Modulating Refrigerant Valves with Magnetic Actuator MVL661

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).
