About the AirTAC 4V330C-10F Solenoid Valve, 5/3-way, closed center, PT3/8, DC12V, terminal entry (4V330C10F)
The AirTAC 4V330C-10F is a 5/3-way double solenoid 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 firmly in place—ideal for mid-stroke stops where drift is unacceptable. This model operates on a DC12V coil drawing just 2.5 W of power, keeping heat build-up low in continuous-duty applications.
Built on the 4V300 aluminum-alloy body with a PT 3/8" inlet and outlet, this valve delivers an effective area of 21.3 mm² (Cv 1.25) and suits ~Ø50-80 mm bore cylinders. The sliding-spool design responds within 0.05 s and cycles up to 3 times per second. Weighing 450 g, it can be manifold-mounted for multi-valve assemblies and carries an IP65 protection rating for dusty or wet environments.

Where the AirTAC 4V330C-10F Solenoid Valve, 5/3-way, closed center, PT3/8, DC12V, terminal entry (4V330C10F) Is Used
Mid-Stroke Clamping
A 5/3 closed-center valve stops a clamp cylinder partway through its stroke and holds pressure on both sides, preventing the workpiece from shifting during a two-stage machining operation.
Vertical Lift Pause
On a material lift, the 4V330C-10F blocks the cylinder ports at mid-height so a pallet can be inspected or wrapped without drifting downward under gravity.
Press & Forming Tools
A forming press uses the closed center to stop the ram at a precise depth for a dwell period, holding position while another tool engages, then retracting on the next solenoid pulse.
Is the AirTAC 4V330C-10F Solenoid Valve, 5/3-way, closed center, PT3/8, DC12V, terminal entry (4V330C10F) the Right Valve?
Choose the 4V330C-10F when your double-acting cylinder needs a precise mid-stroke holding position without using external pilot checks for short, non-safety-critical pauses. The closed center blocks all flow at rest, so it works best on circuits where the cylinder must not drift under moderate, steady loads. If your application requires a cylinder to float freely at center, select the 30E exhaust-center variant instead.
For smaller ~Ø32-40 mm cylinders, the 4V200 series (Cv 1.0) provides a more economical fit, while larger ~Ø100-125 mm bores demand a 4V400 (Cv 2.82) for adequate speed. When replacing an existing valve, match five points: 4V300 body size, 5/3 closed-center function, 3/8" PT port, DC12V coil voltage, and terminal-style electrical entry. For a grouped installation, order the same valve on a common manifold base to simplify piping and reduce fittings.
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 4V330C-10F Solenoid Valve, 5/3-way, closed center, PT3/8, DC12V, terminal entry (4V330C10F) FAQ
With a Cv of 1.25 and a 21.3 mm² effective area, this valve is well-matched to double-acting cylinders in the ~Ø50-80 mm bore range. It provides adequate fill and exhaust speed for most general automation tasks on that cylinder class without oversizing the valve.
Yes. The DC12V coil consumes only 2.5 W, making it suitable for 12 VDC mobile equipment, vehicle-mounted pneumatics, or any control system where a low-voltage DC supply is standard. Ensure your power supply can handle the inrush current of the solenoid.
