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.

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.

It is illegal to use this product in any plumbing system providing water for human consumption, such as drinking or dishwashing, in the United States. Before installing standard material prod-uct, consult your local water authority, building and plumbing codes.

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.

909OSY

Series 909 Reduced Pressure Zone Assemblies Sizes: 21⁄2" – 10" (65–250mm) Series 909 Reduced Pressure Zone Assemblies are designed to provide cross-connection control protection of the potable water supply in accordance with national plumbing codes. This series can be utilized in a variety of installations, including health hazard cross-connections in plumbing systems or for contain-ment at the service line entrance. With its exclusive relief valve design incorpo-rating the “air-in/water-out” principle, it provides substantially improved relief valve discharge performance during the emergency conditions of combined backsiphonage and backpressure with both checks fouled.

Features

• Replaceable bronze seats

• Stainless steel internal parts

• No special tools required for servicing

• Captured spring check assemblies

• Fused epoxy coated & lined checks

• Industrial strength sensing hose

• Field reversible relief valve

• Air-in/water-out relief valve design provides maximum capacity during emergency conditions

Available Models Suffix:

BB – bronze body (21⁄2", 3" only) (64, 76mm)

LF – without shutoff valves

NRS – non-rising stem resilient seated gate valves

OSY - UL/FM outside stem & yoke resilient seated gate valves

QT-FDA – FDA epoxy coated quarter-turn ball valves

S – cast iron strainer

S-FDA – FDA epoxy coated strainer

Note: The installation of a drain line is recommended. When installing a drain line, an air gap is necessary.

Specifications A Reduced Pressure Zone Assembly shall be installed at each cross-connec-tion to prevent backsiphonage and backpressure backflow of hazardous mate-rials into the potable water supply. The assembly shall consist of a pres-sure differential relief valve located in a zone between two positive seating check valves and captured springs. Backsiphonage protection shall include provision to admit air directly into the reduced pressure zone via a separate channel from the water discharge channel. The assembly shall include two tightly closing shutoff valves before and after the valve and test cocks. The assembly shall meet the requirements of ASSE Std. 1013; AWWA Std. C511-92; CSA B64.5; and UL Classified File No. EX3185. Listed by IAPMO (UPC). Approved by the Foundation for Cross-Connection Control and Hydraulic Research at the University of Southern California. The assembly shall be a Watts Regulator Company Series 909.
