Flange Butterfly Valve
Flanged Medium Line Butterfly Valve with Sulfurized Rubber Seat offers superior sealing performance due to the rubber seat's elasticity, ensuring zero leakage even under low-pressure conditions. Its corrosion-resistant properties make it ideal for handling acidic or alkaline media, while the sulfurized treatment enhances durability and wear resistance. The valve's compact structure saves installation space, and the flanged connection provides robust, leak-proof sealing for high-demand applications.
