Actuators

Model Chart

Specifications

The AP series proportional and AT series floating

PopTop™ actuators are designed to work with 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 as long as 3 minute timeout logic resides in the

controller or on the valve.

• 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.

• Actuator can be installed after valve body.

• Refer to F-27384, TAC Valve Catalog, Zone Valve Section

for correct applications.
