About the Airtac 4V200 Solenoid Valve 4V230P-08-A
The AirTAC 4V230P-08A is a 5/3-way double-solenoid pneumatic directional valve with a pressure center spool configuration, designed to direct compressed air to double-acting cylinders and rotary actuators. In its de-energized center position, both cylinder ports (A and B) are pressurized simultaneously, which can be used to apply equal force to both sides of a piston for specific clamping or holding applications where balanced pressure is needed at rest.
This 4V200-series body offers an effective flow area of 13.6 mm² (Cv 0.8) and is suited for driving cylinders in the ~Ø32–50 mm range. The valve operates on a 220V AC coil drawing 4.5 VA, features a sub-0.05-second response time, and weighs 360 g. Its aluminum alloy body carries an IP65 protection rating, and the PT (Rc) tapered thread ports ensure a robust, leak-free pneumatic connection.

Where the Airtac 4V200 Solenoid Valve 4V230P-08-A Is Used
Balanced-Pressure Clamping
Ideal for fixtures where a workpiece must be held with equal, moderate force from both sides of a double-acting cylinder at rest, preventing mechanical drift before the next cycle begins.
Tensioning Mechanisms
Used in web or belt tensioning systems where a constant, balanced air load is needed on the cylinder when the machine is in a neutral state, maintaining consistent material handling.
Mid-Bore Cylinder Control
Directly operates double-acting cylinders in the Ø32–50 mm range for assembly stations and material pushers, where the AC220V terminal-box wiring integrates easily into standard industrial control panels.
Is the Airtac 4V200 Solenoid Valve 4V230P-08-A the Right Valve?
Select the 4V230P-08A when your application requires a 5/3-way valve that pressurizes both cylinder ports at the neutral center position, rather than blocking or exhausting them. This is a specialized function useful for preventing a vertical load from drifting downward by applying counter-pressure, though a dedicated mechanical brake or pilot-operated check valve is mandatory for true load-holding safety. The 1/4-inch supply and outlet ports with 1/8-inch exhausts match the flow needs of mid-sized actuators.
If your cylinder is smaller (below Ø32 mm), stepping down to the 4V100 series (Cv 0.6) can improve energy efficiency and reduce physical size. For larger bores or when faster cycle rates are critical, the 4V300 series (Cv 1.65) provides a higher flow capacity. When replacing an existing valve, verify all five compatibility points: the 4V200 body size, the 5/3 pressure-center function, the 1/4-inch PT port size, the AC220V coil voltage, and the terminal-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 4V200 Solenoid Valve 4V230P-08-A FAQ
In the pressure center configuration, when both solenoids are de-energized, the valve spool shifts to a position that connects the supply port to both cylinder ports (A and B) simultaneously. This applies equal pressure to both sides of a double-acting cylinder piston. It is not a stand-alone safety holding function; a mechanical lock is needed for suspended loads.
The 4V230P-08A has an effective cross-sectional area of 13.6 mm², which corresponds to a Cv factor of 0.8. This flow rate is well-matched to double-acting cylinders with bore sizes approximately between 32 mm and 50 mm. The maximum operating frequency for this 5/3 valve is 3 cycles per second.
