Product Description
Product Overview
The double eccentric butterfly valve represents an advanced evolution from single eccentric designs, featuring valve stem axes that deviate from both the butterfly plate center and body center. This dual offset configuration enables rapid disengagement from the valve seat upon opening, minimizing excessive compression and scraping while reducing operational resistance and wear. The design significantly extends valve seat service life and enables the use of metal seats for high-temperature applications up to 110°C.
