About the AirTAC 4V430E-15BI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, grommet entry (4V430E15BI)
The 4V430E-15BI is a 5/3-way double-solenoid valve from the largest AirTAC 4V series, configured with a DC24V coil and a pre-wired grommet entry for fast DIN-style installation. When both solenoids are de-energised, the exhaust center spool vents both cylinder ports to atmosphere, allowing a double-acting actuator to float freely—ideal for manual positioning or setups where the load must not be held when the machine stops.
With a 40.0 mm² effective area (Cv 2.35) and a 3 cycles/sec maximum frequency, this 770 g aluminum-body valve directs air to bore sizes in the ~Ø80–125 mm range. The DC24V coil draws just 3.0 W, and the spool responds in 0.05 seconds or less, giving crisp, repeatable shifts on large pneumatic cylinders.

Where the AirTAC 4V430E-15BI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, grommet entry (4V430E15BI) Is Used
Manual Load & Unload Stations
The exhaust center lets operators freely move a large pneumatic slide or clamp during part changeover, as both sides of the cylinder are vented to atmosphere when the valve is at rest.
Safety-Interlocked Guards
When a guard opens, de-energising both solenoids instantly dumps air from the cylinder, removing stored energy so the actuator cannot drift under residual pressure.
Large Material Handling
Controls lift-assist or pusher arms on conveyors. The floating center allows the arm to be manually repositioned during jam clearing without fighting trapped air pressure.
Is the AirTAC 4V430E-15BI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, grommet entry (4V430E15BI) the Right Valve?
Choose this exhaust-center model when the application requires the cylinder to be unloaded at rest—common on manual-load stations, safety-interlocked guards, or any process where trapped pressure would be a hazard. If the cylinder must hold position at mid-stroke, select the 4V430C (closed center) instead; if it needs balanced force, the 4V430P (pressure center) is the right call.
This is the 4V400 body, the highest-flow 4V series. For cylinders below ~Ø63 mm, stepping down to a 4V300 (Cv 1.65) often provides a better speed match and a more compact manifold. When replacing an existing valve, confirm all five points: 4V400 body size, 5/3 exhaust-center function, 1/2-inch PT ports, DC24V coil voltage, and the grommet-style electrical entry with its 0.5 m flying lead.
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-15BI Solenoid Valve, 5/3-way, exhaust center, PT1/2, DC24V, grommet entry (4V430E15BI) FAQ
Its 40.0 mm² effective area (Cv 2.35) suits double-acting cylinders roughly in the Ø80–125 mm bore range. For smaller cylinders a 4V300 valve often gives better speed control, while still larger actuators may need a higher-flow valve series or a manifold.
In the center position (both solenoids off), the spool connects both cylinder ports to exhaust. This means the cylinder is not pressurised on either side and can be moved freely by hand. It is a safety feature for applications where the load must not be held when power is removed, but it is not a load-holding brake—add a pilot-operated check valve if vertical load holding is required.
