Double Block and Bleed Valves

The Dublok ball valve double block and bleed assembly has three valves - primary isolation, secondary isolation and bleed - all integrated into a single block. If required the inlet or outlet end connection can incorporate a spring loaded in-line piston check valve. The end connectors are interchangeable and can be specified to suit exact requirements. Our ball valve double block and bleed assembly is very compact and is recommended for general services. We can, however, incorporate needle, globe and gate valves into the design to suit particular duty specification.
