About the AirTAC 4V230C-08E Solenoid Valve, 5/3-way, closed center, PT1/4, AC24V, terminal entry (4V230C08E)
The AirTAC 4V230C-08E is a 5/3-way double-solenoid valve with a closed center, designed to bring a double-acting cylinder to a controlled stop and hold its position. When both solenoids are de-energized, all ports are blocked, trapping air on both sides of the piston to resist external movement. This 4V200-series body delivers an effective area of 13.6 mm² (Cv 0.8) and suits pneumatic actuators in the ~Ø32-50 mm range.
This model is configured with an AC24V (5.0 VA) coil and a terminal box electrical entry. The valve’s aluminum-alloy body has 1/4-inch PT ports and a sub-0.05-second response time, making it a reliable choice for applications where a mid-stroke pause is required without the cylinder drifting.

Where the AirTAC 4V230C-08E Solenoid Valve, 5/3-way, closed center, PT1/4, AC24V, terminal entry (4V230C08E) Is Used
Mid-Stroke Positioning
Commands a double-acting cylinder to a precise stop and hold, useful for dispensing or inspection stations where the tool must pause without drifting.
Clamping with a Pause
A clamp extends, holds the part securely with blocked ports, and then retracts—ideal for assembly fixtures where the part must not move during a secondary operation.
Two-Stage Pressing
Drives a press to an intermediate position, dwells to allow a material to settle, and then completes the stroke, all controlled by one valve.
Is the AirTAC 4V230C-08E Solenoid Valve, 5/3-way, closed center, PT1/4, AC24V, terminal entry (4V230C08E) the Right Valve?
Choose the 4V230C-08E when your automation sequence needs a cylinder to stop and hold mid-stroke under normal working loads, such as in a two-position gluing station. For smaller Ø20-32 mm cylinders, the 4V100 series (Cv 0.6) offers a more compact package; for larger bores or faster cycles, step up to a 4V300 (Cv 1.65). This 5/3 closed-center function is distinct from the exhaust-center (30E) which lets the cylinder float, and the pressure-center (30P) which applies force to both sides.
When replacing an existing valve, match five points: the 4V200 body size, the 5/3 closed-center function (30C), the 1/4-inch port size, the AC24V coil voltage, and the terminal-box entry style. This valve can be mounted on a manifold base to simplify multi-valve installations.
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 4V230C-08E Solenoid Valve, 5/3-way, closed center, PT1/4, AC24V, terminal entry (4V230C08E) FAQ
When both solenoids are de-energized, the spool moves to the center position, blocking all ports. This traps air in the cylinder, holding the piston in its last commanded position and resisting external forces, provided the system has no leaks.
No. While the closed center resists movement, a pneumatic valve alone is not a safety device for suspended or vertical loads. Air can leak past seals over time, causing drift. Always use a dedicated mechanical brake or a pilot-operated check valve at the cylinder ports for guaranteed load holding.
