Positive Isolation Block and Bleed Valves


SWI positive isolation block & bleed valves are designed to overcome the problems of traditional valve assemblies that are used for primary isolation duty. By combining the piping and instrument valves in a single assembly, the block and bleed valves offer weight and space savings with the additional benefits of reduced leakage and safe installation. The compact design reduces the piping vibration and associated stress to provide the highest integrity for critical services.
