About the AirTAC 4V430C-15F Solenoid Valve, 5/3-way, closed center, PT1/2, DC12V, terminal entry (4V430C15F)
The 4V430C-15F is a 5/3-way double-solenoid pneumatic directional valve built on AirTAC's largest 4V body. When both solenoids are de-energised, the spool centers and blocks all ports—pressure, cylinder A, cylinder B, and both exhausts—so a double-acting cylinder is held firmly in place mid-stroke. This closed-center behavior suits operations where the load must pause without drifting, such as a press that needs to dwell under position control.
This DC12V terminal-box model weighs 770 g and delivers a Cv of 2.35 (effective area 40.0 mm²), comfortably supplying the air volume needed by bore sizes around Ø80–125 mm. The aluminum-alloy body carries an IP65 protection rating, and the spool shifts in 0.05 s or less, giving crisp stopping response even on larger cylinders.

Where the AirTAC 4V430C-15F Solenoid Valve, 5/3-way, closed center, PT1/2, DC12V, terminal entry (4V430C15F) Is Used
Press & Clamp Dwell
Holds a pneumatic press or welding clamp at mid-stroke with all ports blocked, letting the tool dwell under control without air consumption or drift.
Large-Bore Stopper Cylinders
Controls Ø100–125 mm stopper cylinders on heavy pallet conveyors. The closed center keeps the stop raised during a line pause, resisting back-force from the pallet.
Mobile Hydraulic-Pneumatic Jigs
Works on 12 V DC service-vehicle power. The 2.5 W coil and closed-center hold let a truck-mounted alignment jig stay locked in position without draining the battery.
Is the AirTAC 4V430C-15F Solenoid Valve, 5/3-way, closed center, PT1/2, DC12V, terminal entry (4V430C15F) the Right Valve?
Choose the 4V430C-15F when your circuit requires a definite mid-position hold—the closed center locks the cylinder ports so the piston resists external forces during the pause. If you are driving a smaller cylinder (roughly Ø63 mm and below), the 4V300 series with its Cv of 1.65 may offer a more compact, lower-cost fit. For flow beyond what the 4V400 can deliver, step up to a larger valve family or manifold multiple units.
When replacing an existing valve, match five points: body size (4V400), function (5/3 closed-center), port and thread (1/2 inch PT), coil voltage (DC12V), and electrical entry (terminal box). The 2.5 W DC coil runs cool on 12 V mobile or battery-backed systems, making this SKU a practical choice where only low-voltage DC is available.
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 4V430C-15F Solenoid Valve, 5/3-way, closed center, PT1/2, DC12V, terminal entry (4V430C15F) FAQ
With a Cv of 2.35 and effective area of 40.0 mm², it is typically paired with double-acting cylinders in the Ø80–125 mm range. It provides enough flow for rapid stroke on large-bore actuators while the closed center holds the load steady at mid-position.
No. The closed center blocks air from escaping, which resists drift, but it is not a safety-rated holding device. For vertical or suspended loads where a loss of pressure could cause a dangerous drop, you must add a pilot-operated check valve at the cylinder ports or a mechanical brake.
