Double isolation with integrated bleed function
Industrial valves
Double Block & Bleed
Ball Valves.
Reliable process isolation with integrated bleed for safe maintenance.
Designed for critical service applications where positive shut-off, pressure isolation and safe venting are essential.
Critical isolation
Double isolation.
Safe and efficient maintenance.
Double Block and Bleed (DBB) Valves are designed for critical process isolation applications where reliable shut-off, pressure isolation and safe maintenance are required. These valves integrate two independent isolation barriers with an intermediate bleed or vent connection, providing a compact and efficient alternative to conventional multiple-valve arrangements.
DBB Valves are widely used in oil & gas, petrochemical, chemical, power generation, refineries, process industries and instrumentation systems where positive and verifiable isolation is important.
SGM Corporations supplies Double Block and Bleed Valves for industrial applications with configurations selected according to the required size, pressure class, temperature, material, connection and process conditions.
