Product Overview
The FESTO VTUG-10-MSDR-S8-S1T-25V20-Q8LA-UL-Q4S-3AL+TT is a high-performance pneumatic solenoid valve manifold from Festo’s VTUG series, engineered for precise directional control of compressed air in demanding industrial automation systems. This valve terminal assembly operates on a 24V DC solenoid actuation principle, utilizing a spool-type directional control mechanism to manage airflow across multiple valve positions. The VTUG-10 platform is renowned for its compact modular design, allowing flexible configuration of valve functions, electrical interfaces, and pneumatic connections within a single manifold block. With integrated UL certification and Q8LA/Q4S port configurations, this unit is purpose-built for North American industrial installations requiring reliable, repeatable pneumatic switching in high-cycle applications.
