About the AirTAC 4V230E-08CI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC110V, grommet entry (4V230E08CI)
This 4V230E-08CI is a 5/3-way pneumatic solenoid valve from the AirTAC 4V200 series, configured with an exhaust center. When both solenoids are de-energized, the spool moves to its middle position, connecting both cylinder ports (A and B) to exhaust while blocking the inlet. This allows a double-acting cylinder to float freely, enabling manual positioning or free movement when air pressure is removed.
Supplied with a pre-wired grommet entry and a 0.5 m flying lead for AC110V operation, this valve simplifies electrical installation in DIN-rail setups. It delivers an effective area of 13.6 mm² (Cv 0.8) and weighs 360 g, making it a solid choice for mid-range automation tasks. The aluminum-alloy body carries an IP65 protection rating and responds in 0.05 seconds or less, ensuring dependable cycle control.

Where the AirTAC 4V230E-08CI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC110V, grommet entry (4V230E08CI) Is Used
Manual Load Assist
In ergonomic lift-assist arms, the exhaust center lets the operator manually reposition the tool when the valve is neutral, providing intuitive, free-floating movement without fighting trapped air pressure.
Diverting Gates
Controls double-acting cylinders on packaging line diverters. The float condition prevents a jammed gate from being force-driven, reducing product damage during a machine halt.
Clamping with Release
Used in assembly fixtures where a clamp must engage for a process step, then fully release both sides to exhaust so the part can be freely removed by a pick-and-place unit.
Is the AirTAC 4V230E-08CI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC110V, grommet entry (4V230E08CI) the Right Valve?
Choose this 5/3 exhaust-center valve when your application requires the actuator to go limp at rest—common in manual load-assist or clamping stations where the tool must be freely movable upon an E-stop. If you need the cylinder to hold position under pressure loss, step to the 4V230C-08 (closed center). For smaller O20-25 mm cylinders, the 4V100 series (Cv 0.6) is a better fit; for larger O63-100 mm bores demanding higher flow, consider the 4V300 series (Cv 1.65).
When replacing an existing valve, match five points: the 4V200 body size, the 5/3 exhaust-center function, the 1/4-inch PT port, the AC110V coil voltage, and the grommet electrical entry. This model can be used as a single unit or mounted on a 4V200 manifold base for grouped valve islands.
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 4V230E-08CI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC110V, grommet entry (4V230E08CI) FAQ
In the unactuated center position, both cylinder ports (A and B) are connected to the exhaust ports while the pressure inlet is blocked. This means a double-acting cylinder connected to the valve will have no trapped pressure and can be moved freely by hand or external forces—a condition often called 'float'.
Yes, the core valve body and pneumatic function are identical. The difference is the electrical entry: this 'I' model comes with a 0.5 m flying lead and a grommet for a DIN-style connector, whereas the standard terminal box uses a PG9 gland. Ensure your wiring plan accommodates the pre-wired lead length.
