PRODUCT DESCRIPTION
======================================================================
The Airtac 4V330C-10 is a high-performance 5-port 3-position closed center pneumatic solenoid valve designed for precise directional control of air actuators in industrial automation systems. Supplied by VD Valve Sdn Bhd in Malaysia, this direct-acting internal or external pilot-operated valve features a robust aluminum alloy body built in a sliding column mode, ensuring reliable tightness and a sensitive reaction span. The 4V330C-10 model incorporates a 3/8" port size for inlet and outlet connections, with a 1/4" exhaust port, delivering an equivalent orifice Cv value of 1.25. Engineered to operate efficiently within a pressure range of 0.15 to 0.8 MPa (21 to 114 psi) and a proof pressure of 1.2 MPa, it handles filtered air media processed through a 40-micron filter element. The closed center configuration holds pneumatic cylinders securely in position when de-energized. Equipped with standard voltage options such as DC24V and flexible electrical entry choices including terminal and grommet types, this valve integrates seamlessly into automated production lines and manifold assemblies, reducing installation space requirements for industrial applications across Malaysia.
