Advantages of Double Block and Bleed Valves

Advantages of Double Block and Bleed Valves We engineer top standard KP-LOK double block and bleed valves made to match process needs. All DBB valves are produced under control of ISO 9001 to make sure process integrity KP-LOK double block and bleed valve . Why DBB are best? DBB control devices give a single valve that can simultaneously cut isolate/off the upstream and downstream systems. In the block and bleed configuration, ball valves or needle valves are used as drain valves or bleed control devices while ball valves are used as block and isolation valves. Double block and bleed valves give positive zero leakage and shut-off which makes them perfect for product metering, aviation fueling, product isolation, lockout/tagout, blending, tank storage, manifolds product and other applications. Double block and bleed valves are manufactured and designed to ASME B16.34, API 6A/6D, API 6FA, API 607, API 598. Each DBB and bleed control device is hundred perfect factory tested and verified for use in commercial and industrial applications. In order to specify a DBB, you must have an understanding of your result. Picking the valves for your project can be challenging. Valves can support you pick the best valve for your application. Benefits of double block and bleed valves DBB are perfect for critical process and largely used for dangerous fluids and top force systems. Applications where double block and bleed control devices and DBB are used contain chemical seal isolation, gauge isolation, chemical injection connection, chemical seal isolation, sample connection, direct mounting of instruments, gauge isolation remote mounting of tools and tool drain. Double block and bleed control devices decrease costs of installation and permit fewer likely paths for leakage matched to old control devices installations. Double block and bleed control devices full the job that would generally need 3 separate valves - two isolation and one drain which means that less area is needed for them. • Reduced system vibration • Reduced gasket and bolting • Supporting brackets are not needed • Increased system reliability • Design becomes more compact • Better personnel and plant safety. Features • Working force up to 10,000 psig • Compact needle valve/ball valve and OS&Y assembly in single DBB. • Every control device is subject to a force test in accordance with the standard BS 6755 or API 598. • Force rating as per ASME B16.34 • NPT threaded linked to ASME/ANSI B1.20.1. • Fire checked as per BS6755 part 2 • Anti static gadget is set between the ball and stem • Reduced future leak path with secondary and primary isolation in one control device • Flange construction as per the need of ASME B16.5 flange links comply with EN 1092-1 are also accessible upon request. The big advantage would be that the new DBB pipeline ball control device has the same face-to-face dimension as a one block ball control device. The length of a one block ball control device in API 6D and ASME B16.10. As a consequence the control device can simply be installed into an existing pipeline without the need for any re-work on the pipeline.
