About the AirTAC 4V230C-08CI Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, grommet entry (4V230C08CI)
The 4V230C-08CI is a 5/3-way pneumatic solenoid valve engineered to stop a double-acting cylinder mid-stroke and hold its position when both solenoids are de-energized. In its closed-center configuration, all five ports are blocked at the neutral position, trapping air on both sides of the piston to resist movement from external forces. This 4V200-series body delivers an effective area of 13.6 mm² (Cv 0.8) and a maximum cycling frequency of 3 cycles per second, suiting it for ~Ø32-50 mm cylinders in clamping and intermediate-stop tasks.
This specific SKU is configured for AC110V control power with a grommet-style electrical entry—a 0.5 m flying lead that simplifies wiring into a DIN connector or terminal strip without a separate junction box. The coil draws 4.5 VA, and the aluminum-alloy valve body weighs 360 g. With a response time of 0.05 s or less and IP65-rated protection, it delivers reliable mid-position control on assembly fixtures and material-handling end-effectors.

Where the AirTAC 4V230C-08CI Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, grommet entry (4V230C08CI) Is Used
Intermediate Clamping Stations
A closed-center 5/3 valve stops a clamp cylinder at a precise mid-position, holding the workpiece without drift while a secondary operation—such as adhesive dispensing or inspection—is performed.
Two-Position Diverter Gates
Controls a double-acting diverter on a packaging conveyor, pausing the gate at a neutral position to accumulate product before committing to the left or right lane.
Assembly Presses with Hold
Drives a press-fit cylinder to an intermediate depth and holds it under blocked-air resistance, allowing an operator to check alignment before the final insertion stroke.
Is the AirTAC 4V230C-08CI Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, grommet entry (4V230C08CI) the Right Valve?
Choose this 5/3 closed-center model when your application requires a cylinder to pause securely at an intermediate point without drifting—common in vertical clamp-and-hold or two-position gluing stations. If your cylinder is smaller than Ø32 mm, stepping down to the 4V100 series (Cv 0.6) reduces oversizing and air consumption. For larger bores or faster stroke speeds above 50 mm, the 4V300 body (Cv 1.65) provides the higher flow needed to maintain cycle time.
When replacing an existing valve, match all five configuration points: the 4V200 body size, the 5/3 closed-center function (30C), the 1/4-inch PT port, the AC110V coil, and the grommet electrical entry. If you are building a multi-valve bank, this manifold-compatible unit drops onto a common base to consolidate supply and exhaust plumbing.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center
- ✓ Coil voltage (DC24 / AC220 …)

- ✓ 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-08CI Solenoid Valve, 5/3-way, closed center, PT1/4, AC110V, grommet entry (4V230C08CI) FAQ
With an effective area of 13.6 mm² (Cv 0.8), this 5/3 valve suits double-acting cylinders in the Ø32-50 mm range for typical industrial cycle rates. Smaller cylinders will operate faster but may be better served by a 4V100-series valve to avoid oversizing.
When both solenoids are de-energized, the spool returns to the spring-centered closed position where all ports are blocked. The air trapped on both sides of the piston resists movement, so the cylinder tends to hold its last position. For suspended or safety-critical loads, always add a pilot-operated check valve or mechanical brake.
