RP 4A SERIES REDUCED PRESSURE PRINCIPLE
The Apollo Series RP 4A Reduced Pressure Principle Backflow Preventer is
designed to give maximum protection against backflow caused by either
back-pressure or back-siphonage from substances that are hazardous.
The durable but economical device is easily maintained in the line with
modular check cartridge assemblies that require no special tools. It consists
of two independently acting spring-loaded check valves with an automatic
differential relief valve located between the check valves. All testcocks
are mounted at the top of the unit to assure easy access during repair and
maintenance when unit is installed in tight places.
