The DBB (Double Block and Bleed) Ball Valve from KIZI is a high-performance solution designed to provide safe, efficient, and precise fluid isolation for complex industrial systems. Built to meet stringent international standards such as API 608, ASME B16.5, and API598, this valve ensures exceptional sealing reliability and long service life even under harsh operating conditions.
The DBB Ball Valve integrates two independent shut-off mechanisms within a single body, allowing complete isolation of both upstream and downstream flow lines while simultaneously providing a bleed function to drain trapped fluid. This innovative design eliminates the need for multiple valve installations, reducing space requirements, installation costs, and maintenance complexity. It is ideal for systems that demand absolute sealing integrity, such as petrochemical plants, natural gas pipelines, oil refining facilities, and energy generation environments.
Constructed from high-grade stainless steel or carbon steel, the valve offers excellent resistance to corrosion, pressure, and temperature fluctuations, ensuring stable performance from -20°C to 200°C. Its full-bore design minimizes pressure loss, while the precision-machined ball and seat assembly guarantee smooth operation and tight sealing even after long-term use. The ISO 5211 mounting pad enables flexible automation options with pneumatic or electric actuators, catering to modern process control systems.
In addition to its robust mechanical structure, the DBB Ball Valve features user-oriented benefits such as easy maintenance, simple actuation, and compatibility with multiple media including oil, gas, steam, and water. These valves are also designed with safety in mind—equipped with anti-blowout stems, fire-safe sealing, and leakage prevention measures that meet international safety regulations.
For buyers seeking reliability, efficiency, and low lifecycle costs, Kizi’s DBB Ball Valves represent a smart investment. They enhance operational safety, improve energy efficiency through optimized flow control, and reduce downtime thanks to their long-lasting, low-maintenance design. Whether installed in chemical pipelines or high-pressure distribution systems, DBB Ball Valves deliver performance and trust that align with Kizi’s long-standing commitment to quality and innovation in fluid control engineering.
