Eaton/Dole Freeze Protection Valves
Eaton Dole Model FP-35 or FP-45
Freeze protection bleed valve utilizes a temperature activated element which does not require any external source of power. The valve opens at 38°, or 43 1/2°F ( depending on model number) allowing the discharge of near freezing water which is replaced by warmer water. When this warmer water reaches the valve, the port closes. This cycle repeats as often as necessary. The amount of water dispensed depends mainly on ambient air temperature, make up water temperature, the duration of the cold spell and the number and size of collectors. The system is functioning properly when water is being discharged from the valve during near freezing conditions. For water to be discharged at the time of operation, system water pressure must be maintained. High temperature plastic body, 1/2" brass male threaded connection. 5/8"ID anti-siphon discharge port, 150 PSI maximum operating pressure.
