AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15A-AM)
The AirTAC AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15A-AM) is a genuine 5/3-way 5/3 double solenoid — exhaust 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 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15A-AM)
Two solenoids shift this 5/3 valve; at center, work ports A and B vent to exhaust while supply is cut, so the cylinder floats and can be nudged by hand or by the load itself. The A suffix fixes an AC220V coil drawing 4.5 VA into a screw-terminal box, and ports are PT 1/2" tapered. Capacity is 40.0 mm2 (Cv 2.35) - lower than the 48.0 mm2 (Cv 2.82) of the 5/2 versions because the center-exhaust spool needs extra land - yet it comfortably drives ~O80-125 mm double-acting cylinders, activating in 0.05 s or less at up to 3 cycles per second.
One design point buyers often miss: because both work ports are open to atmosphere at center, a free piston settles wherever gravity or tooling takes it, so plan your stroke ends or fit flow controls accordingly. The 770 g aluminum body accepts 0.15-0.8 MPa air filtered to 40 um, runs dry without lubrication, and pairs an IP65 class-B coil with a lockable or non-locking override; base mounting builds it into a manifold group.

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 (4V430E15A-AM) Is Used
Jam-clear gate on parcel conveyors
With the valve at center the gate cylinder vents, so line staff can swing the deflector aside by hand during a carton blockage; the AC220V 4.5 VA coil ties straight into standard 220 V control panels.
Weld-cell fixture arms
Positioning arms on O80 mm double-acting cylinders float at center, letting setters align tooling by hand; one pulse to either solenoid then re-takes the pose within 0.05 s.
Case-packer pusher slides
Between batches the pusher cylinder is vented so changeover staff can slide it freely; once re-energised, Cv 2.35 keeps full-speed push strokes on the O100 mm bore at up to 3 cycles per second.
Is the AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15A-AM) the Right Valve?
If your bore is O63 or smaller, the 4V300 body (Cv 1.65) will do the job cheaper; if you later drop the center function entirely, the 5/2 4V420-15 on this same 4V400 body raises flow to Cv 2.82, and anything larger means moving to a bigger series or ganging valves on a manifold. Exhaust center (30E) is the pick when the actuator must drift freely at center; choose 30C to hold position or 30P to keep both sides live.
Ordering a spare? Match five points: 4V400 body, function 30E, 1/2" PT thread, AC220V coil, and terminal-box entry - exactly what this SKU carries.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center

- ✓ 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 (4V430E15A-AM) FAQ
5/3 exhaust center, double solenoid; Cv 2.35 (40.0 mm2 effective area); response 0.05 s or less; max 3 cycles/s; 0.15-0.8 MPa working pressure (1.2 MPa proof); AC220V coil at 4.5 VA; 770 g weight; IP65 (DIN40050), class B insulation; -20 to +70 C; 40 um filtration required.
Closed center (30C) blocks A and B, holding the cylinder frozen; exhaust center (30E, this valve) vents A and B so the actuator drifts with gravity or tooling. Pick 30E for hand-positioning and jam-clearing; if you need guaranteed holding in part of the cycle, add pilot-operated check valves or a mechanical brake rather than relying on the valve alone.
