Specifications:
The Series 3000BM1 consist of a main line valve body composed of two (2) independently acting approved poppet-type check modules with replaceable seats and disc rubbers. Servicing of both check modules do not require any special tools and are accessed via a single top entry cover. The device can be fitted with either approved UL Listed OS&Y Gates or Slow-Turn Gear Operated Ball Valve Assemblies and contains properly located resilient seated test cocks along the main valve body. The auxiliary bypass line contains a 5 / 8 " x 3 / 4 " (16 x 19mm) Water Meter that complies with ANSI/AWWA Standard C700 coupled with an approved double check assembly (DC). The bypass line is design to detect leaks or unauthorized water usage of the fire system while protecting against possible backpressure and backsiphonage conditions for non-health hazard (i.e., pollutant) application.
