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.
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.
