About the AirTAC 4V230E-08BI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, grommet entry (4V230E08BI)
The 4V230E-08BI directs compressed air to double-acting cylinders and actuators with a 5/3-way exhaust-center spool configuration. When both solenoids are de-energized, the center position connects cylinder ports A and B to exhaust, allowing the cylinder to float freely—ideal for applications where the load must be moved manually or the actuator needs to relax without residual pressure. This model comes pre-wired with a 0.5 m flying lead via a grommet entry and operates on a 3.0 W DC24V coil.
Built on the 4V200 aluminum body, it provides an effective area of 13.6 mm2 (Cv 0.8) and suits pneumatic cylinders in the ~O32-50 mm range. The spool shifts in 0.05 seconds or less, and the IP65-rated enclosure keeps dust and low-pressure jets out. A locking manual override is standard, and the valve can be banked on a manifold base for multi-station automation.

|---|---|
| Flow coefficient | Cv 0.8 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |

Where the AirTAC 4V230E-08BI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, grommet entry (4V230E08BI) Is Used
Manual Load Positioning
Operators can freely move a fixture or slide once the valve centers and exhausts both cylinder ports, common on assembly benches with manual changeover.
Relaxed Clamping Stations
Used on end-of-arm tooling where the gripper or clamp must release completely and go limp during a conveyor index to prevent part damage.
Light Assembly Presses
Controls a small press cylinder that needs to retract and float at the end of cycle so the operator can clear the part by hand without fighting back-pressure.
Is the AirTAC 4V230E-08BI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, grommet entry (4V230E08BI) the Right Valve?
Choose this 5/3 exhaust-center valve when the cylinder must go limp at rest for operator safety or manual positioning. If you need the load held in place at mid-stroke, switch to the 4V230C (closed center); for a balanced pressure hold, pick the 4V230P. The 4V200 body sits between the smaller 4V100 (Cv 0.6) and the larger 4V300 (Cv1.65)—this is the right fit for mid-bore cylinders where 0.8 Cv is sufficient. When replacing an existing valve, match five points: 4V200 body size, 5/3 exhaust-center function, 1/4in PT ports, DC24V coil, and the grommet-style electrical entry with flying leads.
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-08BI Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, grommet entry (4V230E08BI) FAQ
In the center position, with neither solenoid energized, both cylinder ports are connected to exhaust. This depressurizes both sides of the piston, allowing the cylinder rod to be moved freely by an external force—ideal for manual setup or safety requirements where stored energy must be released.
Yes, the 4V230E-08BI mounts on any standard 4V200 series manifold base. The grommet wiring exits individually from the top of each valve, so plan your cable routing with the 0.5 m lead length in mind. Ensure the manifold supply pressure is within the 0.15-0.8 MPa range.
