When the valve returns to the center position, the working ports are blocked, helping the cylinder or actuator stop and hold its current position. **Double Solenoid Control** The double solenoid structure allows electrical control in two directions. It is suitable for pneumatic systems that require controlled extension, retraction, and center-position stopping. **3/8 Port for Medium-Flow Pneumatic Systems** With a 3/8″ port size, the 4V330C-10 provides practical airflow capacity for medium pneumatic cylinders, actuators, clamping fixtures, lifting units, and general industrial automation equipment. **Closed Center for Position Holding** The closed center function is useful when an actuator needs to pause during movement. It helps reduce unwanted cylinder movement in the middle position when the pneumatic circuit is properly sealed. **Internal Pilot Operation** The internal pilot structure supports stable valve shifting under normal compressed air pressure. It helps provide responsive switching and reliable air direction control during repeated operation. **Sliding Spool Structure** The sliding spool design provides smooth movement, good sealing performance, and low friction, helping the valve maintain stable operation over long-term use. **Manual Override for Testing** The manual override function helps operators test valve action during installation, commissioning, and maintenance without relying only on electrical control signals. **Ideal Replacement for Airtac 4V300 Series Applications** The 4V330C-10 can be selected for pneumatic systems that require a 4V300 series type 5/3 way closed center double solenoid valve compatible with Airtac 4V300 Series installations. ### Applications The 4V330C-10 solenoid valve is widely used in double-acting cylinder control, pneumatic actuator control, lifting equipment, clamping fixtures, packaging machinery, industrial automation lines, material handling systems, machine tools, and pneumatic control cabinets. It is especially suitable for pneumatic systems that require extend, retract, and center-stop control. The closed center structure helps hold the actuator position when the valve is in the middle state, making it useful for positioning, pausing, and controlled motion applications. ### Why Choose HOMIPNEU HOMIPNEU supplies pneumatic solenoid valves, manual valves, cylinders, fittings, and air source treatment components for industrial automation systems.

The 4V330C-10 is a 5-port, 3-position pneumatic solenoid valve. **What does the “C” mean in 4V330C-10?** The “C” refers to closed center. In the center position, the working ports are blocked to help stop and hold the actuator position. **Is 4V330C-10 a double solenoid valve?** Yes. The 4V330C-10 uses double solenoid control for two-direction electrical switching. **What is the port size of 4V330C-10?** The standard port size is 3/8″, suitable for medium-flow pneumatic cylinder and actuator control systems. **Can 4V330C-10 be used for cylinder positioning?** Yes. The closed center structure can help stop the cylinder in its current position, but actual holding performance also depends on air leakage, cylinder load, seals, and system design. **Is this valve interchangeable with Airtac 4V300 Series?** The 4V330C-10 is designed for 4V300 series type pneumatic valve applications and can be selected for systems using Airtac 4V300 Series style valves. **Does the 4V330C-10 need lubrication?** In clean compressed air systems, additional oil lubrication is generally not required. ### OEM & ODM Support HOMIPNEU provides OEM & ODM support for pneumatic solenoid valves, including voltage options, coil selection, thread options, labeling, packaging, and batch supply for machinery builders, pneumatic distributors, maintenance users, and industrial equipment suppliers.
