Valves SBB/DBB (Single Block and Bleed/ Double Block and Bleed Ball valve)
SBB (Single Block and Bleed) and DBB (Double Block and Bleed) valves are specialized types of pipe fittings widely used in the petrochemical industry.SBB valves are designed to simultaneously shut off the flow and relieve pressure in the flanged space.
Whereas DBBs perform double overlap with the possibility of pressure relief between two shut-off elements.
This ensures increased safety and efficiency when working with hazardous liquids and gases.
Specifications:
Size: Usually available in sizes from 1/2’ to 12’.
