Series AK/AKH/AKB check valves offer various configurations to provide design solutions based on operating conditions. The series is compact and lightweight with low cracking pressure. The AKH with one-touch fitting, straight type, is easily installed in pipelines, while the male connector type can be mounted directly onto equipment. The bushing type AKB can be used in applications with
