About the AirTAC 4V430P-15CI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, grommet entry (4V430P15CI)
The 4V430P-15CI directs compressed air to large double-acting cylinders and actuators with a unique three-position, pressure-center spool. When both solenoids are de-energized, the valve shifts to its center condition where both cylinder ports are simultaneously pressurized, enabling specialized mid-stroke force applications. This 5/3-way configuration uses a double solenoid memory function, meaning the spool holds its last pulsed position without consuming holding current.
Built on the largest 4V body, it delivers an effective area of 40.0 mm² (Cv 2.35) at a maximum cycling rate of 3 cycles per second, suiting pneumatic drives in the Ø80–125 mm range. This specific model is factory-configured for AC110V power via a grommet-style electrical entry with a 0.5-meter flying lead, and its 770-gram aluminum-alloy body achieves a response time of 0.05 seconds or less.

Where the AirTAC 4V430P-15CI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, grommet entry (4V430P15CI) Is Used
Opposed-Force Clamping
Uses the pressure-center position to apply balanced force from both sides of a double-acting cylinder, ideal for delicate part clamping in woodworking or assembly fixtures where a spring return would be too aggressive.
Material Testing Rigs
Controls large-bore actuators in test stands requiring a controlled, pressurized mid-stroke state. The 5/3 pressure-center spool allows a specimen to be pre-loaded from both directions before a test sequence begins.
Heavy Press Counterbalance
Manages the pilot operation of large forming press cylinders. The pressure-center condition can counterbalance a heavy platen, preventing an uncontrolled drop during an emergency stop without needing a full lockout.
Is the AirTAC 4V430P-15CI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, grommet entry (4V430P15CI) the Right Valve?
Select the 4V430P-15CI when your application requires a cylinder to be actively pressured from both sides at rest, such as in a balanced holding or opposed-force clamping setup. As the largest 4V series valve, it is the go-to choice for driving bore sizes from roughly 80 mm up to 125 mm; for smaller cylinders, stepping down to a 4V300 (Cv 1.65) typically provides a better fit and faster cycle times. If your flow demand exceeds the 4V400's capacity, consider moving to a larger valve series or a manifold assembly.
When replacing an existing unit, match five key points: the 4V400 body size, the 5/3 pressure-center function, the 1/2-inch port size, the AC110V coil voltage, and the grommet (flying lead) electrical entry. The PT (Rc) tapered thread on this model ensures a tight, reliable seal in standard piping systems.

AirTAC 4V430P-15CI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, grommet entry (4V430P15CI) FAQ
In its center position (both solenoids off), the valve pressurizes both cylinder ports (A and B) while blocking the exhaust. This applies system pressure to both sides of a double-acting piston, creating a balanced force state. It is distinct from a closed center, which blocks all ports to hold position, or an exhaust center, which vents both ports to let the cylinder float.
Yes, the 'C' voltage code designates an AC110V 50/60 Hz coil drawing 4.5 VA, which is compatible with typical single-phase control power. The 'I' in the code stands for a grommet-style electrical entry, providing a 0.5-meter pre-wired flying lead instead of a terminal box, which can simplify wiring into a tight machine envelope.
