About the AirTAC 4V230E-08B Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, terminal entry (4V230E08B)
The 4V230E-08B directs compressed air to double-acting cylinders and actuators with a 5/3-way exhaust-center function. When both solenoids are de-energised, the spool moves to the middle position where cylinder ports A and B are connected to exhaust, allowing the cylinder rod to float freely—ideal for applications where the load must be moved manually or by an external force during a machine stop.
This DC24V model draws just 3.0 W and switches in 0.05 s or less. With an effective area of 13.6 mm² (Cv 0.8) and a maximum cycling rate of 3 cycles per second, it suits ~Ø32–50 mm double-acting cylinders. The aluminium-alloy body weighs 360 g, carries an IP65 protection rating, and requires no lubrication when supplied with 40 µm filtered air.

Where the AirTAC 4V230E-08B Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, terminal entry (4V230E08B) Is Used
Free-Movement Jig Return
On a packaging conveyor, the 4V230E-08B exhausts both sides of a pusher cylinder at the end of the stroke so an operator can slide the jig back by hand without fighting trapped air.
Manual Load-Assist Stations
In an assembly cell, the valve floats a vertical clamp cylinder during part changeover, letting the tooling be repositioned freely before the next automatic cycle locks it in place.
Two-Hand Safety Circuits
Used in a two-hand start circuit where the exhaust-center state guarantees the press cylinder is vented and cannot drift under residual pressure when the operator releases the buttons.
Is the AirTAC 4V230E-08B Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, terminal entry (4V230E08B) the Right Valve?
Choose the 4V230E-08B when your circuit needs the cylinder to go limp at center-off rather than holding position. If you need the piston to lock in place when signals are removed, use the closed-center 4V230C variant instead; if you require both sides pressurised at center, pick the 4V230P. For smaller Ø20–25 mm cylinders the 4V100 series (Cv 0.6) is a better match, while larger Ø63–100 mm bores or faster cycle times call for the 4V300 series (Cv 1.65).
When replacing an existing valve, match five points: body size (4V200), function (5/3 exhaust-center), port and thread (1/4in PT), coil voltage (DC24V), and electrical entry (terminal box). This valve can be mounted singly or ganged on a manifold base, and the manual override lets you test cylinder motion without energising the solenoids.
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-08B Solenoid Valve, 5/3-way, exhaust center, PT1/4, DC24V, terminal entry (4V230E08B) FAQ
Both solenoids de-energise and the spool springs to the center position. In this exhaust-center configuration, ports A and B are vented to atmosphere while the inlet port is blocked. The cylinder rod is free to move, so do not use this valve for load-holding—if the load must stay put, select the closed-center 4V230C or add a pilot-operated check valve at the cylinder ports.
With an effective area of 13.6 mm² (Cv 0.8), it is a good match for double-acting cylinders in the ~Ø32–50 mm range running at typical shop-air pressures of 0.5–0.7 MPa. For smaller Ø20–25 mm cylinders a 4V100-series valve (Cv 0.6) gives finer control, while larger bores or high-speed applications benefit from stepping up to the 4V300 series (Cv 1.65).
