About the AirTAC 4V230E-08EI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, grommet entry (4V230E08EI)
The 4V230E-08EI is a 5/3-way double-solenoid pneumatic directional valve built on the mid-flow 4V200 body. When both coils are de-energised, the spool moves to the exhaust center position—both cylinder ports A and B are connected to exhaust while the inlet is blocked. This lets a double-acting cylinder float freely, which is ideal for manual positioning or applications where the actuator must not hold pressure at rest.
This model ships with a pre-wired grommet entry and a 0.5 m flying lead, powered by an AC24V coil drawing 5.0 VA. The 5/3 spool delivers an effective area of 13.6 mm² (Cv 0.8) and a maximum cycling rate of 3 cycles per second, suiting ~Ø32–50 mm double-acting cylinders. Response time is 0.05 s or less, and the IP65-rated aluminium body weighs 360 g.

Where the AirTAC 4V230E-08EI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, grommet entry (4V230E08EI) Is Used
Manual-Assist Clamping
The exhaust center depressurises both cylinder ports at idle, allowing an operator to manually slide a clamp or fixture into position before the next automatic cycle starts.
Free-Rolling Stop Gates
Controls a double-acting gate on a conveyor. When de-energised, the gate floats, letting packages push through gently without pneumatic resistance.
Assembly Station Positioning
Suits assembly jigs where a cylinder must advance under power but be freely movable by hand during part loading and unloading, improving ergonomics and cycle flexibility.
Is the AirTAC 4V230E-08EI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, grommet entry (4V230E08EI) the Right Valve?
Choose the 4V230E-08EI when your circuit requires a 5/3 exhaust-center function on a 1/4" PT port. The exhaust center is the right pick if the cylinder must be depressurised and free to move when the valve is idle—common in manual load-assist or clamping stations where the tool is repositioned by hand. If you need the cylinder to hold position at center, select the closed-center 4V230C instead; for both sides pressurised at center, use the pressure-center 4V230P.
For smaller Ø20–32 mm cylinders, the 4V100 series (Cv 0.6) is a lighter, more compact alternative. For faster cycling or larger Ø50–63 mm bores, step up to the 4V300 body (Cv 1.65). When replacing an existing valve, match five points: 4V200 body size, 5/3 exhaust-center function, 1/4" port with PT thread, AC24V coil voltage, and 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-08EI Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, grommet entry (4V230E08EI) FAQ
In the center (de-energised) position, the inlet port is blocked and both cylinder ports A and B are connected to exhaust. This depressurises both sides of a double-acting cylinder, allowing the piston rod to be moved freely by an external force—often called a 'float' condition.
With an effective area of 13.6 mm² (Cv 0.8) and a 3 cycles/sec max frequency, it is well matched to double-acting cylinders in the ~Ø32–50 mm range. The AC24V coil draws 5.0 VA and the grommet entry provides a 0.5 m pre-wired lead for direct connection without a terminal box.
