The Colt C400, C400N, C400Z Reduced Pressure Zone Assemblies provide
protection to the potable water system from contamination in accordance with
national plumbing codes. The Colt C400, C400N, C400Z are normally used in
health hazard applications for protection against backsiphonage, backpressure and
the fouling of either check valve. The Colt C400, C400N, C400Z features Lead Free*
construction to comply with Lead Free* installation requirements.
Specifications
The Colt C400, C400N, C400Z Reduced Pressure Zone Assemblies shall consist
of two independent Link Check modules, a differential pressure relief valve located
between and below the two modules, two drip tight shutoff valves, and required
test cocks. Link Check modules and relief valve shall be contained within a sleeve
accessible single housing constructed from 304 (Schedule 40) stainless steel pipe
with groove end connections. Link Checks shall have reversible elastomer discs and
in operation produce drip tight closure against the reverse flow of liquid caused by
backpressure or backsiphonage. Lead Free* Reduced Pressure Zone Assemblies
shall be constructed using Lead Free* materials. It shall comply with state codes and
standards, where applicable, requiring reduced lead content. Assembly shall be Colt
C400, C400N, C400Z as manufactured by the Ames Company.

Capacity
Flow capacity chart identifies valve performance
based upon rated water velocity up to 25fps
• Service Flow is typically determined by a rated
velocity of 7.5fps based upon schedule 40 pipe.
• Rated Flow identifies maximum continuous duty
performance determined by AWWA.
• UL Flow Rate is 150% of Rated Flow and is not
recommended for continuous duty. • AWWA Manual M22 [Appendix C] recommends
that the maximum water velocity in services be
not more than 10fps. UL/FM Certified Flow Characteristics
N&Z Flow characteristics collected using butterfly shutoff valves.
