AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15-X0)
The AirTAC AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15-X0) is a genuine 5/3-way 5/3 double solenoid — exhaust center solenoid valve with X0 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 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15-X0)
The 4V430E15-X0 is a double-solenoid 5/3 valve whose centre position exhausts both cylinder ports, so a double-acting cylinder goes slack the instant both coils drop and an operator can re-true the load by hand. Capacity sits in the 4V400 class: 40.0 mm2 effective area, Cv 2.35, and up to 3 cycles per second, which suits cylinders of roughly O80-125 mm bore.
This build uses 1/2in PT tapered ports and a terminal-box electrical entry, weighs 770 g in aluminium alloy, and switches in 0.05 s or less. Air is filtered by a 40 um element, running pressure is 0.15-0.8 MPa, and protection is IP65. No voltage code is written into this suffix, so state the coil voltage you need when you request a quote.

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 |

Where the AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15-X0) Is Used
Weld-table positioner jogging
Welders commonly nudge a heavy rotary positioner between tacks; with Cv 2.35 feeding an O100-125 mm bore, the 30E centre exhausts both ports so the operator can hand-align the seam without fighting trapped air.
Pallet transfer cart stop
Transfer-cart stops on O80 mm cylinders (about 256 kgf push at 0.5 MPa) that should yield if a cart arrives misaligned benefit from the exhaust centre: the ram drifts back under contact instead of dead-blocking it.
Stone-slab vacuum lifter trim
Slab-lifting rigs need a last-inch correction by hand before the vacuum takes the load; the float position lets the O100 mm hook cylinder (roughly 400 kgf at 0.5 MPa) settle freely, while each 0.05 s coil switch keeps trim quick.
Is the AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15-X0) the Right Valve?
Step down to the 4V300 body (Cv 1.65) if your cylinder is below about O80 mm bore and speed at 3 c/s is not the priority. Above O100 mm bore, where push force reaches roughly 400 kgf at 0.5 MPa and O125 reaches about 626 kgf, this 4V400 body is the largest in the 4V family, so still-bigger flow means moving to a larger valve series or building a manifold group on a base.
Choose 30E over 30C when you want the cylinder free at centre, not held. For a drop-in replacement match five points: 4V400 body, function 30E, 1/2in port with PT thread, coil voltage, and 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 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15-X0) FAQ
Effective area 40.0 mm2, Cv 2.35, maximum 3 cycles per second, activating response 0.05 s or below, operating pressure 0.15-0.8 MPa with 1.2 MPa proof pressure. That supports double-acting cylinders of roughly O80-125 mm bore; expect slightly slower stroke speeds than the 5/2 versions of this body, which carry 48.0 mm2 and Cv 2.82.
At centre both A and B ports vent to exhaust, so the cylinder is free to move and can be positioned by hand or gravity. That float is deliberate, not a brake: for a load that must be positively held or lifted overhead, add a pilot-operated check valve at the cylinder ports or a mechanical brake, because this valve alone does not provide fall protection.
