Silicon valve supports heating and cooling operations
The Very High Capacity Modular Silicon Expansion Valve expansion valve (VHC-MSEV; photo) is available for the 25–50-ton heating, ventilation and air conditioning (HVAC) and refrigeration market. This family of valves expands the cooling capacity range of the MSEV product line from the existing 1–25-ton range to 25–50 tons. This valve package has a pre-set library of refrigerants, including A2L refrigerants, within its controller, and it can be adapted to new or application-specific refrigerants. This, combined with its modular design, allows it to support various applications at different cooling capacities within a single footprint, says the company. — DunAn Microstaq, Austin, Tex.
