New Stainless Steel Cover Plates Provide Enhanced Corrosion Protection

Friday, April 27, 2018 - 2pm


Hastings, Michigan, USA – The Viking Corporation, a global leader in fire protection and life safety systems, has enhanced its leading line of concealed pendent sprinklers with the introduction of new stainless steel cover plates.

The new stainless steel flat cover plates are available for Viking’s Mirage® Model VK462 and Model VK538 Concealed Pendent sprinklers, and the Freedom® Model VK494 Residential Concealed Pendent sprinkler.  Both large (3-5/16”) and small (2-3/4”) diameter cover plates are offered in stainless steel. (Model VK538 available with large version only.) The stainless steel cover plates are UL Listed for use with Models VK462, VK538, and VK494, and are also FM Approved for use with the VK462.

The new stainless steel cover plates can be used with standard brass models, however, combining them with ENT plated concealed sprinklers creates an enhanced concealed sprinkler assembly  providing an even higher level of overall resistance to corrosion. This assembly is well-suited for many applications where corrosion is a possible concern, such as food and pharmaceutical processing, food service areas, industrial wash down areas, parking garages, saunas, locker rooms, and sprinkler system installations near the ocean.

Stainless steel cover plates for Models VK462 and VK538 are available in both 135°F and 165°F temperature ratings. The VK494 stainless steel cover plate is available in 135°F only. Installers should refer to Viking’s Concealed Sprinkler Cover Plate Assemblies Technical Datasheet F_040600 for complete information on sizes, temperature ratings, and available finishes.
