Temperature Range: -196°C to 800°C
D type flange connection, there is a groove on the flange surface of D Flanged Butterfly Valve. Compared with ordinary raised face flange and flat face flange, D type is more firmly connected to the pipe.
Triple Offset Design The triple offset d flanged butterfly valve provides a metal-to-metal or multi-layer sealing mechanism to ensure a bubble seal with minimal wear on the sealing components. This design eliminates friction between the disc and the seat during operation, reduces torque and extends the life of the valve.
High temperature and high pressure design The triple offset butterfly valve features a metal seat, making it ideal for high temperature and high pressure applications. And, it maintains performance even in abrasive and corrosive environments.
The butterfly valve is designed to meet fire protection standards and is suitable for environments such as refineries and chemical plants where fire protection is critical.
