About the AirTAC 4V430P-15F Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, terminal entry (4V430P15F)
The 4V430P-15F is a 5/3-way double-solenoid valve that directs compressed air to large double-acting cylinders, and its pressure-center spool applies supply pressure to both cylinder ports simultaneously when neither solenoid is energized. This balanced-pressure neutral is ideal for applications where you need to counteract external forces or prevent a vertical load from drifting slightly without locking it rigidly—it keeps both sides of the piston under force.
Built on the largest 4V body, this DC12V model draws just 2.5 W of coil power and switches within 0.05 seconds. The 4V400 platform delivers an effective area of 40.0 mm² (Cv 2.35) for 5/3 functions, suiting it to cylinders in the ~Ø80–125 mm range. At 770 g, the aluminum-alloy body includes a manual override and supports manifold assembly.

Where the AirTAC 4V430P-15F Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, terminal entry (4V430P15F) Is Used
Heavy Pressing & Clamping
The pressure-center spool keeps both sides of a large clamping cylinder energized at rest, maintaining grip force on a workpiece without continuous solenoid power.
Balanced Vertical Loads
Counteract the weight of a heavy tooling plate or vertical slide by pressurizing both cylinder ports in the center position, reducing the holding current needed from a servo or brake.
Large-Bore Cylinder Control
Directs air to double-acting cylinders up to Ø125 mm on material-handling gantries and lift-assist devices, where the 40.0 mm² effective area provides the necessary fill rate.
Is the AirTAC 4V430P-15F Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, terminal entry (4V430P15F) the Right Valve?
Choose the 4V430P-15F when your double-acting cylinder needs a controlled neutral state with both sides under pressure—common in pressing or clamping operations where you want to maintain force without energizing a solenoid. For smaller cylinders around Ø50–63 mm, the 4V300 series provides a more appropriately sized Cv of 1.65. Since the 4V400 is the largest body in the 4V family, applications demanding higher flow than its 40.0 mm² effective area should look to a larger valve series or a manifolded group of valves.
This is a double-solenoid 5/3 valve, so it requires two control signals and holds its last commanded position on power loss. When matching a replacement, verify all five points: 4V400 body size, 5/3 pressure-center function, 1/2-inch PT (Rc) tapered thread ports, DC12V coil voltage, and the terminal-box electrical entry.

AirTAC 4V430P-15F Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, terminal entry (4V430P15F) FAQ
In the unactuated center position, both cylinder ports (A and B) are connected to supply pressure. This applies force to both sides of the piston, creating a balanced, pressurized neutral that resists external movement without locking the cylinder.
With an effective area of 40.0 mm² (Cv 2.35) and a 3 cycles/sec max frequency, the 4V430P-15F is typically paired with double-acting cylinders in the ~Ø80–125 mm range on pneumatic systems filtered to 40 µm.
