About the Airtac 4V200 Solenoid Valve 4V230E-08-A
The AirTAC 4V230E-08A is a 5/3-way double-solenoid pneumatic directional valve that directs compressed air to double-acting cylinders and actuators. Its exhaust-center spool design means that when both solenoids are de-energized, the cylinder ports A and B are connected to exhaust, allowing the actuator to float freely—ideal for applications where the load must be moved manually or by an external force at rest.
Part of the mid-flow 4V200 series, this valve offers an effective area of 13.6 mm² (Cv 0.8) and suits cylinders in the ~Ø32-50 mm range. The AC220V coil draws 4.5 VA, and the valve body weighs 360 g. With a response time of 0.05 s or less and IP65 protection, it delivers reliable performance in demanding industrial environments.

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 |
| Manual override | Yes (locking / non-locking) |
Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Where the Airtac 4V200 Solenoid Valve 4V230E-08-A Is Used
Manual Load/Unload Stations
Operators can freely reposition a cylinder rod at rest because the exhaust center dumps all downstream pressure, removing resistance.
Vertical Gravity-Return Gates
A hopper gate or chute door that drops by its own weight when the valve centers needs both cylinder ports open to atmosphere, which this exhaust-center spool provides.
Clamping with Override
A clamp that must be manually opened for setup benefits from the float condition—no trapped air fights the operator, and the AC220V coil matches common facility power.
Is the Airtac 4V200 Solenoid Valve 4V230E-08-A the Right Valve?
Choose the 4V230E-08A when your application requires a cylinder to go limp at center rest—common in manual-load stations or where a sudden stop must not trap pressure. If you need the cylinder to hold position under pressure loss, step to the closed-center 4V230C variant. For smaller Ø20–25 mm cylinders, the 4V100 series (Cv 0.6) reduces oversizing; for larger bores or faster cycles, the 4V300 (Cv 1.65) provides the needed flow.
When replacing an existing valve, match five points: confirm the 4V200 body size, the 5/3 exhaust-center function, 1/4-inch PT ports, AC220V coil voltage, and terminal-box electrical entry. This valve also mounts on a manifold base for multi-valve assemblies, simplifying piping and reducing potential leak points.
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 4V230E-08-A FAQ
When neither solenoid is energized, both cylinder ports connect to exhaust. The actuator rod can be moved freely by hand or external force because no compressed air is trapped on either side of the piston.
No. The 4V230E-08A coil is wound specifically for 220V AC, 50/60 Hz. Using DC voltage will burn the coil immediately. If your control system outputs 24V DC, order the 4V230E-08B variant instead.
