Advanced Features
Description
Features
Application
The Flowrite 599 Series SKB/C/D62UA Electronic Valve Actuator requires a 24 Vac
supply and receives a 0 to 10 Vdc or a 4 to 20 mA control signal to proportionally control
a valve. This actuator is designed to work with valves with a 3/4-inch (20 mm) or 1-1/2-
inch (40 mm) stroke.
Direct-coupled installation requires no special tools or adjustments
Visual and electronic stroke indication
Die-cast aluminum housing
Manual override
Spring return to fail-safe position
Automatic stroke calibration
Direct or reverse acting
Adjustable start and span
Stroke limit control
Choice of linear or equal-percentage flow characteristic
Maintenance-free
These electronic actuators are designed to be used with Flowrite 599 Series valves with
either 3/4-inch (20 mm) stroke (SKB/D) or a 1-1/2 inch (40 mm) stroke (SKC) in liquid
and steam service applications; or other manufacturer's valves with appropriate
Universal Valve Linkage Kits.
