About the AirTAC 4V430P-15EI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC24V, grommet entry (4V430P15EI)
The AirTAC 4V430P-15EI is a 5/3-way double-solenoid valve that applies pressure to both cylinder ports when in its neutral center position. This pressure-center configuration is used to hold a double-acting cylinder against a specific load or to create a balanced force state without fully exhausting either side, useful in clamping applications where you want continuous force applied in both directions. It ships with an AC24V coil drawing 5.0 VA and a grommet-style electrical entry with a 0.5 m pre-wired flying lead for direct DIN-connector-free wiring.
Built on the largest 4V body, this 4V400-series valve provides a 40.0 mm² effective area (Cv 2.35) and a 3 cycles/sec maximum frequency, suiting it to ~O80–125 mm double-acting cylinders. The aluminum-alloy body weighs 770 g, operates from 0.15–0.8 MPa with a 1.2 MPa proof pressure, and achieves a response time of 0.05 s or less. Its IP65-rated enclosure and spool-and-sleeve construction ensure reliable performance in demanding industrial environments.

Where the AirTAC 4V430P-15EI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC24V, grommet entry (4V430P15EI) Is Used
Heavy-Duty Clamping
The pressure-center function keeps both sides of a double-acting clamp cylinder energized at center, maintaining a balanced clamping force on large workpieces in CNC or welding fixtures without drifting.
Press & Forming Control
Controls large-bore ~O100–125 mm cylinders on forming presses, where the 5/3 pressure-center spool applies equal pressure to both ports at neutral, preventing tooling from creeping during dwell phases.
Material Handling Lifts
Suits lift-assist and balancer systems where a double-acting cylinder must maintain a pre-loaded force against a suspended load at mid-stroke, with the AC24V grommet coil simplifying wiring on mobile or gantry equipment.
Is the AirTAC 4V430P-15EI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC24V, grommet entry (4V430P15EI) the Right Valve?
Choose the 4V430P-15EI when your application needs a 5/3 pressure-center valve that actively pressurizes both A and B ports at mid-stroke, rather than blocking or exhausting them. This 4V400 body is the largest in the 4V family; if you are driving a smaller cylinder (~O50–63 mm), stepping down to a 4V300-series valve with its Cv 1.65 may offer a better size-to-flow match. For flows beyond what a single 4V400 can deliver, consider moving to a larger valve series or building a manifold bank.
For a direct replacement, match five points: body size (4V400), function (5/3 pressure-center, code 30P), port and thread (1/2" PT), coil voltage (AC24V), and electrical entry (grommet, code I). The single-solenoid 4V410 offers spring return, while the double-solenoid 4V420 provides a 5/2 memory function. The 5/3 closed-center (30C) and exhaust-center (30E) variants offer different neutral-state behaviors for holding or floating the load.
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-15EI Solenoid Valve, 5/3-way, pressure center, PT1/2, AC24V, grommet entry (4V430P15EI) FAQ
In the de-energized center position, both cylinder ports (A and B) are connected to the supply port (P), pressurizing both sides of a double-acting cylinder simultaneously. This creates a balanced force that can hold a load against a tool or resist external movement, unlike a closed-center valve which blocks all ports or an exhaust-center valve which vents both sides to atmosphere.
With a 40.0 mm² effective area (Cv 2.35) and a 3 cycles/sec maximum frequency, the 4V430P-15EI is typically matched to double-acting cylinders in the ~O80–125 mm range. For smaller cylinders (~O50–63 mm), a 4V300-series valve with Cv 1.65 is often a more proportional choice, while larger or faster cylinders may require a higher-flow valve series.
