Description
These devices shall have a hot and cold water inlet, and a hot and cold water outlet. These devices equalize incoming hot and cold water line pressures for the purpose of minimizing mixed water temperature variations due to pressure fluctuations from the supply side. These devices shall have the capability to significantly reduce the outlet flow in the event of a cold or hot water supply failure.
Size Range
Sizes covered by this standard are 3/8" to 1" NPS (10 mm to 25 mm DN).
Flow Rate
Devices shall be capable of discharging the minimum flow rates indicated in Table 1 with a pressure drop of 20 psi (138 kPa).
Pressure Range
The device shall be designed for an operating pressure of 20 psi to 125 psi (138 kPa to 862 kPa).
Temperature Range
The device shall be designed to function with a water temperature range of 39 °F to 180 °F (3.9 °C to 82.2 °C).
Connections
Pipe threads and other connections shall conform to the applicable standards.
• Tapered pipe threads shall comply with ASME B1.20.1.
• Dry seal pipe threads shall comply with ASME B1.20.3.
• Compression assemblies shall comply with SAE J 512.
• Soldered connections shall comply with ASME B16.18 or ASME B16.22.
• Push fit connections shall comply with ASSE 1061.
• Press connections shall comply with ASME B16.51.
