PWG303876 - DND DC- Replace 8 Chilled Water Valves

The project’s intent is to perform a study leading to full implementation on the feasibility and design options of replacing 8 chilled water valves in the DND Data Centre; once the study is complete, full implementation of the agreed upon recommendation will occur. The valves in question are for the three chilled water pumps from the plant that control primary, secondary & standby pumps. The butterfly valves are stiff and hard to open and close and are at the end of their life expectancy. These pumps supply induction units, and AHU chilled water coils, and the plate heat. The inability to operate these valves will result in not being able to switch primary pumps over to bypass pumps should one go down.
