The Flowrite SKD Valve Actuator is used with Flowrite and other standard valves with a 3/4-inch stroke. This electronic valve actuator requires a 24 Vac supply to provide a 0 to 10 Vdc or 4 to 20 mA proportional control signal to the valve. Normally closed and 3-way upper port nominal force is 225 lb-in (1000N); normally open and 3-way bypass port is 258 lb-in (1150N). Other features of this valve actuator include automatic stroke calibration, manual override, die-cast aluminum housing, and spring return functionality.
Additional info SKD..U, SKD..UA are UL listed. Control devices MK..5.. are control devices with safety shut-off function per DIN EN 14597.
