The EN Butterfly Valve is an industrial pipeline control valve that complies with EN standards.
- Product Introduction
EN Butterfly Valve Overview
The EN Butterfly Valve is an industrial pipeline control valve that complies with EN standards. Constructed from ductile iron, carbon steel, or stainless steel, it utilizes the rotation of a disc to control the flow of media-facilitating both shut-off and flow regulation-and is widely employed in water supply and drainage, HVAC, chemical processing, and various industrial systems.
