The VariAS-Block type most commonly used is the Double Block and Bleed Design with a primary and a secondary isolation ball valve
design and a metal seated needle vent valve.
The welded ball valves
will be mainly used in a project relating to 2*100 MW back pressure heating transmission unit.
The new six-way control ball valves
from Siemens have a built-in pressure compensation function which is active when the valve is in the closed position (ie when no heating or cooling is needed).
Located in Hudson, Massachusetts, the company offers a wide variety of valves, including ball valves
