Valve Pressure Balancing

A pressure balancing valve is a type of anti-scald valve that is used in domestic hot and cold water systems. Its function is to ensure correct water delivery temperature despite changes in water supply pressure. Typically, this valve prevents a surge in hot water when the pressure in the cold water supply drops, but it can also prevent the water from suddenly turning cold due to a large hot water demand such as a washing machine. For new construction, many states have code requiring the installation of pressure balancing valves.

Pressure balancing valves are most commonly found in bath and shower plumbing at the junction of the hot and cold water supply. Often times they are incorporated into the fixture handle. They work by opening and closing inlet ports using small pistons. Some valves have a diaphragm for a smoother transition through the temperature range. An adjustable high limit stop is available with many pressure reducing valves for added safety and control.
