Apollo RPDALF 4AN N Style Reduced Pressure Detector Backflow Preventer Assembly

Item Code: ARPDALF-4AN
The Apollo Model RPDALF 4An Reduced Pressure Detector Assembly consists of twoindependently acting, TriForce™ center stem guided check valves with a differential pressurerelief valve located between the check valves. The unit is designed to give maximum protectionagainst backflow of health or non-health hazard fluids by either back-pressure or back-siphonageand at the same time detect leakage or unauthorized use of water from fire or automatic sprinklersystems. The normally vertical up/vertical down oriented body incorporates an internal swivelconnection providing the ability to pivot the second check 180° to a vertical up/vertical up flow.The durable domestic stainless steel units (2-1/2” to 8”) and the FDA epoxy coated ductile ironunits (10” and 12”) are easily maintained in the line without any special tools. The TriForce™ checkvalves operate with a spring assist in the flowing condition to provide low flow rates which aredocumented by an independent laboratory.Available in both Type 1 and Type 2 bypass configurations. The Type 2 bypass uses the first checkof the mainline assembly as the first check of the bypass. The second check of the bypass is asingle check valve with a model number and serial number for test recording. This arrangementcomplies with the National Backflow Standards. The arrangement provides the same level ofprotection as the Type 1 bypass and the testing procedure is the same.
