Reverse Valve Series 4C DN 50-450 for Preventing Backflow in Pipelines

Return gates are used in pipeline systems as uncontrolled, automatically acting safety devices, serving to prevent the reverse flow of the 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.
