SKD6xU Electronic Valve
Actuators
24 Vac Proportional Control
Siemens Industry, Inc.
Description
The Flowrite 599 Series SKD6xU Electronic Valve Actuators require a 24 Vac supply
and receive a 0 to 10 Vdc or a 4 to 20 mA control signal to proportionally control a
valve. These actuators are designed to work with Flowrite 599 Series 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 or non-spring return fail-in-place
• Automatic stroke calibration
• Maintenance-free
Application
These electronic actuators are designed to be used with Flowrite 599 Series valves and
Siemens Industry standard valves with a 3/4-inch (20 mm) stroke in liquid service
applications.
CAUTION:
Do not use in low pressure steam applications.
Product Number
