MR CEDASPE® DAROC (former ETI)

Shutter valve

The DAROC oil check valve is designed to prevent the oil contained in the conservator from flowing out when a leak occurs and, for Series EDS-R, to signal this by an electric contact. It is fitted on the pipe from tank to conservator, in series with the Buchholz relay, so it can be used on conservators with free oil surface as well as on conservators with air bag. Its operation is completely automatic; when, due to a leakage in the tank, the oil flow rate from conservator to tank exceeds a set value, the DAROC valve closes the pipe thus preventing the loss of the conservator oil.
