FB-D-33series Pneumatic High Temprature Flue Gas Valve DNV Butterfly Valve

1. Description:

FB-D-33 series butterfly valves are mainly desulfurization and denitrification systems in Marine and road industrial fields.

FB-D-33 series adopts double valve plate air seal structure design, through the external input of high pressure gas to achie- ve a sealing air curtain on the sealing surface when the valve is closed, so that the valve can achieve zero leakage in the clo- sed state. In addition, in high temperature flue gas lines, this design also reduces the body temperature, which allows the valve to operate more stable and longer in high temperature environments. In the pipeline system with large particle conc- entration, the valve can realize the self-cleaning function of the sealing surface, which can effectively prevent the valve

from being loosely closed due to the accumulation of particles in long-term use.
