Stainless Steel Double Bleed and Double Block (DBB) Ball Valves
Double Block and Bleed
Double Block and Bleed Ball Valves are aimed to get a double
barrier on the piping, and bleed the fluid trapped between the two
balls from a dedicated drain line. Body construction can be either
forging or centrifugal casting. Wide range of materials: carbon
steels, austenitic or martensitic SS, duplex-superduplex SS,
nickel-based alloys.
Valve design can be either Trunnion or Floating type, anti blow-out stem and typically SPE seat design. Drain port is normally provided with a floating ball valve, to be fitted with Final User drain line. Valve seats can be soft or metal to metal hard-faced.
Size range(s): NPS 1/2 - 2 (DN 15 - 50)
Pressure rating: ASME Classes 150 - 2500
Standard connections: Threaded, socket weld, flanged
