About the AirTAC 4V430P-15C Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, terminal entry (4V430P15C)
The AirTAC 4V430P-15C is a 5/3-way double-solenoid valve that directs compressed air to double-acting cylinders and actuators, with a pressure-center spool configuration. When both solenoids are de-energized, the valve shifts to its center position and supplies pressure to both cylinder ports simultaneously, creating a balanced force that resists external movement without fully locking the load.
Built on the large 4V400 aluminum body, this model carries an effective area of 40.0 mm² (Cv 2.35) and suits bore sizes roughly in the Ø80–125 mm range. The 4V430P-15C is configured for AC110V coil power (4.5 VA inrush), uses a terminal box electrical entry, and features PT (Rc) tapered pipe threads on its 1/2-inch ports. Response time is 0.05 seconds or less, and the IP65-rated enclosure ensures reliable operation in dusty or wet plant environments.

Where the AirTAC 4V430P-15C Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, terminal entry (4V430P15C) Is Used
Press & Clamp Retract-Hold
In pneumatic presses where the tool must retract and pause under balanced pressure, the 4V430P-15C pressurizes both sides of the cylinder at center, holding the ram steady against drift without complex external valving.
Tensioning & Back-Pressure Control
Ideal for web-tensioning rollers or material feed systems, the pressure-center spool applies equal force to both cylinder ports at idle, maintaining consistent nip pressure and preventing slack when motion stops.
Large-Bore Gate & Diverter Actuation
For heavy conveyor gates or chute diverters driven by Ø100–125 mm cylinders, this 1/2-inch valve provides the flow capacity (Cv 2.35) to shift large air volumes quickly, while the pressure center holds the gate in a defined mid-stroke position.
Is the AirTAC 4V430P-15C Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, terminal entry (4V430P15C) the Right Valve?
Choose the 4V430P-15C when your double-acting cylinder needs a controlled neutral state where both sides are pressurized—useful for resisting light tooling weight or preventing a sudden drop of pressure upon restart. If your cylinder is smaller (below Ø63 mm), the 4V300 series with a Cv of 1.65 will provide crisper response and save manifold space.
For a correct replacement, match five points: the 4V400 body size, the 5/3 pressure-center function, the 1/2-inch port and PT thread, the AC110V coil voltage, and the terminal box entry. If you need a parallel-thread port, specify the G-thread variant; for a pre-wired flying lead, select the I (grommet) option instead.
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-15C Solenoid Valve, 5/3-way, pressure center, PT1/2, AC110V, terminal entry (4V430P15C) FAQ
In the unactuated center position, the spool connects the supply port to both cylinder ports (A and B) while blocking the exhaust ports. This pressurizes both sides of a double-acting cylinder, creating a balanced force that resists external movement. It is not a safety lock—add a pilot-operated check valve if you need to suspend a load securely.
No. The 4V430P-15C coil is wound specifically for AC110V (4.5 VA). Connecting it to DC voltage will burn the coil immediately. For DC24V operation, order the 4V430P-15B variant, which uses a 3.0 W DC coil and a different armature assembly.
