The 2" Ames 2000B Double Check Valve Assembly is a bronze bodied, single cover device. It began production in 1997 and is still currently in production. It utilizes a inline check design with a single access cover. Plastic check modules are self contained and are held in place by a retainer directly under the cover. The check modules come apart for service with a quarter turn to the module. No special tools are required for servicing.
