SAX Valve Actuator
24 Vac, Floating or Proportional Control
Floating, 0 to 10 Vdc or 4 to 20 mA
Non-Spring Return
Flowrite Globe
Flowrite SAX Valve Actuator.
Description
Designed for use with Flowrite valves with a 3/4-inch
(20 mm) stroke. The Flowrite SAX Electronic Actuator
requires either a 24 Vac or 24 Vdc supply, and receives a
0 to 10 Vdc or 4 to 20 mA control signal to proportionally
control the valve or a oating control signal to provide
oating control of the valve.
Features
• Proportional or oating (3P) control
• Direct-coupled installation
• Visual and electronic stroke indication
• Manual override
• Non-spring return
• 180 lb. (800 N) nominal force
• Automatic calibration (SAX61.03U only)
• Electro-mechanical switches protect components from
overload and stall condition
• Maintenance-free
Applications
The Flowrite SAX Electronic Valve Actuator is designed
to be used with the Flowrite and other valves in liquid
and low pressure steam service applications. They are
ideal for installations requiring quick response and
excellent resolution.
