Hunt Strainers are manufactured with the high quality design features required for the severe duty cycles of the Steel Mill Industrial Descale Systems.
The Hunt High Pressure Strainers were developed to avoid the plugging of descaling spray nozzles resulting in rejects of hot strip due to scale streaks. Spray nozzles can easily become plugged if the water contains foreign material. Strainers placed in the line with the descaling valve prevent any foreign material large enough to be harmful from reaching the spray nozzles. They are also used to protect the internal parts of the operating valves. All foreign particles filtered out of the stream of water passing through the strainer are stopped by the grooved rings and collect outside the strainer basket. The basket can be cleaned by removing it from the housing and spraying a jet of compressed air between the rings.
Maximum working pressure (all sizes) is 3600-PSI. Note: as the basket clogs over time, the outlet pressure will drop. This differential pressure must be monitored to avoid damage to the element and subsequent damage to other system components. Filtration rating is 711 Micron.
Installation is allowed in the horizontal or vertical Positions. The strainers are mounted between piping Flanges, no mounting brackets or additional supports are required.
