introduce
With its small piping spacing and space-saving characteristics, it is suitable for use in pipelines and meets customer needs. It uses a separate Teflon seat with a patented design featuring seat pressure compensation and excellent shut-off function. Unlike traditional encased butterfly valves where the rubber ring is prone to deformation and hardening, leading to increased operating torque and leakage, this eccentric butterfly valve allows for seat replacement to suit different system liquids. It also allows for quick addition of thermal insulation materials to meet the anti-condensation requirements of chilled water systems.
