D363H butt welded hard seal butterfly valve
Welding type three eccentric hard seal butterfly valve
1. The use of a triple eccentric butterfly valve can be considered a top-notch process valve, which makes the valve an ideal hard seal butterfly valve with bubble level sealing for high temperature, high pressure, and fire-resistant applications.
2. Due to the use of welding structure, the valve and pipeline plane achieve permanent zero leakage.
3. This valve has no flange, which brings great convenience and aesthetics to pipelines and insulation wrapping.
