Pneumatic Actuated Lug Type Butterfly Valve
A butterfly valve is used to control the flow of liquids or gases, such as gas, water, or air. It consists of a pair of discs that rotate around an axis. When one disc is open, the other is closed, which allows for flow control. Butterfly valves are commonly used in large pipelines or hoses, often in facilities, factories, and industrial plants to control the flow of substances like water, gas, or air.
Pneumatic Actuated Lug Type Butterfly Valves are preferred in narrow spaces for non-corrosive fluid applications. These valves, made with brass or stainless steel disks, are manufactured in wafer and lug types and feature flange connections. They are pneumatically actuated, with varying connection diameters, and are operated by air supply.

Butterfly Valve Construction:
-
Aluminum Extrusion: The cylinder surface is processed with a highly precise technique for internal and external corrosion resistance, long lifespan, and low friction coefficient.
-
Symmetric and Easy Assembly Position: Allows for quick operation and the ability to change piston direction simply by repositioning it. The compact pistons are made from special aluminum alloys.
-
Mounting at 45°-90° Angles: Symmetric, corrosion-resistant high-quality steel pinion for compatibility with every angle of installation.
-
Low Friction Bearing Elements: Made from industrial-grade plastics, these elements minimize wear on friction surfaces.
-
Silent Operation: Precision-machined module gears for the piston and pinion, ensuring high efficiency with minimal noise.
-
Durable Stainless Steel Components: Long-term corrosion resistance with stainless steel connection elements.
The valve design complies with the latest specifications, and solenoids, limit switches, and other accessories can be easily mounted and demounted. These valves adhere to standards such as ISO 5211, DIN 3337, and VDI/VDE 3845 NAMUR.
