AT33A000 Modulating PopTop valve actuator Non-Spring Return 24 Vac Three Wire Floating
The TAC Erie™ Modulating PopTop™ Series valve actuator assemblies are designed for closed hydronic heating and cooling systems. The Modulating PopTop is used to control fluid flow in fan coil units, VAV reheat, unit ventilators, AHUs and radiant applications.
The Modulating PopTop Proportional (P) type is compatible with any 0 to 10 Vdc or 4 to 20 mA signal with jumper selectable operating range and action resulting in precise positioning. The floating (T) type is compatible with any 24 Vac three-wire signal when three minute time-out logic resides in the valve actuator or system controller.
The Modulating PopTop valve assemblies allow the actuator to be snapped onto, or off from, the valve body. The actuator can be mounted after the valve body has been installed into the system without the need for linkages or calibration.
Available in standard (non-spring return) and spring return modulating actuators. The two-way spring return
modulating actuators are provided in either normally open or normally closed operation. The three-way valves are available in normally closed operation only. Valve body reversal provides normally open flow for three-way valve bodies.
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 the valve body
Three wire floating and 0 to 10 Vdc or 4 to 20 mA proportional available
Spring return will return actuator to normal position when the power is lost for more than two minutes.
