UNOX Lug Type Double Acting Pneumatic Actuator Nickel Butterfly Valve

What is a Pneumatic Actuator Lug Type Butterfly Valve?

A butterfly valve is used to control the flow of liquids or gases such as water, air, or gas. It consists of a disc that rotates around an axis. When the disc is open, it allows flow, and when closed, it restricts or stops the flow. Thanks to this simple operating principle, butterfly valves are widely used in large-diameter piping systems in industrial facilities.

Pneumatic actuator lug type butterfly valves are designed for water and non-corrosive fluid applications, especially in narrow installation areas. They are lug and wafer type valves installed between two flanges and operated by compressed air through a pneumatic actuator. These valves are available in different connection sizes and disc material options such as brass or stainless steel, depending on the application requirements.
