Product Details

NSV Double Block and Bleed Ball Valves(DBB BALL VALVES) are mainly suitable for the instrumentation but also required as an alternative to the in-line installation of two valves.

DBB VALVES assure double isolation function thanks to two obturator inserted in a single body and they provide the bleed function by means of a bleed/vent system located between obturators(body port and ball,gate or needle valve),from the floating ball valve design,that with several different constructions.

Double block & bleed valves DBB are recommended for any pressure class and ensure long-lasting seal.

They can be supplied both in the Trunnion and in the Floating version.

These valves can be designed to meet with Customer’s requirements: for instance, they may be buried in the ground and made operable by the extensions.

Material: A105,F304,F316,ETC.
Size Range: 1/2"~2",large sizes on request

Design Description:
- Integral,Two or Three Pieces Body
- Metal or Soft Seated
- Full or Reduced Bore
- Flanged or NPT Ends
- Anti Blow Out Stem
- Anti Static Device
- Fire Safe Design

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)

· PED (Pressure Equipment Directive)
