Completely redesigned control valves to be launched at Weftec
This company is launching a completely redesigned and technically revised Iris diaphragm control valve (photo) into the North American market. This new series — named IBS — will be presented to a wide audience for the first time at this year’s Weftec. The new valves have a compact structure with a shorter installation length. To aid plant operators in knowing valve positioning, a visual position indicator has been completely revised to be visible from three sides of the valve. The self-lubricating spindle nut design of the IBS enables maintenance-free and cost-extensive operation, thus simplifying the use of the control valve in inaccessible locations. An additional advantage is that operators can replace the drive support without having to remove the valve from the pipe. Its gas-tight design has no spindle feedthrough. Self-cleaning segments also make the valve a reliable regulator for handling raw sewage or sludge, as well as process water, primary and aerated sludge, and also for the task of loading centrifuges with digesting sludge. The three buffer-liquid and flushing connections of the new IBS are offset by 90 deg and can also be used for drainage and emptying condensate, which is a major advantage for plants that are shut down periodically.
