The iStop antifreeze valve allows the circuit medium to be drained when the temperature reaches an average of 3˚C. This prevents ice forming in the circuit of a system, generally with a heat pump, avoiding potential damage to equipment, valves and pipework. The valves are suitable for a variety of fittings and pipes connected by a union.
