Seals inside quarter-turn valves become damaged over time. Chemical incompatibility between the seal and fluid causes seals to split or swell. Mechanical wear due to frequent valve cycling reduces the size of the seal.
Today’s manufacturing plants experience unplanned downtime when these seals are damaged and product leaks through the valve. In many cases, the problem isn’t detected until further downstream when the product is tested and quality is poor. This results in all in-process product to be scrapped. What if a sensor could predict when the valve will fail?
Detect build-up of foreign materials
Poor raw material supply quality, sticky or viscous media, a waste system that must accommodate solids/oils, or a corroded pipe can all prevent a valve from closing completely. The ability to monitor the closed position of a valve can save tens of thousands of dollars in scrapped material and downtime to replace the valve. Productivity and cycle time can also be affected as the time to close the valve increases with build-up.
Fast and simple installation
Downtime is expensive. With the MVQ sensor, ifm provides the simplest mounting concept in the industry.
