PRODUCT DESCRIPTION
======================================================================
The Airtac 4V310-10 is a high-performance 5-port 2-position single solenoid pneumatic valve engineered for precision directional control in industrial automation systems. Supplied by VD Valve Sdn Bhd in Malaysia, this model features an internal or external pilot-operated mode housed in a durable aluminum alloy body. It is built with a sliding column structure designed to provide good tightness and a sensitive reaction span. The 4V310-10 includes an orifice size of 28.0 mm² with a flow coefficient (Cv) of 1.65, operating effectively within a pressure range of 0.15 to 0.8 MPa (21 to 114 psi) and a proof pressure of 1.2 MPa (175 psi). Designed to handle filtered air using a 40-micron filter element, this valve requires no additional lubrication during standard operation, although ISO VG32 or equivalent lubricants can be used to optimize lifespan if lubricated air is introduced. With a maximum actuation frequency of 4 cycles per second in a no-load state and a response time of 0.05 seconds or below, it delivers efficient switching performance. The unit accommodates port sizes of 3/8" for In, Out, and 1/4" for Exhaust, with G thread availability as noted in technical documentation. Standard voltage options include DC24V with Class B temperature classification and IP65 protection, making it ideal for integration into manifold assemblies to save installation space across Malaysian manufacturing plants.
