DLF Series Shut-off Valve

Shut-off valve, also known as flow control valve, is a mechanical flow control type  one-way check valve. It is usually installed in the pipeline between the transformer and oil conservator. When the transformer due to internal failure or other reasons   results in a large amount of oil overfall or leakage, the flow control valve has the
function of “Shut down once oil is discharged”, can cut off the oil path between   oil conservator and transformer tank immediately, so that the oil conservator will no longer fill the tank. It is a very ideal auxiliary safety protection device for oil-    immersed power transformer.
