Description
AVG Solar Hot Water Frost Protection Valve FPV-15
The Frost Protection Valve (FPV) has been developed to meet the requirements of thermosiphon solar collector panels installed in a frost prone environment.
Important note:
- The AVG Frost Protection Valve (FPV) is not recommended for freeze zones. A closed circuit collector panel with an approved anti-freeze fluid transfer should be used for these locations.
OPERATION
The Frost Protection Valve is designed to protect a solar collector panel from frost damage when the outside air temperature drops. The air temperature is monitored by a sensitive wax filled element which reacts by opening the FPV valve seat when the temperature drops. This allows warm water from the solar storage cylinder to flow through the solar collector panel and out of the FPV. The warm water flowing through the solar collector makes it harder for the panel to spot freeze which could damage the solar collector. The warm water flowing through the FPV will eventually close the valve seat and the water will stop fl owing. The FPV will automatically repeat this cycle until the outside air temperatures rise.
INSTALLATION
It is important to refer to the solar water heater manufacturer’s installation instructions in conjunction with the following instructions. AVG recommend that an Frost Protection Valve be installed onto each solar collector panel within the solar collector array to ensure the best protection. There may be some differences between the connection fi ttings to the solar collectors from each manufacturer so you may require a special adaptor to fi t the Frost Protection Valve. The AVG frost protection valve requires a 15mm ( ½” ) male fi tting to connect to.
MAINTENANCE
The frost protection valve has small water ways and may be prone to a build up of sludge when installed at the lower connection fitting of a solar collector. AVG recommends checking and cleaning at regular intervals to prevent valve malfunction and possible damage to the solar collector panel.

Ordered the item online arrived a day later.
Very satisfied it came with two washers. Attaching it to the solar heater panel was a few seconds job. The same valve I had lasted 4 years. Hope this lasts too.
