Main applications in the petrochemical field:

· Cryogenic service.

· Low temperature.

· Ambient temperature.

· High temperature.

· Corrosive fluids.

· High pressures.

· Samplings from line.

· Fluids injection.

In conditions of space constraint its more and more important to find compact soluction.As you can see here above one valve is performing the same function of three valves all together and allows a full safety on the line during maintenance operations, not to consider the important reductions of the leakage points on the line.DBB/SBB valves can be used for CHEMICAL,INJECTION AND SAMPLING(through a quill),PRESSURE CONNECTIONS(instrumentation mainly),PROCESS ISOLATION(located in primary process stream).

DBB ball valves produced by NSV are provided in accordance with the following certifications:

· ISO (International Organization for standardization)
