Triple Offset Flanged Butterfly Valve
【Product Overview】
The D343H-16C Triple Offset Flanged Butterfly Valve is a heavy-duty industrial valve engineered for high-pressure, high-temperature, and tight shut-off applications. Built with a WCB carbon steel body and metal-to-metal sealing structure, this valve offers exceptional durability and zero leakage performance in harsh environments.
Its triple eccentric (three offset) design minimizes seat wear and eliminates friction during opening and closing, making it ideal for throttling and shut-off duties in steam, gas, oil, and corrosive media systems.
