Series C300 double check valve 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 trilink check valves, (2) shutoff valves and (4) test cocks. It features a stainless steel housing and sleeve and is 70% lighter than traditional designs. Series C300 is designed for non-health hazard applications and may be installed under continuous pressure service to protect against both back pressure and backsiphonage.
