3 Position Actuator for Stations
Applications
The Three Position Actuator for Stations is designed
to provide floating action control of Viega Mixing
Stations, Enhanced Mixing Stations and diverting
valves. The actuator is used in electronic temperature
control systems which use hot and/or cold water as
the controlled medium in radiant heating systems,
snowmelting, or other temperature mixing applications.
The actuator is designed for operation by any 24V
floating signal controller such as the Basic Heating
Control.
Features
• Small size allows installation where space is limited
• Maintenance free actuator in plastic housing
• Synchronous motor
• Magnetic coupling for torque limitation independent
of voltage
• Suitable for 3-position modulating control (floating)
without proportional feedback
• No tools required for mounting
