Product description

Used in power oil transformers, autotransformers and reactors, installed in the oil line between the oil expander and the main tank. It is designed to automatically limit oil flow from the oil conservator, if the oil flow rate from the oil conservator to the tank exceeds the setpoint.

Operating principle

The actuating element of the valve is the float. Oil flowing through the valve from the oil conservator into the tank acts on this float. When the oil velocity reaches a certain value (valve set point), the force exerted on the float by the oil flow will exceed its buoyancy and the valve will close.
