Designed for operations and maintenance personnel to perform frequent valve checks, Valve-Squeak is an easy-to-use, pocket-sized through-valve loss detection system. The system isolates leaks of any size and in any valve saving you thousands, if not millions of dollars by indicating no leak with a green light or yellow LED bar graph showing a range of small to very large. Once a leak is detected, a VPACII or VPAC can be used to quantify. The high value of Valve-Squeak means its possible to have many units in a facility to help a single VPACII operator maximize time and resources by quickly identifying and targeting leaking valves for further inspection.
