All Metal Flange Butterfly Valve
Nominal Diameter: DN 50 ~ 1200 mm
Nominal Pressure: PN 0.6 ~ 2.5 MPa
Applicable Mediums: Water, oil products
Applicable Temperature: ≤ 650°C
All Metal Flange Butterfly Valve
The All Metal Flange Butterfly Valve is specifically engineered for severe service applications involving high temperatures, high pressures, abrasive media, and corrosive environments. Featuring a fully metallic seat and sealing structure, the valve delivers exceptional durability, reliable shut-off performance, and extended service life under extreme operating conditions where conventional soft-seated butterfly valves cannot perform effectively.
The flanged connection design ensures secure installation, excellent structural strength, and easy integration into industrial pipeline systems. Its quarter-turn operation provides fast opening and closing, making it ideal for both isolation and flow control applications.
We offer comprehensive OEM and ODM services to meet the diverse requirements of global industrial customers:
Our All Metal Flange Butterfly Valves can be manufactured and tested in compliance with international standards:
