About this file
This document is a product specification sheet for the Deringer™ 20 Double Check Valve Assembly from Ames Fire & Waterworks, covering sizes 2" to 8". The valve is designed to prevent non-health hazard pollutants from entering potable water supply systems caused by backpressure or backsiphonage conditions. Key features include a 100% stainless steel housing, integral shutoff valves for indoor/outdoor use, tamper-resistant test cocks, and patented Dual-action™ check modules that operate differently under low and high flow conditions.
The specification details the valve's materials, which include 304 stainless steel for the housing and cover, EPDM/304SS disks, and various other components made from materials like PTFE, silicone, and Noryl polymer. The valve operates within a temperature range of 33°F to 140°F and a working pressure of 10-175 psi. It meets several standards including AWWA C510-07, ANSI/NSF/CAN 61, and is UL certified for lead-free compliance. The document provides comprehensive dimensional and performance data, including flow charts, weights, and end connection specifications for different sizes.
