Original Factory Triple Offset Valve Design - Flange Loose Sleeve Limit Expansion Joints – CVG

Features For Double Flange Loose Sleeve Limit Expansion Joint
▪ The double-flange limit telescopic expansion joint is composed of main components such as the main body, sealing ring, gland, and telescopic short tube.
▪ On the basis of the original performance of the loose sleeve expansion joint, a limit device is added, and a double nut is used to lock at the maximum expansion amount.
▪ The pipeline can expand and contract freely within the allowable expansion and contraction amount. Once the maximum expansion and contraction amount is exceeded, it will be limited to ensure the safe operation of the pipeline. It is especially suitable for connections in pipelines with vibration or a certain slope and bends.
