Lined Butterfly and Plug Valves

Durco’s comprehensive portfolio of non-lubricated and lined plug valves is designed to handle the most corrosive and challenging chemical services where drop-tight shutoff is an absolute necessity. The rugged design of Durco valves reduces maintenance, ensures longer service life, and is capable of adjustment inline under pressure. Operational expenses are reduced by the self-wiping action of the plug sleeve, which eliminates media buildup on the plug. The potential for leakage is reduced by a tapered wedge design, which provides excellent upstream and downstream sealing capabilities.

The Durco TX3 butterfly valve offers excellent shutoff capabilities with the low torque and reduced wear benefits of a triple offset design. The precision seat and seal are machined at an offset angle, creating even seat loading around the entire seat ring and eliminating rubbing between the seat and seal during opening and throttling. Combined with its laminated seal ring, the Durco TX3 valve’s triple offset design provides long-lasting, bi-directional, bubble-tight shutoff, even in gas applications.

Durco offers the largest variety of materials in the industry, providing reliable, high-quality valves for any application. An extensive range of special application variants includes valves for hydrofluoric acid (HF) alkylation, oxygen, isocyanates, slurries, phosgene, and many more.
