Series LF757DCDA Lead Free* Double Check Detector Assemblies prevent the backflow of pollutants that are objectionable but not toxic, from entering into the potable water supply. Its compact housing consists of two independently operating tri-link check valves, two shutoff valves, and four test cocks. It features a stainless steel housing and sleeve and is 70% lighter than traditional designs. Series LF757 is designed for non-health hazard applications and may be installed under continuous pressure service to protect against both backpressure and backsiphonage. This Series is used primarily on fire sprinkler lines when it is necessary to monitor unauthorized use of water. Maximum Working Pressure: 175psi (12.06 bar).
