About the Airtac 4V200 Solenoid Valve 4V230C-06-A
The AirTAC 4V230C-06A is a 5/3-way double-solenoid valve with a closed center, built on the popular 4V200 aluminum body. When both solenoids are de-energised, all ports are blocked, which locks the connected double-acting cylinder in place at its mid-stroke position—ideal for applications where the load must not drift during an emergency stop or a pause in the cycle.
This model is configured for 1/8-inch PT (Rc) tapered thread ports and operates on a 220 V AC supply, drawing 4.5 VA from the coil. With an effective area of 13.6 mm² (Cv 0.8) and a response time of 0.05 seconds or less, it provides precise, repeatable control for pneumatic actuators in the O32 to O50 mm bore range.

Flow & Coil Options
| Effective area | 13.6 mm² |
|---|---|
| Flow coefficient | Cv 0.8 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |

Where the Airtac 4V200 Solenoid Valve 4V230C-06-A Is Used
Mid-Stroke Holding Stations
Used in assembly fixtures where a cylinder must stop and hold a part precisely at mid-stroke for a secondary operation, with all ports blocked to prevent movement.
Vertical Gate Control
Controls a double-acting cylinder on a vertical gate or diverter, holding the gate in a safe, closed-center position if power is interrupted, preventing it from dropping.
Safety-Interlocked Clamping
In a clamping circuit, the closed center holds clamping force on a workpiece during an E-stop condition, ensuring the part remains secure until the system is reset.
Is the Airtac 4V200 Solenoid Valve 4V230C-06-A the Right Valve?
Choose the 4V230C-06A when your circuit requires a 5/3 closed-center function on a 1/8-inch ported base. This valve is a step up in flow from the 4V100 series (Cv 0.6) and is correctly sized for mid-range double-acting cylinders. If your application demands higher flow for larger bores or faster cycle rates, consider moving to the 4V300 body with a Cv of 1.65.
For direct replacement, match all five points: the 4V200 body size, the 5/3 closed-center function, the 1/8-inch PT port, the AC220V terminal-box coil, and the terminal-style electrical entry. This valve can be used as a single unit or ganged on a manifold base for multi-cylinder control panels.
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 4V200 Solenoid Valve 4V230C-06-A FAQ
With a Cv of 0.8 and an effective area of 13.6 mm², this 5/3 valve is well-matched to double-acting cylinders from approximately 32 mm to 50 mm bore. For smaller O20 mm cylinders, a 4V100 series valve (Cv 0.6) may be more economical.
The 4V230C-06A has a closed center, meaning all air paths are blocked at the spool's center position. When both solenoids are de-energised, the air is trapped in the cylinder, holding the piston and load in place. Note that this is not a safety-rated holding brake; for suspended loads, an additional mechanical brake or pilot-operated check valve is required.
