Erie™ Spring Return Floating & Proportional Actuators
Model Chart
Specifications
The AP series proportional and AT series floating
PopTop™ actuators incorporate equal percentage flow
characteristics. The floating and proportional
actuators are designed to be used on the 1/2 to 1-
1/4 in. VM series valves for precise temperature control
of fluid flow in heating or cooling applications. See
valve section for details.
Features:
• Floating model is compatible with any 24 Vac three-wire signal.
• Proportional model compatible with any 0 to 10 Vdc or 4 to 20
mA controller.
• Spring return logic is only for emergency power loss.
• Microprocessor controlled (proportional only).
• Magnetic clutch to maximize the life of the motor and gear train.
• Manual operating lever/position indicator facilitates field setup.
• Easy to use lever terminal blocks.
• Returns actuator to normal position when power is lost for more
than 2 seconds.
• Actuator can be installed after valve body.
• Refer to F-27384, Invensys Valve Catalog for compatible 1/2 to
1-1/4 in.c VM Series two or three way zone valves.
