About the AirTAC 4V230E-08FI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, grommet entry (4V230E08FI)
The AirTAC 4V230E-08FI is a 5/3-way double-solenoid pneumatic directional valve built on the mid-flow 4V200 body. Its exhaust-center spool configuration means that when both solenoids are de-energised, the cylinder ports A and B are connected to exhaust while the inlet is blocked. This allows a double-acting cylinder to float freely at center, making it ideal for applications where the load must be manually positioned or where no holding force is required at rest.
This specific model is pre-wired with a 0.5 m flying lead via a grommet entry and operates on a DC12V coil drawing just 2.5 W. The valve has an effective area of 13.6 mm² (Cv 0.8) and a maximum cycling frequency of 3 cycles per second. It weighs 360 g and delivers a response time of 0.05 seconds or less, providing crisp, reliable shifting for mid-bore pneumatic actuators.

Where the AirTAC 4V230E-08FI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, grommet entry (4V230E08FI) Is Used
Manual Load Positioning
The exhaust-center spool depressurises both cylinder ports at idle, allowing an operator to manually slide or reposition a fixture, clamp, or pusher without fighting trapped air pressure.
Assembly Station Actuation
Controls a double-acting cylinder on a small assembly press or staking station. The 2.5 W DC12V grommet coil simplifies wiring into a 12 VDC control system with a pre-wired flying lead.
Diverter & Gate Control
Directs a pneumatic gate or diverter arm on a conveyor line. The float-at-center condition prevents pressure lock, ensuring the gate can be moved freely during a power-off or E-stop event.
Is the AirTAC 4V230E-08FI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, grommet entry (4V230E08FI) the Right Valve?
Choose this 4V230E-08FI when your application requires a double-acting cylinder to be depressurised at both ports in the center position, such as for manual jogging or load-free setups. If you need the cylinder to hold position at center, select the 4V230C (closed center) variant instead. For a simple extend-retract cycle with no mid-stop, a 5/2 single (4V210) or double (4V220) solenoid valve is a more cost-effective choice.
This valve suits ~O32-50 mm bore cylinders. For smaller cylinders (below O25 mm), stepping down to the 4V100 series (Cv 0.6) reduces air consumption. For larger bores or faster cycle times, the 4V300 series (Cv 1.65) provides the extra flow capacity. When replacing an existing valve, match all five points: 4V200 body, 5/3 exhaust-center function, 1/4-inch PT ports, DC12V coil voltage, and the grommet-style electrical entry.
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-08FI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, grommet entry (4V230E08FI) FAQ
With an effective area of 13.6 mm² (Cv 0.8), this 5/3 valve is well-matched to double-acting cylinders in the O32 to O50 mm bore range for typical industrial cycle rates. For smaller O20 mm cylinders, a 4V100 series valve (Cv 0.6) is often a better fit.
This is a 5/3 exhaust-center valve. When both solenoids are de-energised, the valve spool moves to its center position, blocking the pressure port and connecting both cylinder ports to exhaust. The cylinder rod becomes free to move, which is useful for manual setups but means it cannot hold a load against gravity without an external brake.
