Mixing Valves

Thermostatic and Rotory Mixing Valves for Heating and Potable Water Plumbing | Pexheat.com

Mixing valves alow for control of water temperature to heating zones. Radiant floor heating systems are very susceptible to heaitng problems due to water temperature. Overheating - temperature swings, Underheating, wood flooring shrikage, carpet fiber break dow, etc. Therefore, addition of a mixing contol to a radiant floor system will signigicantly protect your investment.

Mixing valves come in three packages.

  1. Manual Set - rotary valves
    • Rotate the valve till you get the right temperature and remove the handle to prevent tampering.
    • Does not compensate for changes in supply water temperature of increase in load.
  2. Thermostatic Mixing Valves
    • Adjusts the valve to maintain output water temperature due to changing supply water temperature. (Anti-scale valve)
    • Does not compensate for increase in load.
  3. Motorized - rotary valves.
    • Motorized valves are connected to a control with sensors. The control will sense supply water temperature, load temperature, boiler return water temperature.
    • The control can adjust the valve to protect the boiler from low return water temperatures or heating zone from increased boiler temperatures.
    • The control can allow hotter or cooler water to the zones for load changes due to weather (outdoor reset).
