The EVU solenoid valve fromDanfoss, Inc.(Baltimore) is suitable for liquid, suction, and hot gas applications using any fluorinated refrigerant. Rated liquid capacity is from 1.9 to 5.07 TR (R-22); suction from 0.16 to 0.42 TR (R-22); and hot gas from 0.35 to 0.94 TR (R-22). Connection sizes are 1/4, 3/8, and 1/2 in. One key feature is the servo piston principle which enables the valve to open against a relatively high differential pressure, up to 520 psig.
