SKD62UA Series Electronic Valve Actuator, 
Advanced Features 

 

 

Product Description 

The SKD62UA electronic valve actuator requires a 24 
Vac supply and receives a 0 to 10 Vdc or 4 to 20 mA 
control signal to proportionally control a valve. These 
actuators are designed to work with the Flowrite™ 
VF599 series valves, or other manufacturer's valves 
with fitted with the appropriate Universal Valve Retrofit 
Kit.
