1.65 may improve response and reduce air consumption.
For replacement, match five points precisely: the 4V400 body size, the 5/3 exhaust-center function (30E), the 1/2-inch PT-threaded ports, an AC110V coil, and the grommet-style electrical entry. The 4V400 is the highest-flow valve in the 4V family; if you need still greater capacity, consider moving to a larger series or building a manifold bank of 4V400 valves for parallel flow.
Quick checklist

AirTAC 4V430E-15CI Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC110V, grommet entry (4V430E15CI) FAQ
In the center (de-energised) position, both cylinder ports A and B are connected to the exhaust ports. This vents all pressure from the cylinder, allowing the piston rod to be moved freely by an external force—useful for manual setup or when you need the actuator to 'float' at rest.
Yes, the 'C' voltage code designates an AC110V 50/60 Hz coil pulling 4.5 VA. The 'I' suffix means it comes with a grommet-style lead-out and a 0.5 m flying wire, ready to connect directly to a junction box without a separate terminal connector.
