About the AirTAC 4V430E-15F Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, terminal entry (4V430E15F)
The AirTAC 4V430E-15F is a 5/3-way double solenoid valve with an exhaust center, designed to direct compressed air to double-acting cylinders and actuators on larger automation frames. When both solenoids are de-energized, the spool shifts to its center position, immediately connecting both cylinder ports to exhaust. This allows the actuator to 'float' freely, enabling manual positioning or allowing external forces to move the load without air resistance.
Built on the robust 4V400 aluminum body, this model weighs 770 g and provides an effective area of 40.0 mm² (Cv 2.35), making it well-suited for cylinders in the ~Ø80-125 mm range. The DC12V coil draws just 2.5 W of power, offering an energy-efficient solution for mobile or battery-sensitive equipment. Its sliding-column spool design achieves a response time of 0.05 seconds or less, ensuring the exhaust center function engages rapidly when the control signal is removed.

Where the AirTAC 4V430E-15F Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, terminal entry (4V430E15F) Is Used
Large Part Ejectors
On a packaging line, a 4V430E-15F controls a large-bore cylinder that pushes finished boxes off a conveyor. The exhaust center allows the pusher plate to be manually slid back to the home position during a jam clearance, without fighting compressed air.
Clamping with Manual Unload
For a heavy-duty welding fixture, this valve clamps a part with a double-acting cylinder. When the cycle ends, the exhaust center releases all pressure, allowing an operator to freely swing the clamp arm open to remove the finished assembly.
Mobile Hydraulic Alternatives
In a mobile compactor running on a 12V DC system, the 4V430E-15F controls the main ram. The 2.5 W coil is easy on the battery, and the exhaust center lets the ram retract freely by gravity or load force when not powered.
Is the AirTAC 4V430E-15F Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, terminal entry (4V430E15F) the Right Valve?
Select the 4V430E-15F when your pneumatic circuit requires the actuator to go limp at the end of a cycle or during an emergency stop, rather than holding position. This 5/3 exhaust center configuration is a direct fit for the 4V400 body size, the largest in the 4V series, so if your cylinder is smaller than Ø63 mm, stepping down to a 4V300 series valve with its lower Cv of 1.65 will provide more precise flow control. For applications needing even greater flow than this 1/2-inch ported valve can deliver, consider a manifold assembly or moving to a larger body series.
When replacing an existing valve, match these five points exactly: the 4V400 body size, the 5/3 exhaust center function, the 1/2-inch port, the DC12V coil voltage, and the terminal-style electrical entry. The PT (Rc) tapered thread ensures a tight, vibration-resistant seal in the piping.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed

- ✓ 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-15F Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, terminal entry (4V430E15F) FAQ
In the center position, with neither solenoid energized, both the cylinder's A and B ports are connected to the exhaust ports. This means the cylinder is not locked and can be moved freely by hand or external forces, which is ideal for applications requiring manual setup or where the load must not be under pressure at rest.
With an effective area of 40.0 mm² and a Cv of 2.35, the 4V430E-15F is typically paired with double-acting cylinders in the ~Ø80 to 125 mm range. The low 2.5 W power draw from the DC12V coil makes it a strong candidate for systems where minimizing electrical consumption is a priority.
