Operation: Lever

The Double Block and Bleed (DBB) Valve ensures reliable double isolation through two obturators within a single body, complemented by a bleed/vent system located between the obturators (body port and ball, gate, or needle valve). This innovative design supports efficient isolation and venting functions, making it particularly suited for applications requiring high safety standards, such as the oil and gas industry. The DBB valve design minimizes the risk of accidental leaks, enhances security, and reduces the need for additional valves, saving both space and costs. Additionally, DBB floating ball valves enable isolation of a pipe section from both sides of the valve, ensuring enhanced operational safety and performance.
