Ames 4000CIV/5000CIV
Series 4000CIV 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 containment at the service line entrance. With its exclusive patented relief valve design incorporating 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. Maximum Working Pressure: 175psi (12.06 bar).
Size Range: 2 1/2 to 10 in. (65 to 250mm)

Series 5000CIV Reduced Pressure Detector Assemblies prevent the reverse flow of fire protection system substances from being pumped or siphoned into the potable water supply. The 5000CIV incorporates a meter to detect ground leaks and unauthorized illegal taps, greatly reducing annual water expenses.
