About the Airtac 4V200 Solenoid Valve 4V230C-08-A
The 4V230C-08A is a 5/3-way double-solenoid valve that directs compressed air to double-acting cylinders with a closed center position. When both solenoids are de-energized, all ports are blocked, holding the cylinder at its mid-stroke stop point—ideal for applications where the load must pause without drifting. This AC220V model uses a 4.5 VA coil and connects through a standard terminal box.
Built on the proven 4V200 aluminum body, it delivers an effective area of 13.6 mm² (Cv 0.8) and suits cylinders in the ~Ø32–50 mm range. The sliding-spool design responds in 0.05 s or less, operates at 0.15–0.8 MPa, and carries an IP65 protection rating. Weighing 360 g, it can be used individually or ganged on a manifold base.

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-08-A Is Used
Mid-Stroke Clamping
In assembly fixtures, the closed center holds a clamp cylinder at a precise intermediate position, preventing drift while the operator positions a part.
Stop-and-Hold Gates
On a packaging conveyor, the valve stops a gate cylinder mid-travel to meter product flow, then completes the stroke when the lane clears.
Test Stand Actuation
For a leak-test station, the closed center isolates the cylinder ports, allowing the system to monitor pressure decay without valve cross-bleed.
Is the Airtac 4V200 Solenoid Valve 4V230C-08-A the Right Valve?
Choose the 4V230C-08A when your circuit needs a mid-stroke hold without continuous power. The closed center blocks inlet and exhaust, so the cylinder stops and stays. If your cylinder is smaller (below Ø32), the 4V100 series (Cv 0.6) may be a better match; for larger bores or faster cycling above Ø50, step up to the 4V300 (Cv 1.65).
For a drop-in replacement, match five points: 4V200 body size, 5/3 closed-center function, 1/4-inch PT port, AC220V coil voltage, and terminal-box entry. If your manifold uses BSPP parallel threads, select the G-thread variant; for NPT, choose the T-thread version.
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-08-A FAQ
With an effective area of 13.6 mm² (Cv 0.8), it comfortably drives double-acting cylinders in the ~Ø32–50 mm range at typical shop-air pressures. For a Ø63 mm cylinder, a 4V300-series valve (Cv 1.65) will deliver a faster cycle.
When both solenoids are off, the spool moves to the center position and blocks all ports (P, A, B, EA, EB). The cylinder stops and holds its current position, though for suspended loads a pilot-operated check valve or mechanical brake is required for guaranteed load holding.
