Apollo™ Backflow Preventer, Series: RP40, 1/2 in Nominal, 175 psi, 33 to 180 deg F, Reduced Pressure Backflow Type, Stainless Steel Body, 3-3/16 in W, Domestic
The Apollo Series RP 40S Stainless Steel Reduced Pressure Principle Backflow Preventer is designed to give maximum protection against backflow caused by either backpressure or back siphonage from a cross-connection wherein a contaminant hazard exists (i.e. a health hazard), or a pollutant hazard exists (i.e. a non-hazard). The assembly is composed of two spring-loaded poppet type check valves and a mechanically independent, hydraulically dependent pressure differential relief valve set in an integral stainless steel body. Three of the test cocks are mounted at the top to assure easy access during repair and maintenance when unit is installed in tight places.
