Antifreeze Valve 1" Male to Female Swivel
The antifreeze valve is designed to automaticallydrain water from the circuit when the system
temperature falls to 3°C, helping to protect the
system from freezing.
PRODUCT DESCRIPTION
The antifreeze valve allows the circuit medium to be drained when its temperature reaches an average value of 3 °C. This prevents ice forming in the circuit of a system, generally with a heat pump, avoiding potential damage to the machine and to the pipes.
