Block And Bleed Valve
OTOM Services supplies high-performance double block & bleed valve (DBB valve) systems designed for safe, compact isolation in critical industrial applications. By replacing traditional multiple-valve setups, these DBB valves provide enhanced safety, minimise potential leak points, and simplify maintenance procedures.
Engineered for durability and reliability, they ensure precise isolation of process lines while reducing operational complexity. Ideal for oil, gas, chemical, and other demanding industries, OTOM’s double block & bleed valves deliver efficient, low-maintenance performance without compromising on safety or operational integrity.
Double Block & Bleed Ball
Double Block & Bleed Ball Valves are equipped with a drain needle, ball or DBB valve mounted between the two balls, this permits to drain the valve and reset the pressure to zero.
The main characteristics of this design is double isolation with two independent balls in one valve body, guaranteeing positive shut off with maximum safety with DIB-1, DIB-2 features.
