The Ames Silver Bullet Series Reduced Pressure Zone Assemblies run from 2 1/2" - 10" and are all stainless steel body devices. They utilize a single victaulic cover with two self contained plastic cam checks that thread into the body. There are no check rubber repair kits available for the 2 1/2 - 6" sizes, only complete cam checks. The relief valve simply unscrews off the bottom for service. Although specialty tools are not required for servicing the device, there is a handy cam check tool available, designed to save time and prevent damage to the cam checks. Short lay length and lightweight design make this device one of the industry leaders in recent years for new installation and replacement applications.
