The IC2 control valve aims to meet the demands of extremely low-temperature environments, operating at temperatures as low as -452 degrees Fahrenheit (-269 degrees Celsius).

The control valve is rated for the CL600 pressure class, and is available in line sizes from 1 to 4 inches (DN25 to DN100), with more options forthcoming.
Explore how refrigerant chemistry, heavier-than-air gases, and real-world brazing hazards highlight critical safety practices for HVAC and mechanical contractor.
We become comfortable with what we perceive to be best practices and believe they are also safe for all involved. Cupric oxide will always be a concern when brazing copper refrigerant line sets, so purging with nitrogen is the best way to keep your refrigerant lines clean and pristine during brazing.
In a here-we-go-again move, we must now transition from HFC to A2L mildly flammable refrigerants. The good news is the operating pressures are virtually the same and this time, the refrigerant oil is the same.
