The GENERAL VALVE® is a high-integrity positive shut-off Double-Block-and-Bleed valve designed for custody transfer for the petroleum, oil and gas industries.
Introduced in 1941, GENERAL VALVE® Twin Seal plug valves were the first to meet the rigid requirements of double block-and-bleed service. In the years since, subtle yet significant design refinements have further improved valve performance. Superior design innovations, pride in manufacturing workmanship, and selection of the best materials support our commitment to excellence and customer satisfaction.
