AirTAC 4V430P-15 Solenoid Valve, 4V400 Series (4V430P15A-AM)
The AirTAC AirTAC 4V430P-15 Solenoid Valve, 4V400 Series (4V430P15A-AM) is a genuine 5/3-way 5/3 double solenoid — pressure center solenoid valve with AM ports and an effective area of 40.0 mm² (Cv 2.35). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.

About the AirTAC 4V430P-15 Solenoid Valve, 4V400 Series (4V430P15A-AM)
Wired straight into a standard AC220V mains control circuit, the 4V430P15A-AM draws only 4.5 VA per coil, so it runs from ordinary factory contactor outputs without a DC power supply. The centre position applies pressure to both sides of a double-acting cylinder at once, balancing the piston against moderate external forces instead of venting it.
Flow is 40.0 mm2 effective area, Cv 2.35, with a 3 cycles-per-second limit, matching cylinders near O80-125 mm bore. This code carries 1/2in PT tapered ports and a terminal box, weighs 770 g, switches in 0.05 s or less, and meets IP65 with a B-class insulation system.

Flow & Coil Options
| Effective area | 40.0 mm² |
|---|---|
| Flow coefficient | Cv 2.35 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |

Where the AirTAC 4V430P-15 Solenoid Valve, 4V400 Series (4V430P15A-AM) Is Used
Plywood hot-press clamp beams
Hot-press clamp rams on O125 mm bores (about 626 kgf push at 0.5 MPa) stay evenly loaded at mid-stroke because the 30P centre pressures both sides; the 4.5 VA AC220V coils tap straight into the plant mains panel.
Lab press platen equalisation
A materials-testing press that must hold its platen level between samples benefits from balanced dual pressure on an O80-100 mm cylinder; with Cv 2.35 and 0.05 s response, re-centring between tests stays crisp.
Canning line lid guide slide
Lid-guide slides fed by O100 mm rams (roughly 400 kgf at 0.5 MPa) resist sideways nudge from passing cans while centred, since pressure centre keeps both chambers live at up to 3 cycles per second.
Is the AirTAC 4V430P-15 Solenoid Valve, 4V400 Series (4V430P15A-AM) the Right Valve?
If your bore sits at O80 mm or below, where push force is about 256 kgf at 0.5 MPa, the 4V300 body at Cv 1.65 usually costs less and switches fast enough. For O100-125 mm bores pushing roughly 400-626 kgf at 0.5 MPa, this is the largest 4V body; beyond that, spec a larger valve series or group several valves on one manifold base.
Pick 30P over 30C when you need a balanced mid-stroke rather than a hard block. Replacements match on five points: 4V400 body, function 30P, 1/2in port with PT thread, AC220V coil, terminal-box entry.
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-15 Solenoid Valve, 4V400 Series (4V430P15A-AM) FAQ
Cv 2.35 with 40.0 mm2 effective area, response 0.05 s or below, maximum frequency 3 cycles per second, operating pressure 0.15-0.8 MPa, proof pressure 1.2 MPa, AC220V coils at 4.5 VA each, 1/2in PT ports, weight 770 g. The 5/2 valves on this same body flow more (48.0 mm2, Cv 2.82), so size stroke speed accordingly.
It holds a cylinder balanced against moderate disturbance because both chambers stay pressurised, but it is not a certified lock. A suspended or overhead load still needs a pilot-operated check valve at the cylinder ports or a mechanical brake; never rely on the centre position alone for fall protection.
