What is the difference between soft-sealed and hard-sealed flanged butterfly valves?

Soft sealing: Mostly adopts a centerline design, relying on the deformation of elastic materials to compensate for irregularities on the sealing surfaces; the structure is simple. Hard sealing: Typically employs single-eccentric, double-eccentric, or triple-eccentric designs, leveraging the metal wedge effect to enhance sealing performance, with high requirements for machining accuracy.

Installation Details for Direct-Buried Bellows Compensators

Bellows expansion joints, also known as bellows compensators, are classified as precision components. As one of the key components used in modern heated pipeline networks and equipment for thermal compensation (axial, lateral, and angular displacement), the thermal compensation performance of a compensator is determined by the bellows.
