Performance Requirements for Individual Pressure Balancing In-Line Valves for Individual Fixture Fittings
Automatic pressure balancing in-line valves are used to equalize incoming hot and cold water line pressures for minimizing mixed water temperature variations due to pressure fluctuations when used with a mixing valve or two handle valve set. They are not designed to limit the maximum outlet temperature at the point-of-use. The device is intended for use in individual plumbing fixtures fittings such as shower heads, bath utility faucets and sink and lavatory faucets.
