The Erie™ Modulating PopT op™ 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.

Figure-6 Mounting.

Figure-7 Two-Way Spring Return Valves.

The Modulating PopT op 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.

Piping

Refer to the piping diagrams in Figure-7 fo r two-way valves. For three-way valves refer to Figure-8.

• The 3-way is only configured as normally closed. For normally open configuration to the

coil turn valve around. For proportional valves, set the control action (direct or reverse accordingly).

WARNING:

• The valve should be used in a closed loop system.

• All valves must be piped so that the plug closes against the direction of flow. For two-way

valves, flow is from port B to port A. For normally closed three-way valves, B is the service port and A is the bypass port. For normally open three-way valves. A is the service port and B is the bypass port.

• Three-way VM valves must be piped in a mixing configuration, not diverting.

1. 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.

CAUTION:

• The plug inside the valve is made of a plastic material. It may be damaged by heat con-

ducted through the valve body if it remains seated against its port during soldering. Be sure to manually open the valve before soldering to prevent damage.

• If the manual operating lever does not move freely for manual positioning, the solenoid

may have latched during shipping. Do not force the lever. Instead, first unlatch the solenoid by placing the red manual solenoid latch lever (on the side of the actuato r ) in the "Up" position, then placing the manual o perating lever in the middle position.

2. With the valve in the mid-position, latch the solenoid by placing the manual solenoid latch lever in the "Up" position. Then, detach the actuator by depressing the release button and pulling it away from the valve body (Figure-9).

CAUTION:

• Be sure to remove the actuator from the valve body before soldering, to avoid damage to

the actuator and to ease the soldering process.

• Use only lead or tin based solder with a melting point below 600×F (315×C).

4. Solder the valve body in place, directing the flame tip away from the valve and taking

N O T E

care not to overheat the joint area. When finished, cool the valve quickly with a wet cloth.

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."

NPT and Rp Threaded Valves

When installing threaded valves, the actuator should be detached from the valve body to ease installation. To do so, first slowly move the actuator’s manual operating lever (on the front of the actuator) to the middle position. Then latch the solenoid by placing the red manual solenoid latch lever on the side of the actuator to the "Up" position. Finally detach the actuator by depressing the release button and pulling the actuator away from the valve body (Figure-9).

1. Apply teflon tape to all but the last two threads on the end of a properly threaded, reamed, and cleaned pipe. Make sure that pipe chips, scale, etc. do not get into the pipe since this material may lodge in the valve seat and prevent proper closing and opening of the valve.

2. Start the joint by hand-screwing the pipe to the valve. If the thread engages normally, turn the pipe by hand as far as it will go.

3. Use a wrench to fully tighten the valve to the pipe using the flats located on the valve body ports. Take care not to over-tighten or strip the threads.

4. Reinstall the actuator according to "Reattaching the Actuator to the Valve Body."

Reattaching the Actuator to the Valve Body

1. Before reinstalling the actuator, be sure that its manual operating lever is in the midposition, and that the solenoid is latched. The solenoid is latched when the manual solenoid latch lever is in its "Up" po si ti on (Figure-9).

2. Depress the release button.

3. Align the valve body with the actuator to ensure the stem is inserted into the large mating hole on the bottom side of the actuator (Figure-9).

4. Engage the actuator on the body and release the button.

Wiring

• Multiple actuators may be connected to a single controller, up to the current rating of the

controller and transformer. Do not exceed the maximum current draw of the controller.

• Use of a properly sized, inherently limited, Class 2 transformer is recommended.

• Use only 18 to 24 AWG copper wire for all connections.

• The return spring feature is primarily a safety feature. It is recommended that the spring

return feature is not used for routine, normal operation.

Three-wire Floating

• The three-wire floating spring return valve includes a time-out feature that automatically

turns off the control signal to the valve after a pre-determined period of continuous operation. This time period is three minutes at 60 Hz and 3.6 minutes at 50 Hz.

• Spring return valves feature a two second time delay upon power loss, to prevent the loss

of valve position during brief outages. There is a three second delay at power-up.

1. Remove the cover from the actuator, then connect the power and control wiring to the terminal block (Figure-1 and Figure-3).

2. Reinstall the cover onto the actuator.

Page 10

N O T E

INITIAL SETUP Application Notes

Proportional

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).

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. To change the action to reverse-action (valve closes with an increase in control signal), simply remove the action jumper J2 and relocate it to the reverse-acting pins. See Figure-4 and Figure-5.

2. Reinstall the cover onto the actuator.

These valves are designed for application to closed hydronic heating and cooling systems. Use in systems which have substantial make-up water (open systems) is not recommended. High levels of dissolved oxygen, chlorine, and debris that may be found in open systems can attack the valve materials and result in premature failure.

3-Wire Floating "T" Type

The controller or thermostat used to operate the "T" type must be configured to turn off the control signal after being on continuously for three minutes.

3-Wire Floating Time Out "T" Option

If the control system used does not have the ability to limit the running time, then the time out option must be utilized, which automatically cuts off the control signal to the valve after three minutes of continuous operation. This is standard on the spring return, and is an option on the non-spring return.

Proportional "P" Type

Multiple "P" valves may be connected to a single controlle r, up to the current rating of the controller and transformer. For 4-20 mA control, a separate isolation transformer must be used with each valve. The actuator is also provided with a jumper to allow the action to be reversed. All units are shipped with the actuator in the DA (direct acting) mode, which means that the valve opens the B port upon receiving an increasing control signal. To change the action to reverse action (valve closes upon receiving an increasing control signal), simply remove the action jumper and relocate it to the RA (reverse acting) pins.

CHECKOUT

1. Make sure the valve operates freely before installing the valve.

2. If the stem does not operate freely it may indicate that the stem was damaged and may require that the valve be repaired or replaced.

3. After the piping is under pressure check the valve body and the connections for leaks.

4. After the valve and actuators are installed power the actuator and check the operation. a. For two-way model:

Power the valve to the close position (per label), and the "B" port should be closed.

b. For three-way model:

Power the valve to the open position (per label), and the "A" port should be closed.

c. For Spring Return model:

Removing power should return the actuator to its normal position.

DIMENSIONAL DATA

The PopT op 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 PopT op Series modulating valves, when powered, the actuator moves to the desired position, at the same time tensing the spring return system. When power is removed for more than two minutes the spring returns the actuator to the normal position.

The Modulating PopTop Series valves require no maintenance. Replace defective modules Regular maintenance of the total system is recomended to assure sustained, optimum

performance.

Replace any damaged or failed components with complete bodies or actuator replacements.
