Watts F256661 Valve 319848-301 the 4J sleeve coupling flangeThe Watts F256661 140S 3 150 210 FS is a freeze stat temperature limit control used in HVAC systems to protect coils, heat exchangers, and air handling equipment from low temperature damage. It functions by monitoring temperature and initiating a control response when conditions approach unsafe levels, helping prevent coil freeze up and system failure. In the field, this type of control is commonly used in air handlers, hydronic coil assemblies, and
