Use
The MVL661..-.. refrigerant valve is designed for modulating control of refrigerant
circuits including chillers and heat pumps. It can be used in expansion, hot-gas and
suction throttle applications as well as with all commonly used safety refrigerants (R22,
R134a, R227ea, R404A, R407C, R410A, etc.) and R744 (CO2).
