AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15E-AM)
The AirTAC AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15E-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 (4V430E15E-AM)
The 4V430E15E-AM is a 5/3-way double-solenoid directional valve on the 4V400 body, built here with an AC24V coil and standard PT (Rc) tapered 1/2in ports. In the center position both cylinder ports A and B are exhausted, so a double-acting cylinder is vented on both sides and its rod can be moved freely by hand or by an external load. The two coils pulse the spool left or right; when neither coil is energised the spool returns to center and the actuator floats. A mid-position exhaust valve like this suits jog setup, hand-positioning of gates and arms, and any cycle where the actuator must be draggable between strokes.
Flow class is 40.0 mm2 effective area (Cv 2.35) at the 5/3 center, with a maximum cycling rate of 3 cycles per second - enough for cylinders in the roughly O80-125 mm bore range on presses, tilters and large handling arms. Response time is 0.05 s or better, the 770 g aluminum body carries IP65 (DIN40050) protection, and the AC24V coil draws 5.0 VA, a safe low-voltage choice near washdown, outdoor or poorly grounded equipment.

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 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15E-AM) Is Used
Sawmill log-deck alignment arms
O100-125 mm bore rams square logs against the saw line. Cv 2.35 keeps arm cycle time short at 3 c/s, and the exhaust center lets operators nudge a log or arm aside by hand during clears without dumping supply pressure.
Palletizer crate pusher with manual jog
A double-acting O80-100 mm pusher feathering crates onto a pallet benefits from the float mode: at center the pusher slides freely for set-up and jam clearing, while the 0.05 s response keeps the automatic stroke crisp.
Laboratory and test-rig positionable fixture
Test benches with O80-125 mm clamp or tilt cylinders often need the fixture repositionable between runs. The 5/3 exhaust center vents both ports so the rig can be moved by hand, and the AC24V coil suits instrument-room supplies.
Is the AirTAC 4V430E-15 Solenoid Valve, 4V400 Series (4V430E15E-AM) the Right Valve?
Size down before you size up: a cylinder under about O80 mm, or a clamp needing less than roughly 251 kgf push at 0.5 MPa (O80 bore), is better served by the 4V300 body at Cv 1.65 - it is cheaper and seals faster on small volumes. Above O125 mm bore (about 613 kgf push at 0.5 MPa on O125), the 4V400 is the largest valve in the 4V family, so step to a larger valve series or split the circuit across a manifold base instead of over-driving this one. Choose 30E exhaust center only when a free-floating cylinder at mid-position is actually wanted; for a held mid-stroke use 30C, and for both sides under pressure use 30P.
Replacement matching, in order: body size 4V400, function code 30E, port and thread (1/2in, PT - swap to -G for BSPP parallel or -T for NPT), coil voltage (here AC24V, code E), and electrical entry (this SKU is a terminal-box version; an I suffix means a 0.5 m grommet lead). Match all five and the new valve drops straight onto the existing base or plumbing.
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 (4V430E15E-AM) FAQ
5/3-way exhaust center on the 4V400 body: effective area 40.0 mm2 (Cv 2.35), max frequency 3 cycles/sec, response 0.05 s or less, operating pressure 0.15-0.8 MPa (proof 1.2 MPa), air filtered by a 40 um element. This SKU runs an AC24V coil at 5.0 VA with terminal-box entry, IP65 protection, -20 to +70 C, weight 770 g. It suits roughly O80-125 mm double-acting cylinders.
At center both cylinder ports are connected to exhaust, so the piston is unrestrained - the rod floats and can be moved by hand or by the load. That is the point of the 30E function, but it means the valve offers no load holding at all: never rely on it for suspended loads or fall protection. Where a position must be guaranteed, add pilot-operated check valves at the cylinder ports or a mechanical brake alongside the valve.
