About the AirTAC 4V430P-15B Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, terminal entry (4V430P15B)
The AirTAC 4V430P-15B is a 5/3-way double-solenoid valve built on the largest 4V body, directing compressed air to double-acting cylinders and actuators with a unique pressure-center function. When both solenoids are de-energized, the spool moves to its center position and applies supply pressure to both cylinder ports simultaneously. This creates a balanced force that can be used to hold a cylinder in a specific mid-stroke position against a consistent opposing load, or to pressurize both sides of a closed system for leak testing.
This DC24V terminal-entry model draws just 3.0 W of coil power and delivers an effective area of 40.0 mm² (Cv 2.35), suiting it for cylinders in the ~Ø80–125 mm range. The aluminum-alloy body weighs 770 g, operates at up to 3 cycles per second, and achieves a response time of 0.05 seconds or less, ensuring crisp, repeatable motion control in demanding pneumatic sequences.

Where the AirTAC 4V430P-15B Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, terminal entry (4V430P15B) Is Used
Balanced Force Clamping
The pressure-center function applies equal pressure to both sides of a clamp cylinder at rest, creating a balanced, vibration-resistant hold on a workpiece without the risk of a spring-back movement.
Leak Test & Pressurization
Ideal for circuits that need to pre-pressurize both sides of a closed system or actuator before a cycle begins, ensuring a consistent starting condition for sensitive test or filling operations.
Large Cylinder Mid-Stroke Hold
Provides a controlled, opposing-force stop for a large-bore cylinder against a constant load, useful in vertical press applications where a simple stop is needed without a full mechanical lock.
Is the AirTAC 4V430P-15B Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, terminal entry (4V430P15B) the Right Valve?
Choose the 4V430P-15B when your application requires a 5/3 pressure-center function on a 1/2-inch ported valve. This center condition is distinct from closed or exhaust centers—use it when you need both sides of a double-acting cylinder to see supply pressure at rest, such as in a clamping application where a balanced force prevents drift or in a circuit that requires a known starting pressure. If your cylinder is smaller (below Ø63 mm), the 4V300 series with its Cv of 1.65 will provide more precise control and faster cycling.
As the largest valve in the 4V family, the 4V400 body is the final step before moving to a larger series or a manifold for higher flow. For a direct replacement, match all five key points: the 4V400 body size, the 5/3 pressure-center function, the 1/2-inch PT thread, a DC24V coil, and the terminal-style electrical entry. This ensures a drop-in fit without modifying your subplate or wiring.

- 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 4V430P-15B Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, terminal entry (4V430P15B) FAQ
In the center position, when neither solenoid is energized, the 4V430P-15B blocks the exhaust ports and connects the supply port to both cylinder ports (A and B). This pressurizes both sides of a double-acting cylinder, creating a balanced force that can hold a position against a steady opposing load or pre-charge a system.
Its 40.0 mm² effective area (Cv 2.35) is well-matched to double-acting cylinders with bore sizes from approximately Ø80 mm to Ø125 mm. It provides sufficient flow for these larger actuators to operate at a responsive speed without being oversized.
