The EVU solenoid valve from Danfoss, 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.
