PRODUCT DESCRIPTION
======================================================================
The Airtac 4V330E-08 is a 5-port 3-position exhaust center solenoid valve designed for precise pneumatic directional control in industrial automation systems. Operating on an internal or external pilot mode, this unit utilizes a sliding column structure engineered to provide good tightness and a sensitive reaction span. Supplied by VD Valve Sdn Bhd in Malaysia, it is built with an aluminum alloy body and features an internal hole processed with specialized technology to minimize friction, reduce starting pressure, and maximize operational service life. The 4V330E-08 requires no added lubrication when integrated into standard pneumatic circuits using air filtered by a 40-micrometre filter element. It accommodates standard coil voltage options including DC24V with IP65 protection and DIN40050 electrical entry. Equipped with an integrated manual override device to facilitate installation and debugging, this model supports panel or manifold mounting configurations suitable for automated machinery, pneumatic actuators, and industrial production lines across Malaysian manufacturing facilities.
