What is Manual Flanged Centerline Butterfly Valve
The manual center-line flange butterfly valve consists of a valve body, butterfly plate, valve stem, rubber valve seat, and drive unit. The valve seat adopts a movable, embedded design, and can be selected from materials suitable for high temperature resistance, low temperature resistance, corrosion resistance, light resistance, and aging resistance, depending on the physical and chemical properties of different media. It can be widely used in municipal, construction, air conditioning, food, pharmaceutical, chemical, petroleum, power, light textile, and papermaking industries for water supply and drainage, and gas pipelines to regulate flow and cut off media.
Features
● Novel and rational design, unique structure, lightweight, low operating torque, and rapid opening and closing.
● Can be installed in any orientation without restriction.
● Movable, embedded valve seat design for easy replacement.
● The valve seat and valve body are equipped with interlocking grooves to prevent valve seat slippage and ensure reliable bidirectional sealing with zero leakage.
● Multiple integrated sealing rings at the valve seat shaft hole ensure reliable valve shaft sealing.
● The valve shaft and butterfly plate use a pinless connection to prevent internal leakage.
● Flexible operating mechanism options; manual, electric, and pneumatic operation modes can be configured according to customer needs.
