Valves
Durco was founded as the Duriron Casting Company in 1912. Its long history set the standard for ANSI chemical process pumps and robust plug valves. The brand is known for its durable designs, ease of maintenance, proven reliability, wide array of features and an extensive global support network. Complementary seals and seal systems are also available, enabling single-source convenience.
Highlights of Durco’s innovative history include the engineering and manufacturing of the world’s first Teflon® sleeve plug valve in the 1950s. The company has created unique materials, including Durimet-20 (Alloy 20) high alloy austenitic stainless steel — developed and patented in a joint effort with Ohio State University — and Durcomet 100 (CD4MCuN) duplex stainless steel in the 1960s. During the same decade, Durco introduced the first plug and butterfly valves fully lined with Teflon.
In 1997, Durco merged with BWIP, creating Flowserve Corporation.

High-quality valves for any application
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.
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.
