Product Description

1.Application  

The butterfly valve is usually installed between the oil tank and radiator of the oil-immersed transformer to control oil flow between the oil tank and the radiator of the transformer. It is used to open or close the transformer oil circuit when vacuuming oil injection and transformer operation and maintenance. It can also be used in oil discharge in accidents or in maintenance.
 

The vacuum eccentric butterfly valve is mounted in a pipe path between oil-immersed transformer and detachable radiator and cooler or conservator.It is used for opening and closing the oil path and being a vacuum of transformer.
