About the AirTAC 4V330C-10BI Solenoid Valve, 5/3-way, closed center, PT3/8, DC24V, grommet entry (4V330C10BI)
The AirTAC 4V330C-10BI is a 5/3-way double-solenoid pneumatic directional valve that precisely controls double-acting cylinders and actuators. In its de-energized center position, all ports are blocked—this closed-center configuration holds the cylinder firmly in place, making it the go-to choice for applications where drift during a mid-stroke stop is unacceptable. With a 21.3 mm² effective area (Cv 1.25), it suits ~Ø50-80 mm cylinders, and the DC24V coil draws just 3.0 W.
This particular model arrives with a grommet-style electrical entry—a 0.5 m pre-wired flying lead that simplifies DIN-rail wiring and keeps the IP65 protection intact. The spool shifts in 0.05 s or less, and the aluminum-alloy body weighs 450 g. It operates on filtered, non-lubricated air from 0.15-0.8 MPa and can be banked on a manifold base for multi-cylinder systems.

Where the AirTAC 4V330C-10BI Solenoid Valve, 5/3-way, closed center, PT3/8, DC24V, grommet entry (4V330C10BI) Is Used
Clamping & Fixturing
Holds pneumatic clamps at a precise mid-stroke position during machining or welding, preventing part movement when the valve center is closed.
Material Handling Stops
Commands a lift or stop gate to pause mid-travel on a conveyor line, keeping the actuator locked until the next pulse resumes the cycle.
Press & Forming Mid-Cycle Hold
Allows a press cylinder to dwell under position control—the closed center blocks both cylinder ports so the ram doesn't creep during a heating or curing phase.
Is the AirTAC 4V330C-10BI Solenoid Valve, 5/3-way, closed center, PT3/8, DC24V, grommet entry (4V330C10BI) the Right Valve?
Choose the 4V330C-10BI when your double-acting cylinder must lock position at mid-stroke without air consumption holding it—the closed center is purpose-built for that. If your cylinder is smaller (Ø32-40 mm), the 4V200 series (Cv 1.0) may be a better match; for larger bores above 80 mm, step up to the 4V400 (Cv 2.82). This is a double-solenoid valve, so it needs only a momentary pulse to shift and will stay in its last commanded position even if power is lost.
For a drop-in replacement, match five points: body size (4V300), function (5/3 closed-center, code 30C), port and thread (3/8" PT), coil voltage (DC24V), and electrical entry (grommet with flying lead). The grommet entry is especially useful in cabinets where a terminal box would be awkward to reach.
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-10BI Solenoid Valve, 5/3-way, closed center, PT3/8, DC24V, grommet entry (4V330C10BI) FAQ
In the center (de-energized) position, all five ports are blocked. The cylinder ports A and B are sealed, so the piston is held in place by trapped air. This is ideal for mid-stroke stops where you cannot allow the load to drift. Note that for true load-holding safety, a pilot-operated check valve at the cylinder is still recommended.
This specific SKU (4V330C-10BI) is built with a DC24V coil (3.0 W). If your system runs on AC220V or AC110V, you would need the corresponding voltage code—for example, 4V330C-10AI for AC220V with a grommet entry. Always match the coil voltage exactly to avoid burnout or slow shifting.
