ASC's general-purpose ABZ 709/719 resilient-seated butterfly valves are machined to offer long life and resiliency in a slim profile that permits maximum open fluid flow. These sturdy valves meet the strictest industry standards for durability and tight shutoff. The 709/719 valves feature superior sealing features such as unique double-V stem self-seals that protect stem areas during vacuum or pressure use.
Our ABZ valves meet rigorous industry standards that include the American Petroleum Institute (API), the American Society of Mechanical Engineers (ASME) and the American National Standards Institute (ANSI).
