Specification

SEODescription

The QST-1/4-8 valve by Festo is a compact 1/4 inch pneumatic valve designed for industrial automation, featuring eight pneumatic output ports and four digital control inputs. Compatible with Festo pneumatic connectors, it supports direct integration into modular pneumatic systems, enabling seamless control of multiple actuators. Operating within a voltage range of 12-24V DC and a temperature range of -10°C to 60°C, this valve is ideal for manufacturing, packaging, and assembly lines. Its key advantages include high flow efficiency, durable construction, and easy installation via standardized 1/4-inch interfaces. However, it lacks built-in communication protocols, requiring external controllers for networked operations. The valve excels in environments demanding precise, reliable pneumatic control with minimal space requirements.
