Beschreibung
D371X Schneckengetriebe-Absperrklappe mit weichen Dichtungen in Wafer-Bauweise
The D371X worm gear soft-seated wafer butterfly valve consists of a rubber-lined
valve body, carbon steel or stainless steel butterfly disc and valve shaft. It
is designed for flow regulation and shut-off in water, air, natural gas, oil
products and mildly corrosive fluid pipelines.
The valve is widely used in water treatment plants, power plants, steel mills,
chemical plants, petroleum systems, food processing, textile mills, paper mills
and other industrial water supply and drainage systems. Its compact wafer
construction and worm gear operation make it suitable for applications requiring
reliable sealing and convenient manual control.
