About the AirTAC 4V230C-08F Solenoid Valve, 5/3-way, closed center, PT1/4, DC12V, terminal entry (4V230C08F)
The AirTAC 4V230C-08F is a 5/3-way double-solenoid pneumatic directional valve built on the popular 4V200 mid-body platform. When both solenoids are de-energised, the spool centers and blocks all ports, locking air in the cylinder to hold a double-acting actuator firmly at its mid-stroke position. This closed-center behavior is ideal for applications where the load must not drift when the control signal is removed.
This specific model is configured with a DC12V coil drawing just 2.5 W, making it a good match for mobile or battery-backed control systems. It carries a 1/4-inch PT port size and delivers an effective area of 13.6 mm² (Cv 0.8), suiting double-acting cylinders in the ~Ø32-50 mm range. The aluminum-alloy body weighs 360 g, responds in 0.05 s or less, and is rated IP65 for dusty or wet factory environments.

Where the AirTAC 4V230C-08F Solenoid Valve, 5/3-way, closed center, PT1/4, DC12V, terminal entry (4V230C08F) Is Used
Mid-Stroke Clamping & Holding
Used to stop a double-acting cylinder at an intermediate position for a precise glue-dispensing or pressing operation. The closed center blocks all ports, holding the tooling in place without consuming solenoid power.
Packaging Machine Diverters
Controls a diverter gate on a conveyor line that needs a hard stop in the middle of its stroke. The 4V230C-08F holds the gate steady against product back-pressure when the solenoid is off.
Laboratory Sampling Actuators
Positions a sampling arm at a precise intermediate point in a test sequence. The DC12V 2.5 W coil works safely with low-voltage lab power supplies, and the IP65 rating handles occasional wash-downs.
Is the AirTAC 4V230C-08F Solenoid Valve, 5/3-way, closed center, PT1/4, DC12V, terminal entry (4V230C08F) the Right Valve?
Choose the 4V230C-08F when your pneumatic circuit needs a mid-stroke holding position without continuous solenoid power. The closed center is distinct from the exhaust-center (30E) which lets the cylinder float, or the pressure-center (30P) which pressurises both sides. Ensure the 4V200 body’s 13.6 mm² effective area provides enough speed for your cylinder; for smaller Ø20 mm actuators, the 4V100 series (Cv 0.6) may be more economical, while larger Ø63 mm bores or very fast cycles often benefit from stepping up to the 4V300 series (Cv 1.65).
For a drop-in replacement, match five points: the 4V200 body size, the 5/3 closed-center function (30C), the 1/4-inch PT port, a DC12V coil voltage, and the standard terminal-box electrical entry. This valve can be mounted individually or on a manifold base for multi-valve assemblies.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center

- ✓ 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 4V230C-08F Solenoid Valve, 5/3-way, closed center, PT1/4, DC12V, terminal entry (4V230C08F) FAQ
When both solenoids of the 4V230C-08F lose power, the spool returns to its center position and all ports (P, A, B, EA, EB) are blocked. This traps compressed air on both sides of the cylinder, holding the piston in its current position. Note that this is not a safety brake—for suspended loads, add a pilot-operated check valve or mechanical lock.
Yes, this specific model (4V230C-08F) is built with a DC12V coil rated at 2.5 W, making it directly compatible with 12 VDC battery systems, mobile equipment, and low-voltage control panels. Ensure your power supply can handle the inrush current when the solenoid is first energised.
