About the AirTAC 4V430E-15E Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC24V, terminal entry (4V430E15E)
The AirTAC 4V430E-15E is a 5/3-way double-solenoid valve that directs compressed air to double-acting cylinders, with an exhaust center that vents both cylinder ports to atmosphere when the valve is in its neutral position. This allows the cylinder rod to float freely, making it ideal for applications where the load must be moved manually or where pressure must be completely relieved for safety during a machine stop.
Built on the robust 4V400 aluminum body with 1/2-inch PT ports, this model carries an AC24V coil drawing 5.0 VA and achieves a response time of 0.05 seconds or less. The 5/3 spool provides an effective area of 40.0 mm2 (Cv 2.35), correctly sized for driving larger pneumatic cylinders in the O80 to O125 mm range at a maximum cycling speed of 3 cycles per second.

Where the AirTAC 4V430E-15E Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC24V, terminal entry (4V430E15E) Is Used
Manual Load Positioning
The exhaust center allows a clamped part or heavy fixture to be manually adjusted or removed after the machine cycle stops, as both sides of the cylinder are vented to atmosphere for zero residual pressure.
Press Safety Interlock
In a pneumatic press guarding circuit, this valve's center position instantly dumps downstream air when a safety gate opens, ensuring the press ram cannot drift under trapped pressure and creating a safe state for operator intervention.
Large Part Ejection
Controls a high-force cylinder on a conveyor reject station. The 5/3 exhaust function lets the pusher plate be pushed back by the next product without resistance, simplifying the return stroke and reducing cycle complexity.
Is the AirTAC 4V430E-15E Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC24V, terminal entry (4V430E15E) the Right Valve?
Select the 4V430E-15E when your double-acting cylinder circuit needs a center position that fully dumps air pressure, allowing the actuator to be back-driven or freely positioned. This 5/3 exhaust-center configuration is a direct fit for 1/2-inch PT piping and is the largest body in the 4V series, offering a step up in flow from the 4V300. For smaller cylinders where a Cv of 1.65 is sufficient, the 4V300 body reduces cost and physical size.
When replacing an existing valve, confirm all five key points: the 4V400 body size, the 5/3 exhaust-center function, the 1/2-inch PT thread, an AC24V coil, and the standard terminal box electrical entry. If your application requires holding the cylinder in place at center rather than exhausting, the closed-center 4V430C variant is the correct alternative.
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-15E Solenoid Valve, 5/3-way, exhaust center, PT1/2, AC24V, terminal entry (4V430E15E) FAQ
In the center position, both the cylinder's A and B ports are connected to the exhaust port, venting all pressure. This means the cylinder rod is free to move, which is useful for manual setup, safety interlocks, or allowing an external force to push the actuator back without needing a powered return stroke.
No, the 4V430E-15E is built with an AC24V solenoid coil rated at 5.0 VA. Connecting it to a DC supply will cause the coil to burn out instantly. For a DC24V control system, you need the 4V430E-15B model, which uses a 3.0 W DC coil and provides identical pneumatic performance.
