About the AirTAC 4V430C-15CI Solenoid Valve, 5/3-way, closed center, PT1/2, AC110V, grommet entry (4V430C15CI)
The 4V430C-15CI is a 5/3-way double-solenoid pneumatic directional valve from the AirTAC 4V400 series, configured for a closed center position. When both solenoids are de-energized, all ports are blocked, holding a double-acting cylinder firmly in place mid-stroke. This model is pre-wired with a 0.5 m flying lead via a DIN-style grommet and operates on an AC110V coil drawing 4.5 VA.
Built on the largest 4V body, it delivers an effective area of 40.0 mm² (Cv 2.35) and can cycle up to 3 times per second. The aluminum-alloy body weighs 770 g and achieves a response time of 0.05 s or less, making it a precise control element for clamping or positioning tasks that require a secure hold at center.

Where the AirTAC 4V430C-15CI Solenoid Valve, 5/3-way, closed center, PT1/2, AC110V, grommet entry (4V430C15CI) Is Used
Heavy-Duty Clamping Fixtures
The closed center holds a clamp cylinder in position with blocked ports, preventing workpiece movement during machining on large fixtures. The AC110V grommet wiring simplifies integration into factory power drops.
Vertical Lift Holding Stations
Used to pause a large-bore lift cylinder mid-stroke for loading or inspection. The valve blocks airflow to hold position, but always pair it with a pilot-operated check valve for suspended load safety.
Pallet Stop & Positioning Gates
Controls a heavy-duty gate cylinder on a conveyor line. The 5/3 closed center locks the gate in place when de-energized, and the 0.05 s response ensures quick cycle times for high-throughput sortation.
Is the AirTAC 4V430C-15CI Solenoid Valve, 5/3-way, closed center, PT1/2, AC110V, grommet entry (4V430C15CI) the Right Valve?
Choose the 4V430C-15CI when your application demands that a double-acting cylinder stops and locks position immediately upon signal loss, without drifting. This closed-center 5/3 configuration is ideal for holding a load at an intermediate point in its stroke. If your cylinder is smaller (O32-O63 mm), stepping down to a 4V300 series valve with a Cv of 1.65 will provide better speed control and energy efficiency.
For replacement, match all five points: the 4V400 body size, the 5/3 closed-center function (30C), the 1/2-inch PT port, an AC110V coil, and the grommet-style electrical entry. If you need a different thread, the same valve is available with G (BSPP) or NPT ports.
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.
