Description

The Flowrite EA 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 Flowrite VF 599 Series valves

and Siemens Industry, Inc. standard valves with a 3/4-inch (20 mm) stroke.

Features

• 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

• Selectable operation direction (direct-acting/reverse acting)

• Choice of linear or equal-percentage flow characteristic

• Maintenance-free

Application

These electronic actuators are designed to be used with Flowrite VF 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 service and steam service applications; or other manufacturer's valves with

appropriate Universal Valve Linkage Kit.
