About the AirTAC 4V430C-15C Solenoid Valve, 5/3-way, closed center, PT1/2, AC110V, terminal entry (4V430C15C)
The 4V430C-15C is a 5/3-way double-solenoid valve built on the largest 4V body, directing air to double-acting cylinders with a closed center position. When both coils are de-energised, all ports are blocked, locking the cylinder in place mid-stroke—ideal for holding a load at an intermediate stop without drifting. This AC110V terminal-box model weighs 770 g and uses a 4.5 VA coil, delivering a response time of 0.05 s or less.
With an effective area of 40.0 mm² (Cv 2.35) and a maximum cycling rate of 3 cycles per second, it suits ~Ø80–125 mm cylinders in clamping, pressing, or positioning tasks. The aluminum-alloy body is IP65-rated and needs no lubrication, operating reliably from 0.15–0.8 MPa with 40 µm filtered air.

Where the AirTAC 4V430C-15C Solenoid Valve, 5/3-way, closed center, PT1/2, AC110V, terminal entry (4V430C15C) Is Used
Heavy Clamping & Fixturing
A closed center holds the clamp force steady when the valve is de-energised, preventing workpiece movement during machining or welding on large-bore cylinders.
Vertical Lift Positioning
Stops a hoist or lift-assist cylinder mid-travel and blocks the ports. Always add a pilot-operated check valve or mechanical brake for suspended-load safety.
Press & Forming Stations
Suits ~Ø100 mm pressing cylinders where the ram must pause under load. The 4V430C holds the pressure balance so the tool stays in place between cycles.
Is the AirTAC 4V430C-15C Solenoid Valve, 5/3-way, closed center, PT1/2, AC110V, terminal entry (4V430C15C) the Right Valve?
Choose this 4V430C-15C when your circuit needs a mid-stroke hold—the closed center blocks cylinder ports so the piston stays put. For smaller ~Ø50–63 mm cylinders, stepping down to a 4V300 series valve (Cv ~1.65) often gives a better size-to-flow match and reduces manifold footprint. Because the 4V400 is the largest body in the 4V family, applications needing still higher flow should look at a larger valve series or a banked manifold arrangement.
When replacing an existing valve, match five points: body size (4V400), function (5/3 closed center), port and thread (1/2 in PT), coil voltage (AC110V), and electrical entry (terminal box). Double-check the center condition—a 4V430E (exhaust) or 4V430P (pressure) will behave differently at neutral, so the ‘C’ in the code is critical for position-hold applications.
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-15C Solenoid Valve, 5/3-way, closed center, PT1/2, AC110V, terminal entry (4V430C15C) FAQ
With a 40.0 mm² effective area (Cv 2.35) it pairs well with double-acting cylinders in the ~Ø80–125 mm range. It is the highest-flow 4V body, so for larger bores consider a bigger valve series; for smaller bores a 4V300 often provides a better match.
When neither solenoid is energised, the spool sits in the center position where pressure, exhaust, and both cylinder ports are all blocked. This traps air on both sides of the piston, holding it in place. The AC110V coil draws 4.5 VA and the terminal-box entry makes wiring straightforward in standard control panels.
