EN Butterfly Valve

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.

 

 

 

EN Butterfly Valve Material Specification

 

 

Valve Body: Constructed from GGG40/GGG50 ductile iron, WCB carbon steel, or stainless steel; features high strength as well as excellent pressure and corrosion resistance.

 

Valve Disc: Made from stainless steel, aluminum bronze, or nickel-plated ductile iron; offers superior wear and corrosion resistance, ensuring a long service life.

 

Valve Seat: Utilizes EPDM, NBR, or PTFE materials; provides excellent sealing performance and is suitable for use with various media and temperature environments.

 

Valve Stem: Fabricated from 420/431 stainless steel; features high torsional strength, corrosion resistance, and ensures stable operation.
