The sealed butterfly valve BDB-150/80 is mainly used to connect components such as oil immersed transformers, coolers, radiators, and oil storage tanks to oil pipelines. Its function is to open or close the oil circuit during vacuum oil injection and operation maintenance of the transformer. When the transformer is operating normally, the valve opens; When the transformer malfunctions, is transported or repaired, the valve is closed. This valve has good overall rigidity and long service life characteristics. It adopts a fully sealed inclined contact design, with fine processing and excellent sealing performance.
