Application

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.

Features

• 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.

INSTALLATION Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately. If undamaged, open the package and inspect the device for obvious damage. Return damaged products.
PAGE 7
Mounting The Modulating PopTop Series valves can be mounted in horizontal or vertical piping. When installed in horizontal piping, the actuator must be above the valve body. Refer to Figure-6. 360 85 Figure-6 Mounting. Piping Refer to the piping diagrams in Figure-7 for two-way valves. For three-way valves refer to Figure-8. NOTE The 3-way is only configured as normally closed. For normally open configuration to the coil turn valve around.

Slowly position the actuator’s manual operating lever (on the front of the actuator) to the middle position, to manually open the valve so that the plug is not in contact with the valve body.

4. Solder the valve body in place, directing the flame tip away from the valve and taking care not to overheat the joint area. When finished, cool the valve quickly with a wet cloth. NOTE The valve body may be submerged in water, or pressurized, for leak testing before reattaching the actuator. 5. Reinstall the actuator according to "Reattaching the Actuator to the Valve Body.

Proportional NOTE If multiple proportional valves are used on a single 4 to 20 mA loop, each valve must have its own isolation transformer. 1. Remove the cover from the actuator, then connect the power and control wiring to the terminal block (Figure-4 and Figure-5). NOTE All units are shipped with the actuator in the direct-acting, 0 to 10 Vdc mode, which means that the valve opens the B port upon receiving an increasing Vdc control signal.

THEORY OF OPERATION The PopTop Series floating or proportional modulation valves are modulating valve actuator assemblies. The modulating valves are designed to control the flow in the circuit by making incremental adjustments to the flow path with-in the valve. The Spring Return PopTop Series modulating valves, when powered, the actuator moves to the desired position, at the same time tensing the spring return system.
