There are a variety of mitigating solutions that can result in a significant decrease in the number and frequency of pipe bursts within a water utility’s distribution or transmission system. This paper focuses on several solutions and offers a brief explanation of the applications and intricacies of the associated equipment. An overview is also given of non-diaphragm operated control valve solutions, along with background information that includes the advantages and disadvantages of the different types of equipment.
This white paper will deal with cavitation solutions as they relate to valves and specifically pilot-operated automatic control valves. A high-level description of what causes cavitation and the associated impacts will be covered. Typical occurrences of cavitation and consequences will also be discussed in some detail. A brief history of cavitation solutions will be explored so an understanding of past practices will be fully understood.
