This 10 inch Ames Fire & Waterworks Series 2000SS Double Check Valve Backflow Preventer Assembly is engineered to prevent polluted water from entering potable systems. Featuring a durable 300 Series stainless steel body and Noryl® check assembly, it offers superior corrosion resistance and a lead-free wetted surface. The compact, modular design with cam-check valves ensures low head loss and easy maintenance without special tools. Approved for non-health hazard applications, it can be installed horizontally or vertically. It includes domestic OSY shutoffs and an optional integrated supervisory switch, making it suitable for continuous pressure service at service line cross-connections. Item number 0692774.
This 10 inch lead free double check valve backflow preventer assembly is designed to prevent the reverse flow of polluted water from entering the potable water system, effectively safeguarding against backsiphonage and backpressure in non-health hazard installations.
Key Features
Features a stainless steel body and cam-check assembly for low head loss and long-term corrosion protection.
Its compact, modular design with short lay length is ideally suited for retrofit installations and allows for installation in smaller vaults and enclosures.
Equipped with domestic outside stem and yoke (OSY) resilient seated gate valves.
Includes an option for an integrated supervisory switch on each gate valve of the OS&Y model.
Construction & Maintenance
The main valve body and all internal metal parts are constructed from 300 Series stainless steel, ensuring maximum strength and reduced weight compared to competitive designs.
The check assembly uses Noryl® material.
The wetted surface contains less than 0.25% lead by weight, making it lead free.
Maintenance is simplified with a single top access cover and two-bolt grooved style coupling, requiring no special tools for servicing.
Inquire with governing authorities for local installation requirements and thoroughly read all installation and safety information before use.
