SBB Ball Valves (Single block &bleed)

Single block & bleed ball valves are mainly suitable for the instrumentation and particularly required thanks to the balls seal monitoring capability.

Thanks to a SBB ball valve, it is possible to  avoid  an additional  needle valve having the same result reducing costs,  overall dimensions and the ability to bleed off the plant, by controlling a potential leakage of the plant.

Single block & bleed valves are recommended for low pressure classes ensuring long-lasting seal.

Floating type valves are more often required, however it is possible to supply the Trunnion version valve, too.

Main applications in the petrochemical field:

• Cryogenic service.
• Low temperature.
• Ambient temperature.
• High temperature.
• Corrosive fluids.
• High pressures.
• Samplings from line.
• Fluids  injection.

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.

Valves are built in any steel required by the Customer and defined in the data sheet provided in the quotation request.

SBB ball valves produced by Etiovalves are provided in accordance with the following certifications:

• ISO (International Organization for standardization)
• PED (Pressure Equipment Directive)
• ATEX (ATmosphères EXplosibles)
