About the Airtac 4V400 Solenoid Valve 4V430P-15-A
The AirTAC 4V430P-15A is a 5/3-way double-solenoid valve built on the largest 4V body, directing compressed air to double-acting cylinders and actuators with a 1/2-inch port. Its pressure-center spool applies supply pressure to both cylinder ports when the valve returns to mid-position, which counterbalances the piston and resists external forces—useful when you need to hold a load against a consistent push without drifting.
This AC220V model uses a terminal-box electrical entry and draws 4.5 VA inrush, making it straightforward to wire into standard machine panels. With an effective area of 40.0 mm² (Cv 2.35), a 3 cycles/sec maximum frequency, and a response time of 0.05 s or below, the 4V430P-15A suits ~Ø80–125 mm cylinders in circuits where a centered, pressured state is the safest default.

Where the Airtac 4V400 Solenoid Valve 4V430P-15-A Is Used
Counter-Balanced Press Tools
In a pneumatic press where the tooling must hold position against a constant spring-return force, the 4V430P-15A's pressure center applies equal pressure to both sides of the cylinder at mid-stroke, preventing creep and keeping the tool precisely where it was stopped.
Large-Bore Gate Stops
For a material-handling gate on a conveyor that must resist product weight pushing back when paused, this valve's centered pressure state locks the double-acting cylinder in place with balanced force, so the gate doesn't drift open under load.
Heavy Clamping with Anti-Backdrive
When a clamp on an Ø100 mm cylinder must hold a workpiece against a steady machining force, the pressure-center spool keeps both A and B ports pressurized at rest. This counter-pressure stops the clamp from backing off, even if air supply fluctuates slightly.
Is the Airtac 4V400 Solenoid Valve 4V430P-15-A the Right Valve?
Choose the 4V430P-15A when your double-acting cylinder needs to stop at mid-stroke under balanced pressure—this prevents the rod from being back-driven by a steady opposing force. If your cylinder is smaller (~Ø40–63 mm) and you don't need the pressure-center feature, stepping down to the 4V300 series (Cv 1.65) often saves space and cost. For flow beyond the 4V400's 40.0 mm² effective area, consider a larger valve series or a manifolded group.
When replacing an existing 5/3 pressure-center valve, match five points: body size (4V400), function (30P), port and thread (1/2-inch PT), coil voltage (AC220V), and electrical entry (terminal box). A mismatch on any of these—especially the center condition—will change the actuator's fail-safe behavior, so verify the original part number carefully.
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 4V400 Solenoid Valve 4V430P-15-A FAQ
In the center (de-energised) position, both cylinder ports A and B receive supply pressure simultaneously. This creates a balanced force across the piston, which resists external loads trying to push or pull the rod. It's not a safety lock—if you need guaranteed load holding, add a pilot-operated check valve at the cylinder ports—but it prevents free drifting under a steady opposing force.
With an effective area of 40.0 mm² (Cv 2.35) and a 1/2-inch port, this valve is typically paired with double-acting cylinders in the ~Ø80–125 mm range. The 5/3 body has a slightly smaller flow path than the 5/2 version (48.0 mm²), so factor that in if speed is critical. For smaller cylinders around Ø50–63 mm, a 4V300-series valve is usually a better match.
