Features
• 70% Lighter than Traditional
Designs
The Maxim M400, M400N, M400Z Reduced Pressure Zone Assemblies provide
protection to the potable water system from contamination in accordance with
national plumbing codes. The Maxim 400, 400N, 400Z are normally used in
health hazard applications for protection against backsiphonage, backpressure
and the fouling of either check valve.
• 304 (Schedule 40) Stainless Steel
Housing & Sleeve
Specifications
• Extremely Compact Design
• Groove Fittings Allow Integral
Pipeline Adjustment
• Patented Link Check Provides
Lowest Pressure Loss
• Unmatched Ease of Serviceability
• Available with Grooved Butterfly
Valve Shutoffs
• Available for Horizontal or N
Pattern Installations
• Replaceable Check Disc Rubber
*The wetted surface of this product contacted by consumable water contains
less than 0.25% of lead by weight.
The 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 shut-off valves, and required test cocks. Link
Check modules and the 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. Assembly shall be Maxim M400, M400N,
M400Z as manufactured by the Ames Company.

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. Approvals
