Description
The Caleffi 502630 ROBOCAL Automatic Air Vent Valve removes trapped air from hydronic circuits to prevent air pockets that may interrupt water circulation. Constructed with a brass body and 3/8-inch male connection, this component releases accumulated air automatically through an internal float mechanism as fluid moves through the line. In HVAC systems involving boilers, heating loops, and chilled water assemblies, it connects to piping sections requiring continuous air elimination. Its operation contributes to quieter circulation, and improved fluid movement during ongoing system activity.
