Description
Thermic Actuators require a 24 Vac/Vdc control signal to provide
two-position, NO or NC control. This actuator is designed to work
with Zone Valves with a 1/10-inch (2.5 mm) stroke.
Features
• Direct-coupled — install without tools
• Movement and position indication
• Robust, no maintenance required
• Friction-free
• Two-wire connection
• Standard versions with 3.9 foot connecting cable
• PWM control
• AC/DC two-position control
Applications
Thermic Actuators are for use with 1/10-inch (2.5 mm) stroke
Zone Valves.
