The Colt C200Na Double Check Valve Assemblies are used to prevent
backflow of pollutants, that are objectionable but not toxic, from
entering the potable water supply system. The Colt C200Na may be
installed under continuous pressure service and may be subjected to
backpressure. The Colt C200Na consists of two independently
operating check valves, two shutoff valves, and four test cocks. For use
in non-health hazard applications.
Specifications

independent Bi-Link Check modules within a single housing, sleeve
access port, four test cocks and two drip tight shutoff valves. Bi-Link
Checks shall be removable and serviceable, without the use of special
tools. The housing shall be constructed of 304 (Schedule 40) stainless
steel pipe with groove end connections. Bi-Link Checks shall have
reversible elastomer discs and in operation shall produce drip tight
closure against the reverse flow of liquid caused by backpressure or
backsiphonage. Assembly shall be a Colt C200Na as manufactured by
