About the AirTAC 4V430P-15AI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC220V, grommet entry (4V430P15AI)
The 4V430P-15AI directs compressed air to double-acting cylinders and actuators, providing a 5/3 pressure-center function. When both solenoids are de-energized, the spool moves to its center position where pressure is applied to both cylinder ports simultaneously, creating a balanced force that resists external movement without a hard mechanical lock.
This AC220V model features a grommet-style electrical entry with a 0.5 m pre-wired flying lead, simplifying installation in DIN-rail environments. The 4V400 body delivers a 40.0 mm2 effective area (Cv 2.35) at up to 3 cycles per second, suiting ~O80-125 mm bore cylinders. The aluminum-alloy body weighs 770 g, and the 4.5 VA coil responds in 0.05 seconds or less, with IP65 protection for demanding industrial settings.

Where the AirTAC 4V430P-15AI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC220V, grommet entry (4V430P15AI) Is Used
Heavy Press Counterbalance
The pressure-center spool keeps both sides of a large pneumatic press cylinder charged at idle, preventing the tooling from sagging under its own weight before the next cycle.
Pallet Lift Assistance
On a large-bore lift cylinder, the 4V430P-15AI applies balanced pressure at center to help counteract a heavy pallet load, reducing the initial burst of air needed to restart motion.
Tensioning & Clamping
Use this valve for roller tensioning on wide web-handling systems. The pressure-center mode maintains a constant, equal force on both sides of the cylinder, keeping the web taut without crushing it.
Is the AirTAC 4V430P-15AI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC220V, grommet entry (4V430P15AI) the Right Valve?
Choose the 4V430P-15AI when your application requires a double-acting cylinder to resist drifting under light external forces at rest—the pressure-center function applies equal pressure to both sides, providing a softer hold than a closed center. For smaller ~O32-63 mm cylinders, step down to the 4V300 series (Cv 1.65) to avoid oversizing. This is the largest 4V body; for still-higher flow, consider a manifolded group or a larger valve series.
When replacing an existing valve, match five points: 4V400 body size, 5/3 pressure-center function, 1/2-inch PT port, AC220V coil voltage, and grommet electrical entry. The pre-wired lead on this model eliminates the need for a separate terminal box connector, speeding up panel wiring.
Quick checklist

AirTAC 4V430P-15AI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC220V, grommet entry (4V430P15AI) FAQ
With a 40.0 mm2 effective area (Cv 2.35) and a 3 cycles/sec max frequency, this 4V400 body valve is typically suited for double-acting cylinders in the ~O80 to O125 mm bore range. It provides ample flow for rapid cycling of large actuators in pressing, lifting, and clamping applications.
When neither solenoid is energized, the spool centers and delivers supply pressure to both cylinder ports (A and B). This creates a balanced force that resists movement. The AC220V coil draws 4.5 VA, and the grommet entry provides a 0.5 m flying lead for direct wiring without a terminal box. Note that for true load-holding safety, a pilot-operated check valve or mechanical brake should be added at the cylinder.
