Flanged Forged Steel Double Block and Bleed DBB Ball Valve (DBBQ41F)Specification
Design standard: ANSI B16.34     GB/T12237
Physical dimension: ANSI B16.10    GB/T12221
Flanges dimension: ANSIB16.10     GB/T15188.1
Test and inspection: API598        GB/T909
 
 Flanged Forged Steel Double Block and Bleed DBB Ball Valve (DBBQ41F)structure characteristics

1. The double block and bleed valve have evolved to replace and add the process of bolting together individual valves to make the valves in one body .it saved a lot of space and material.
2. Special designs including injecting quills ,sample probes ,double block and single block, in-built check valves and seat wipers.
3. Dual isolation is necessary requirement when maintenance is taking place down stream of the first isolation valve. Cavity venting is provided by either a ball or globe OS&Y vent valve so that trapped pressure between the two isolation valves is safely vented.
4.  These valves have also evolved to encompass the function of chemical injection (using a suitable quill) and sample points .In-built check valves are often integrated in these valves.
5. Fire Safe according to BS6755/API 6FA/API 607, since each sealing point is provided by a secondary fire-safe seal in graphite. Valve soft seats also are provided with secondary metal-to metal seal in case of fire.
6. Valve design can be either Trunnion or floating type ,anti blow -out stem and typically SPE seat design .Drain port is normally provide with a floating ball valve ,to be fitted with final user drain line .valve seats can be soft or metal to metal hard-faced. 

 Flanged Forged Steel Double Block and Bleed DBB Ball Valve (DBBQ41F) Standards compliance:
                                      Design and Manufacture: API 608, API 6D
                                      Face to face(end to end): ANSI B16.10, API 6D
                                      Flanged connection: ANSI B16.5
                                      Fire-safe: API 607,API 6FA
                                      Butt welded end: ANSI B16.25
                                      Test and inspection: API 598,API 6D
 
 Flanged Forged Steel Double Block and Bleed DBB Ball Valve (DBBQ41F) Advantage:
1. The fluid resistance is small, its resistance coefficient with section of equal length.
2. Simple structure, small volume, light weight.
3. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.
4. Easy to operate, open and close quickly
5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.
6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.
7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
