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:
Samplings from line.
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.
