Freeze Protection Valves

A thermostatic element senses water temperature in the valve. If the temperature falls below 35ºF, the valve will modulate open allowing water to drain from the system. The valve will remain open as long as the water flowing by the sensing element is less than 40ºF. When the water temperature rises above 40ºF, the valve will close.

  • Corrosion resistant stainless steel body
  • Long service life
  • Narrow temperature band
  • System pressures will not affect opening temperature
