Pentair Sudmo pressure relief valve
Designed for the full cleaning of pumps and process lines, the Pentair Südmo pressure relief valve also can be used to prevent backflow in piping or relieve pressure on piping systems. It has an adjustable spring tension that allows the unit to be installed, so it will relieve excess pressure, allowing a pump to recirculate in the event of a process disturbance. During CIP, the valve can be opened to allow access flow around the pump. Hygienic and aseptic variants are available.
