Description
Return gates are used in pipeline systems as uncontrolled, automatically acting protective devices, serving to prevent the reverse flow of working medium in emergency situations. In working condition the check gate is open under the influence of the working medium flow. In the absence of the working medium flow or when the flow is in the opposite direction, the gate is closed. Operating characteristics, material of manufacture, type of connection, control body depend on technical requirements.
