About the AirTAC 4V230E-08F Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, terminal entry (4V230E08F)
The AirTAC 4V230E-08F is a 5/3-way double-solenoid pneumatic directional valve built on the proven 4V200 body, configured with a 1/4-inch PT port and a DC12V coil. Its exhaust-center spool design directs compressed air to double-acting cylinders and, when both solenoids are de-energised, connects both cylinder ports to exhaust. This lets the cylinder rod float freely at mid-stroke—ideal for applications where the load must be moved manually or needs zero holding force during a stop phase.
With a 13.6 mm² effective area (Cv 0.8) and a maximum cycling rate of 3 cycles per second, this valve suits ~32–50 mm bore cylinders in moderate-speed sequences. The DC12V coil draws just 2.5 W of power, keeping control-panel heat low. Its aluminum-alloy body weighs 360 g, carries an IP65 protection rating, and includes a locking manual override for direct actuation during setup.

Where the AirTAC 4V230E-08F Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, terminal entry (4V230E08F) Is Used
Manual Load Positioning
In assembly jigs where an operator needs to slide a fixture to a new location by hand between automatic cycles, the exhaust center depressurises the cylinder completely, removing all resistance and enabling smooth, low-effort manual repositioning.
Product Transfer Stops
On a packaging line, a stop gate driven by a double-acting cylinder can be set to float at center. When a jam is cleared, the operator can push the gate open without energising the valve, speeding recovery without overriding the control system.
Clamping with Free Release
In a drilling station, the 4V230E-08F controls a clamp cylinder. At the end of the cycle the exhaust center vents both ports, so the clamp retracts under a light spring or gravity without requiring a powered reverse stroke, simplifying the sequence.
Is the AirTAC 4V230E-08F Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, terminal entry (4V230E08F) the Right Valve?
Choose the 4V230E-08F when your circuit needs a 5/3 exhaust center that depressurises both sides of a double-acting cylinder at neutral, allowing the rod to be moved freely without fighting trapped air. This is a different behavior than the closed-center 4V230C (which blocks all ports to hold position) or the pressure-center 4V230P (which applies pressure to both sides). If your cylinder is smaller than 32 mm bore and cycle speed is not critical, stepping down to the 4V100 series (Cv 0.6) may save space; for bores above 63 mm or faster cycle requirements, move up to the 4V300 body (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 port with PT (Rc) tapered thread, the DC12V coil voltage, and the terminal-box electrical entry. This valve can be mounted individually or ganged on a 4V200 manifold base for multi-station control.

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-08F Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC12V, terminal entry (4V230E08F) FAQ
With a 13.6 mm² effective area (Cv 0.8) and a 3 cycles/sec maximum frequency, this 5/3 valve is well matched to double-acting cylinders in the ~32 mm to 50 mm bore range. It provides adequate flow for general automation tasks; for larger or faster cylinders, the 4V300 series (Cv 1.65) is a better fit.
This is a double-solenoid valve with an exhaust center. When both solenoids are off—whether intentionally or due to a power loss—the spool springs to the center position and both cylinder ports (A and B) are connected to the exhaust ports. The cylinder rod is not held in place; it can be moved freely by an external force. For applications requiring the load to be locked on power loss, use a 5/3 closed-center valve (4V230C) together with a pilot-operated check valve.
