About the AirTAC 4V230C-06B Solenoid Valve, 5/3-way, closed center, PT1/8, DC24V, terminal entry (4V230C06B)
The 4V230C-06B is a 5/3-way double-solenoid pneumatic directional valve that directs compressed air to double-acting cylinders and actuators with a closed center position. When both solenoids are de-energized, all ports are blocked, trapping air on both sides of the piston to hold the cylinder in place—ideal for mid-stroke stops where drift is unacceptable. This DC24V terminal-box model delivers a 13.6 mm² effective area (Cv 0.8) and suits cylinders roughly Ø32–50 mm.
Built on the aluminum-alloy 4V200 body, the valve weighs 360 g and responds in 0.05 seconds or less. The 3.0 W DC coil runs cool during sustained holding, and the IP65 enclosure with B-class insulation keeps it reliable in dusty or washdown environments. A locking manual override lets you test the circuit without energizing the solenoids.

Where the AirTAC 4V230C-06B Solenoid Valve, 5/3-way, closed center, PT1/8, DC24V, terminal entry (4V230C06B) Is Used
Mid-Stroke Clamping
Holds a pneumatic clamp at an intermediate position for delicate assembly or gluing operations. The closed center prevents the clamp from drifting into the part before the cycle is complete.
Stop-and-Hold Gates
Controls a divert gate on a conveyor line that must pause mid-swing to accumulate product. De-energizing both solenoids locks the gate in place without air consumption.
Test & Measurement Fixtures
Positions a pneumatic slide at a precise inspection height. The 5/3 closed center holds the fixture steady while a vision system or laser sensor takes a measurement.
Is the AirTAC 4V230C-06B Solenoid Valve, 5/3-way, closed center, PT1/8, DC24V, terminal entry (4V230C06B) the Right Valve?
Choose the 4V230C-06B when your application needs a cylinder to stop and hold at mid-stroke without creeping—the closed center blocks all ports so the load stays put. If your cylinder is smaller than Ø32 mm, the 4V100 series (Cv 0.6) may be a better match; for larger bores or faster cycles above Ø50 mm, step up to the 4V300 (Cv 1.65). The 1/8-inch PT ports keep the valve compact for manifold mounting.
When replacing an existing valve, match five points: body size (4V200), function (5/3 closed-center, code 30C), port size and thread (1/8-inch PT), coil voltage (DC24V), and electrical entry (terminal box). This model can be mounted singly or on a common manifold base with other 4V200 valves to build a clean, serviceable valve terminal.
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 4V230C-06B Solenoid Valve, 5/3-way, closed center, PT1/8, DC24V, terminal entry (4V230C06B) FAQ
With a 13.6 mm² effective area (Cv 0.8), it suits double-acting cylinders roughly Ø32–50 mm at typical shop-air pressures. For very small cylinders below Ø25 mm, a 4V100 valve (Cv 0.6) gives finer control; for bores above Ø63 mm or high-speed cycles, consider the 4V300 (Cv 1.65).
No—the closed center blocks the ports but does not create a mechanical lock. If supply pressure drops, trapped air can leak past the spool over time and the load may drift. For suspended or safety-critical loads, add a pilot-operated check valve at the cylinder ports or a dedicated mechanical brake.
