Abstract: Provided are an apparatus for managing a dual level reset of a microgrid gateway for a new generation energy management system and a method thereof. That is, according to the present invention, it is possible to help a stable operation until a person for maintenance arrives on the scene to take action even though a fail occurs in the system by determining whether the system normally operates and enhance stability of a gateway, by performing a reset function for the entire system when a software defect other than a hardware defect is verified.

Abstract: A pneumatic valve includes a cylinder having at least one gas port for providing inflow and outflow of a gas; a piston arranged in the cylinder and performing a reciprocating, straight-line movement in response to the inflow and outflow of the gas; a first valve shaft passing through the piston and having a first end portion including a first coupling portion; and a second valve shaft including a second coupling portion and having a first end portion protruding from the cylinder, wherein the second coupling portion is coupled to the first coupling portion.
