About the AirTAC 4V430E-15FI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, grommet entry (4V430E15FI)
The AirTAC 4V430E-15FI is a 5/3-way double-solenoid valve on the 4V400 body, configured with a 1/2-inch PT port, a DC12V coil, and a grommet-style electrical entry with a pre-wired 0.5 m flying lead. It directs compressed air to double-acting cylinders and actuators, and its exhaust center function means that when both solenoids are de-energized, the valve spool moves to the middle position where both cylinder ports are connected to exhaust. This allows the attached cylinder to float freely, making it ideal for applications where a load needs to be manually repositioned or where no holding force is required at center.
The 4V400 body provides a 40.0 mm² effective area (Cv 2.35) for 5/3 functions, suiting cylinders in the ~O80-125 mm range. The 2.5 W DC12V coil keeps power consumption low, and the valve achieves a response time of 0.05 seconds or less. With an IP65 protection rating and a robust aluminum-alloy body, it is built for demanding industrial environments.

Where the AirTAC 4V430E-15FI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, grommet entry (4V430E15FI) Is Used
Manual Load Positioning
In assembly stations where a large pneumatic clamp or lift must be freely moved by an operator between cycles, the 5/3 exhaust center allows the double-acting cylinder to float without residual pressure, enabling safe and easy manual repositioning.
Material Handling Gates
Controls large diverter gates on conveyors for O80-125 mm cylinders. The exhaust center permits the gate to be pushed open manually for clearing jams or maintenance without fighting trapped air pressure, enhancing operational safety.
Heavy Part Ejection
Used on a press ejector with a large cylinder, the 4V430E-15FI advances the cylinder to push a formed part out, then centers to exhaust both sides. This lets the ejector plate retract passively via the tool's return springs, simplifying the control circuit and reducing cycle time.
Is the AirTAC 4V430E-15FI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, grommet entry (4V430E15FI) the Right Valve?
Select the 4V430E-15FI when your application requires a large-bore double-acting cylinder to freely float at the center position, a common need in manual load positioning or when a cylinder must not hold pressure when idle. This 4V400 body is the largest in the 4V series; if you are driving a smaller cylinder (~O50-63 mm), stepping down to a 4V300 series valve with a Cv of 1.65 will provide a more appropriately sized and economical solution. For flow requirements exceeding the 4V400's capacity, consider moving to a larger valve series or a manifold assembly.
When replacing an existing valve, match these five points exactly: the 4V400 body size, the 5/3 exhaust center function, the 1/2-inch PT port, a DC12V coil voltage, and a grommet (flying lead) electrical entry. The DC12V grommet configuration is particularly useful in mobile or battery-powered equipment where 12 VDC is the primary control voltage and a simple flying-lead connection is preferred over a terminal box.
Quick checklist

- ✓ 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-15FI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC12V, grommet entry (4V430E15FI) FAQ
With a 40.0 mm² effective area (Cv 2.35), this 4V400 valve is well-matched to double-acting cylinders in the ~O80 to O125 mm bore range. It provides sufficient flow for high-speed cycling of these larger cylinders at the standard 3 cycles/second maximum frequency.
In the de-energized center position, the 5/3 exhaust center spool connects both cylinder ports (A and B) to the exhaust ports, venting all pressure. This causes the cylinder to 'float' freely, allowing the piston rod to be moved by an external force. It is the correct choice when you need to manually position a load or when a tool must not be under pressure during a machine stop, but note that it does not hold a load in place.
