Also known as high-performance butterfly valves, double-offset valves feature two offset stems that offer especially long life due to reduced contact between valve discs and seats. This type of valve can be especially helpful if your operations involve higher pressures and particulate fluids. Our ABZ™ line of double-offset butterfly valves includes the elite 400 and ABZolute high-performance series. These rugged valves are designed to offer improved safety and maximum life even in high-pressure and high-temperature applications. All of our high-performance valves are manufactured to the highest industry technical standards that include the American Petroleum Institute (API), the American National Standards Institute (ANSI) and other international standards of quality.
