Detail Information

Product Name: One Piece DBB Ball Valve
Design Standard: API 6D
Body Material: ASTM A105N
Size: 1/2 Inch, DN15
Pressure: Class 900 LB, PN150
End Connection: RTJ
Operation: Lever

Double Block and Bleed (DBB) Valves provide a double isolation function with two obturators inserted into a single body. They feature a bleed/vent system between the obturators (body port and ball, gate, or needle valve), allowing for effective fluid venting. DBB ball valves are designed to shut down a pipe section from both sides of the valve, ensuring safety by preventing accidental leaks that could pose hazards. This design is especially valuable in the oil and gas industry, where it enhances safety while minimizing the need for additional valves, saving both space and costs.
