The assessment of valve closure has always been of concern to water utilities and councils, as valve exercising cannot accurately determine whether a valve has full closure or partial closure. The condition of critical valves is, however, of highest importance as they must be able to be operated, closed and isolated in case of a catastrophic mains failure.
v-CAT™ is an innovative technology to assess the sealing condition of valves. v-CAT™ possesses a unique method to accurately locate and determine any valves of poor performance, based on the reflection of a transient signal travelling along the pipeline.
v-CAT™ can be applied on any pressurised fluid filled pipeline carrying potable, raw or waste water. v-CAT™ is most suitable for metallic, concrete and AC pipes.
