lntroduction

Application Details

The Y20EBD Valve Linkage converts the rotary motion of an M100 Series Motor Actuator to a linear movement in order to operate several types of valves.

A rack and pinion drive mechanism provides the linear movement. The rack assembly contains a spring that, when compressed by over travel, will maintain valve close off to rated values. The pinion gear may be reversed for manual operation with a 3/8 inch socket drive extension for service of controlled equipment.

Note: The Y20EBD linkage kit can be used on Barber-Colman

1-1/2 to 2 inch valves. Use the grooved adapter bushing provided with the linkage kit for V-90 Series and the mid-bracket position. Larger Barber-Colman valves can mount onto the Y20EBD yoke directly; however, adding locally purchased large washers under the linkage bracket to prevent paint damage is recommended.

A selection of models are available to adapt M100 Motor Actuators to several types of valves.

A Y20EBD-4 linkage is available to enable an M150 Motor Actuator to operate S91 auxiliary switches for automatic heating/cooling changeover applications. The Y20EBD-4 allows additional over travel after valve close off for switch operation. See Y20 Series Linkage Kits Product Bulletin for a complete description.

Y20EBA valve linkage kits are available to adapt the M100 Series Actuators to valves made by other manufacturers. See Y20 Series Linkage Kits Product Bulletin for more information.

Refer to the technical bulletin provided with the motor actuator for information on wiring the motor actuator and related adjustments.

Installation Overview

Upright mounting of the motor actuator is recommended. When valve mounting, do not mount below the horizontal plane of the

valve piping to prevent damage to the motor actuator if the valve leaks or develops condensation.

Do not install the motor actuator in atmospheres with explosive vapors or escaping gases, or where vapors having deteriorating properties might attack the actuator’s metal parts.

Do not install where the ambient temperature of the surrounding area falls below -40°F (-40°C) for non-spring return motor actuators, or

-35°F (-37°C) for spring return motor actuators. The maximum ambient temperature of the surrounding area of the motor actuator should not exceed 125°F (52°C).

Valve medium temperatures above 250°F (121°C) are permissible only if the maximum ambient temperature at the motor actuator is less than 105°F (41°C).

Use insulating washers furnished with the linkage kit for valve medium temperature applications over 250°F (121°C).

Locate the motor actuator where the shaft and wiring terminals are accessible.

The non-spring return M100 Actuator will hold its position if power is removed. The spring return actuator will return to its zero position if power is removed. Both types will hold their current position if the control signal is satisfied.

Note: The spring return is intended only as a safety feature to drive the

actuator to its zero position in the event power is interrupted or turned off.

There are three sections to the installation of the Y20EBD valve linkage kit:

1. Configure and mount the yoke on the valve.

2. Mount the actuator and linkage assembly to the yoke and connect to the valve.

3. Adjust the travel limits to actuate the over travel spring and seat the valve.

Configuration and Mounting

Valve Lift

The information obtained in the following steps will be used for the travel adjustments later. The reason that these measurements are here is that it is easier to take the measurements prior to installing the linkage and actuator than after.

For valves with various lift requirements, the actuator will require a change in travel by 15° for each additional 0.1 inch (2.54 mm) of lift required.

To determine the lift required:

Valve Stem

Full Down

Valve Stem

Full Up

Figure 2: Stem Travel Measurement

1. Measure the valve stem length in the full down position as shown in Figure 2.

2. Measure the valve stem length in the full up position as shown in Figure 2.

3. Subtract the full down position from the full up position, this will provide the valve lift.

4. Divide the valve lift by 0.1 inch.

5. Multiply the result by 15°.

6. Provide additional 15° rotation on 2-way valves and 30° additional rotation on 3-way valves for over travel seating.

Note: Maximum actuator rotation is 270°, which allows up to 1.7 inches

lift on 2-way valves and 1.6 inches lift on 3-way valves.

Note: VT valves have only 5/16 inch lift which requires a reduction of

actuator travel by 25° from factory setting.

Record the value for use with the travel adjustments.
