Three additional sizes have been added to the company’s UL/FM check valves
To meet the higher pressure requirements of today’s water infrastructure systems, all 2- to 12-inch Mueller UL/FM swing check valves are now rated at 350 psig cold working pressure (CWP). In addition, the product line has been expanded to include 2-, 14-, and 16-inch sizes (with the largest two sizes still rated at 250 psig CWP). Standard features of Mueller UL-listed, FM-approved check valve product line now include: all ductile iron construction, bronze to BUNA seating, lifting rings, PN16 drilling, bosses for bypass connections, and a drain plug.
With a gravity operated, swing check design, the valves are designed to allow access to all part through the top of the unit, according to the company’s website.
Earlier this year, Mueller purchased Canadian valve manufacturer, Singer, for €24.2 million.
