It is a valve, which can automatically cut off the oil delivered from the oil conservator to the oil tank if the flux of oil suddenly increases. This shutter activates automatically while an enormous amount of oil is leaking from a broken oil tank due to a transformer accident. Shutter is installed between the oil conservator and the gas relay and connected by flanges. An electric signal will be delivered to FMD Control Box if shutter activates. Shutter has to be reset manually after being used.
