该阀执行双重截止阀和放气阀功能，由两个单独的隔离球阀和一个排放阀组成一个单元。与在过程管道应用中使用三个单独的阀的传统方法相比，这种三件式结构具有节省空间和减轻重量的优点。The valve performs double block and bleed valves function and consists of two separate isolating ball valves and one drain valve in one single unit. This three piece construction offers space and weight saving benefits over the traditional method of using three separate valves in process piping applications.
这些阀按API 6D标准提供。These valves are supplied to the API 6D standard.
