AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15B-W)
The AirTAC AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15B-W) is a genuine 5/3-way 5/3 double solenoid — exhaust center solenoid valve with W 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 (4V430E15B-W)
Wired around a low-power DC24V coil drawing just 3.0 W, the 4V430E15B-W is the exhaust-center 5/3 variant of the 4V400 body. Its defining behavior is at center: both cylinder ports A and B vent to exhaust, so a double-acting cylinder floats free and can be moved by hand or by an external force while the valve sits idle.
Flow capacity is an effective area of 40.0 mm2 (Cv 2.35) through the 1/2in PT port, with switching in 0.05 s or less and up to 3 cycles per second. At 770 g the valve mounts on individual or manifold bases. The terminal-box entry keeps wiring to a simple screw-terminal connection on the 24 V DC side, and IP65 sealing protects the coil against washdown splash in the Dia80-125 cylinder class it is sized for.

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 |

Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Where the AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15B-W) Is Used
Manual gate on a bottling conveyor
A Dia100 pusher cylinder (about 3927 N at 0.5 MPa) that vents both ports in center, letting line staff slide the gate aside by hand during jam clearing - the DC24V 3.0 W coil suits the 24 V PLC outputs common on filling lines.
Hand-positioned test rig actuator
On an end-of-line leak or fitment tester, the exhaust center lets an operator reposition a Dia80 clamping cylinder between automated cycles, then one pulse re-engages it in under 0.05 s.
Compliant robot gripper arm
A Dia125 gripper close/open cylinder (about 6136 N at 0.5 MPa) that must yield if the part jams; at center both ports exhaust so the tool floats instead of crushing the workpiece.
Is the AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15B-W) the Right Valve?
Compare both neighbours before ordering. The step down is the 4V300 body at Cv 1.65, right for bores up to roughly Dia63 where a Dia80 cylinder (about 2513 N push at 0.5 MPa) would waste valve capacity. The step up leaves the 4V family: the 4V400 is its largest body, so pick a bigger AirTAC series or a manifold arrangement when lines are long or bores exceed Dia125. Pick exhaust center (30E) instead of closed (30C) or pressure (30P) only when a floating actuator is genuinely wanted.
To replace an existing unit without surprises, verify five things: 4V400 body, function 30E, 1/2in port and PT (Rc) thread, DC24V coil (3.0 W), and terminal-box entry - the -I grommet and G/NPT thread versions carry different codes.
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 (4V430E15B-W) FAQ
5/3 exhaust center, double solenoid, 4V400 body: effective area 40.0 mm2 (Cv 2.35), max frequency 3 cycles per second, response 0.05 s or better, working pressure 0.15-0.8 MPa, proof pressure 1.2 MPa, -20 to +70 C, IP65, weight 770 g, 40 um air filtration, lubrication not required. The B coil runs on DC24V at 3.0 W with insulation class B, entered through a terminal box on a 1/2in PT port.
In center the 30E connects both cylinder ports to the exhaust manifold, so the actuator drifts freely under outside force - useful for hand-adjustment and jam relief. A 30C instead blocks both ports and parks the load. Neither center position is a certified holding device; for a load that must never fall, back the valve with pilot-operated check valves or a mechanical brake.
