About the AirTAC 4V430E-15B Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, terminal entry (4V430E15B)
This AirTAC 4V430E-15B is a 5/3-way double-solenoid valve built on the largest 4V body, directing compressed air to double-acting cylinders up to roughly 125 mm bore. Its exhaust-center spool vents both cylinder ports to atmosphere when the solenoids are at rest, so the actuator floats freely—ideal for manual positioning or applications where the load must not be locked in place on a stop.
The valve body delivers a 40.0 mm² effective area (Cv 2.35) and operates at up to 3 cycles per second. The DC24V coil draws just 3.0 W, keeping heat low inside the terminal-box enclosure, while the aluminum-alloy spool-and-sleeve assembly responds in 0.05 s or less, giving crisp, repeatable shifts on large-bore pneumatic circuits.

Where the AirTAC 4V430E-15B Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, terminal entry (4V430E15B) Is Used
Manual Jig Adjustment
Operators can float a large clamp cylinder at mid-stroke to reposition tooling by hand. The exhaust center removes air resistance, making manual setup fast and safe.
Two-Position Gluing Stations
A double-acting cylinder pauses in float between two dispense heads, allowing a robot to reposition the part without fighting trapped pressure on either side of the piston.
Pallet Stop & Release
In gravity or low-force conveyors, the valve floats the stop cylinder so a pallet can push it aside. The 4V430E-15B shifts rapidly, keeping pace with high-throughput lines.
Is the AirTAC 4V430E-15B Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, terminal entry (4V430E15B) the Right Valve?
Choose the 4V430E-15B when you need a 1/2-inch 5/3 valve that dumps air at mid-stroke so the cylinder can be moved by hand or by an external force. If your cylinder is smaller—around 63–80 mm bore—the 4V300 series (Cv 1.65) is often a better physical and flow match, reducing manifold footprint. For flows above what the 4V400 can deliver, consider stepping up to a larger body series or ganging valves on a common base.
When replacing an existing valve, match five points: 4V400 body size, 5/3 exhaust-center function, 1/2-inch port with the correct thread (this model is PT/Rc tapered), DC24V coil voltage, and terminal-box electrical entry. Getting all five right ensures the new valve drops onto the same sub-base and connector without rework.
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-15B Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, terminal entry (4V430E15B) FAQ
With a 40.0 mm² effective area (Cv 2.35), this 5/3 valve suits double-acting cylinders in the ~80–125 mm bore range. It provides ample flow for clamping, pressing, and material-handling actuators, while its 3 c/s maximum frequency supports moderate cycling speeds.
In the center position both cylinder ports are connected to exhaust, so the piston is free to move. This is useful for floating or manual positioning but does not hold a load. For vertical or suspended loads, add a pilot-operated check valve or mechanical brake at the cylinder ports—do not rely on the valve alone for load holding.
