The AirTAC Airtac 4V Solenoid Valves 4V230E-08FIT is a genuine 5/3-way 5/3 double solenoid — exhaust center solenoid valve with 08FIT ports and an effective area of 13.6 mm² (Cv 0.8). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The 4V230E-08FIT is a 5/3-way pneumatic solenoid valve that directs compressed air to double-acting cylinders and actuators, with a center position that exhausts both cylinder ports to atmosphere. When neither solenoid is energized, the spool rests at center and the connected cylinder rod is free to float—ideal for applications where the load must be manually repositioned or where pressure must not be trapped during an emergency stop.
This specific unit is pre-configured with a DC12V coil drawing just 2.5 W of power and a grommet-style electrical entry with a 0.5 m flying lead, making it easy to wire into mobile or battery-powered equipment. The 4V200 body delivers a 13.6 mm² effective area (Cv 0.8) and a maximum cycling speed of 3 cycles per second, with an actuation response time of 0.05 s or less. Its NPT 1/4-inch ports and IP65-rated enclosure suit it for rugged service on assembly stations or packaging machinery.

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.

The exhaust center allows a clamped or positioned cylinder to be freely pushed by hand during changeover or adjustment, speeding up format changes on packaging lines.
In circuits where a guard door must open only after the clamp is fully released, the exhaust center guarantees both sides of the piston are vented, removing stored energy.
The 2.5 W DC12V coil and pre-wired grommet lead suit this valve for lift tables, mobile compactors, and AGV-mounted actuators running from a vehicle battery.
Choose this 4V230E-08FIT when your application needs a double-acting cylinder to go completely limp at center—for instance, when an operator must push a guided slide by hand during setup. The 5/3 exhaust-center function is also commonly used in clamping circuits where both sides of the piston must be depressurized before a safety gate opens. If you instead need to hold the cylinder position at mid-stroke, select the closed-center variant (4V230C); if you need both sides pressurized at center, choose the pressure-center model (4V230P).
For smaller cylinders below about Ø25 mm, stepping down to the 4V100 series (Cv 0.6) can improve response; for larger bores above Ø50 mm or for faster stroke times, the 4V300 (Cv 1.65) provides greater flow. When replacing an existing valve, match all five points: 4V200 body size, 5/3 exhaust-center function, NPT 1/4-inch ports, DC12V coil voltage, and the grommet (flying-lead) electrical entry.
Quick checklist
When both solenoids are off, the spool moves to the center position where both cylinder ports (A and B) are connected to exhaust. This means no compressed air is trapped in the cylinder—the piston rod can be moved freely by an external force. It is the correct choice when you need the actuator to 'float' at rest rather than hold position.
Yes. The 'F' in the part number designates a DC12V coil, which consumes only 2.5 W. The 'I' indicates a grommet entry with a 0.5 m flying wire, so you can connect it directly to a fused 12 V DC supply without needing a separate junction box.
