ZHONGNAN VALVE
Triple Eccentric Extended Stem Butterfly Valve
Supports customization, the triple eccentric extended stem butterfly valve is a high-performance butterfly valve with advanced structure and reliable sealing. The valve adopts a triple eccentric design, allowing the valve disc to operate with almost no friction during opening and closing, ensuring a longer sealing surface lifespan. The extended stem structure facilitates operation in underground pipelines, deep wells, and environments with thick insulation layers, ensuring valve reliability while improving installation and maintenance convenience.
ZHONGNAN VALVE
Double Eccentric Extended Stem Butterfly Valve
Supports customization. The double eccentric extended stem butterfly valve is based on the double eccentric butterfly valve, equipped with an extended operating lever or extended valve stem structure, enabling operation in special conditions such as long-distance, underground wells, or buried environments. The double eccentric design effectively reduces friction between the valve disc and the sealing ring, allowing flexible opening and closing, reliable sealing, and long service life.
