About the AirTAC 4V430P-15FI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, grommet entry (4V430P15FI)
The AirTAC 4V430P-15FI is a 5/3-way double-solenoid valve that directs compressed air to large double-acting cylinders and actuators. In its center position, both cylinder ports are pressurized simultaneously, which can be used to hold a piston rod against a balanced force or to lock a cylinder in a specific orientation during an emergency stop sequence. This specific model is configured with a 0.5 m flying-lead grommet entry and a low-power 2.5 W DC12V coil, making it a good fit for mobile or battery-backed equipment where 24 VDC is not the primary control voltage.
Built on the 4V400 body—the largest in the 4V series—this valve provides an effective area of 40.0 mm2 (Cv 2.35) and suits ~O80-125 mm bore cylinders. The aluminum-alloy body weighs 770 g and the spool responds in 0.05 s or less. With an IP65 protection rating, it handles dusty or washdown environments reliably.

Where the AirTAC 4V430P-15FI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, grommet entry (4V430P15FI) Is Used
Vertical Press Balancing
The pressure-center spool applies equal air to both sides of a large press cylinder at mid-stroke, preventing the tool from drifting downward under gravity when the operator releases the palm buttons.
Tensioning & Clamping Fixtures
In a fixture that clamps a delicate part, the 4V430P-15FI can hold the clamp cylinder with balanced pressure at center, avoiding full clamp force while the part is being aligned or measured.
Lift-Assist on AGVs
A DC12V grommet-lead valve fits neatly into an automated guided vehicle’s low-voltage system, controlling a lift cylinder where the pressure-center position holds the carriage steady during battery-swap or idle periods.
Is the AirTAC 4V430P-15FI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, grommet entry (4V430P15FI) the Right Valve?
Choose the 4V430P-15FI when your double-acting cylinder needs a pressure-center condition—both A and B ports are fed supply pressure at mid-stroke, which can help balance a vertical load during a controlled stop. For smaller cylinders around O63 mm, the 4V300 body (Cv 1.65) is a more economical fit; this 4V400 is the largest 4V body, so for flows beyond Cv 2.35 you would step up to a larger valve series or a manifold. When replacing an existing valve, match all five points: 4V400 body, 5/3 pressure-center function, 1/2-inch PT-threaded ports, a DC12V coil, and the grommet-style electrical entry with its pre-wired 0.5 m lead.
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 4V430P-15FI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC12V, grommet entry (4V430P15FI) FAQ
When both solenoids are de-energized, the spool moves to center and connects both cylinder ports (A and B) to the supply inlet. This pressurizes both sides of the piston, creating a balanced force that resists movement. It is not a safety lock—for suspended loads, add a pilot-operated check valve or mechanical brake.
Yes. The ‘F’ voltage code designates a DC12V coil rated at 2.5 W, and the ‘I’ suffix means it comes with a 0.5 m grommet-style flying lead. This combination is commonly used on mobile machinery, AGVs, and field equipment where 12 VDC is the standard control power.
