About the AirTAC 4V230E-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V230E08E)
The AirTAC 4V230E-08E is a 5/3-way double-solenoid pneumatic directional valve with an exhaust center, built on the compact 4V200 aluminum body. When both solenoids are de-energised, the spool shifts to its center position where cylinder ports A and B are connected to exhaust while the inlet is blocked. This allows a double-acting cylinder to float freely, making it ideal for applications where the load needs to be manually repositioned or where pressure must not be trapped during an emergency stop.
With 1/4in PT inlet and outlet ports and a 1/8in PT exhaust, this valve delivers an effective area of 13.6 mm2 (Cv 0.8), suiting pneumatic cylinders in the ~O32-50 mm range. The AC24V coil draws5.0 VA and the spool responds in0.05 seconds or less. The IP65-rated terminal box keeps wiring tidy, and the locking manual override simplifies commissioning.

Where the AirTAC 4V230E-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V230E08E) Is Used
Manual Load-Assist Stations
The exhaust center lets an operator manually push or pull a pneumatic axis into position during setup or after an E-stop, since both sides of the cylinder vent to atmosphere.
Safety-Interlocked Guards
When a safety circuit drops power to both solenoids, the cylinder immediately exhausts, removing stored energy so a guard door or clamp cannot exert force.
Gravity-Fed Chutes
A gate or diverter driven by a double-acting cylinder can be designed to fall to a safe position under gravity when the valve centers and exhausts both ports.
Is the AirTAC 4V230E-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V230E08E) the Right Valve?
Choose the 4V230E-08E when your application needs a double-acting cylinder to go limp at mid-stroke rather than holding position. This is common on manual load-assist stations, doors that must be pushable when power is off, or any axis where trapped air would create a hazard. If you instead need the cylinder to lock in place when the valves are centered, select the closed-center 4V230C-08 variant.
For smaller cylinders around O20-32 mm, the 4V100 series (Cv 0.6) reduces oversizing and saves manifold space. For larger bores above O50 mm or faster cycle rates, step up to the 4V300 body (Cv 1.65). When replacing an existing valve, match all five points: 4V200 body size, 5/3 exhaust-center function, 1/4in PT thread, AC24V coil voltage, and terminal-box 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-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V230E08E) FAQ
In the center position (both solenoids off), the inlet port is closed and both cylinder ports A and B are connected to exhaust. The cylinder is not pressurised on either side, so the piston rod can be moved freely by an external force.
No. The 4V230E-08E has a5.0 VA AC24V coil designed for alternating current only. Connecting it to DC24V will burn out the coil. For a DC24V supply, order the 4V230E-08B variant, which uses a3.0 W DC coil.
