About the AirTAC 4V230C-08C Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, terminal entry (4V230C08C)
The AirTAC 4V230C-08C is a 5/3-way double-solenoid pneumatic directional valve that introduces a precise closed-center position for double-acting cylinders. When both solenoids are de-energized, the spool blocks all ports, trapping air on both sides of the piston to hold the cylinder in place—ideal for applications requiring a mid-stroke stop without drift. This AC110V terminal-box model delivers that hold with a 3.0 W coil and an effective area of 13.6 mm² (Cv 0.8).
Built on the compact 4V200 aluminum body weighing 360 g, this valve suits cylinders in the O32-50 mm range and cycles up to 3 times per second. The spool shifts in 0.05 seconds or less, and the IP65-rated enclosure stands up to washdown and dusty environments. For a genuine AirTAC 5/3 center valve configured for 110 VAC control, this SKU provides a drop-in solution with a locking manual override for setup and troubleshooting.

Where the AirTAC 4V230C-08C Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, terminal entry (4V230C08C) Is Used
Mid-Cycle Clamping
In automated assembly fixtures, the closed center holds a clamp cylinder at a precise intermediate position, allowing an operator or robot to reposition a part without releasing grip pressure.
Stop-and-Hold Gates
Controls a pneumatic gate on a conveyor line that must stop and hold product flow mid-stroke for inspection or diverting, maintaining position even if the emergency stop circuit cuts solenoid power.
Laboratory Positioning
Drives a double-acting actuator on a test fixture that needs to pause at a set point for measurement. The closed center locks the cylinder in place, preventing drift that would skew sensor readings.
Is the AirTAC 4V230C-08C Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, terminal entry (4V230C08C) the Right Valve?
Choose the 4V230C-08C when your double-acting cylinder needs a reliable mid-stroke holding position without continuous power. The closed center blocks all ports at rest, so the load stays put—perfect for pause-and-hold sequences in clamping or pressing. If your cylinder is smaller (below O32 mm), the 4V100 series with Cv 0.6 may offer a more economical match; for larger bores or faster cycling above O50 mm, step up to the 4V300 body (Cv 1.65).
When replacing an existing valve, match five points: the 4V200 body size, the 5/3 closed-center function, the 1/4-inch PT port, a 110 VAC coil, and the terminal-box electrical entry. For multi-valve stations, this body mounts directly onto a 4V200 manifold base, simplifying plumbing and reducing leak points across a bank of valves.
Quick checklist

AirTAC 4V230C-08C Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, terminal entry (4V230C08C) FAQ
In the de-energized center position, all ports (P, A, B, EA, EB) are blocked. This traps compressed air on both sides of a double-acting cylinder piston, holding the load at its current position. It is not a safety lock—use an external pilot-operated check valve if you need guaranteed load holding for suspended weights.
Yes, the 'C' voltage code designates an AC110V 50/60 Hz coil with a 4.5 VA inrush. It connects via the standard terminal box. Ensure your supply is stable within ±10% of rated voltage to prevent coil burnout or sluggish shifting.
