ASTM A350 LF2 DBB Ball Valve, API 6D, 1 Inch, 1500 LB, RTJ

Product Name: Double Block and Bleed Ball Valve
Design Standard: API 6D
Body Material: ASTM A350 LF2
Size: 1 Inch, DN25
Pressure: Class 1500 LB, PN250
End Connection: RTJ
Operation: Lever

Double Block and Bleed Valves assure double isolation function thanks to two obturators inserted in a single body. They provide the bleed function through a bleed/vent system located between the obturators (body port and ball, gate, or needle valve). Derived from the floating ball valve design, DBB valves are available in several different constructions.
Double block and bleed ball valves (DBB ball valves) allow for a pipe section to be shut down from both sides of the valve. This design feature keeps everyone safe from accidental leaks that can cause harm, making it highly efficient for the oil and gas industry. Along with strong security features, our valves reduce the need for additional valves, saving both space and costs.
