D371X worm gear soft-seated wafer butterfly valve is designed for reliable flow regulation and shut-off in water, air, natural gas, oil and mildly corrosive fluid pipelines. With a compact wafer body, low operating torque, replaceable rubber seat and bidirectional sealing, it is suitable for PN6, PN10 and PN16 industrial applications.
-
D673H pneumatic triple-eccentric butterfly valve features a flexible stainless steel U-shaped sealing ring and a polished disc with three-dimensional eccentric geometry. The sealing surface separates immediately when the valve opens and makes contact only when closing, reducing friction and extending service life. It is suitable for high-temperature, corrosive and demanding applications up to 550°C in metallurgy, power generation, petroleum, chemical processing, gas, air and water systems.
