Required Components

Selecting the valve assembly number from Table-1 specifies a complete assembly of an actuator, valve body, and the AV-401 linkage kit. If no valve assembly number is available the actuator, valve body, and AV-401 listed in

Ta bl e -1 must be purchased separately.

INSTALLATION

Inspection

Requirements

Mounting

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 any damaged products.

• Tools (not provided):

Appropriate hand tools for field service.

• Training:

Installer must be a qualified, experienced technician

• Avoid locations where excessive moisture, corrosive fumes, or vibration are present. Do

not insulate above actuator mounting nut trapping moisture.

• Install all two-way valves so that they close against the flow. An arrow on the valve body or

a tag indicates the proper flow direction.

• Install all three-way mixing valves with two inlets and one outlet.

• Install all three-way diverting valves with one inlet and two outlets.

• Do not install the actuator below the center line of the valve. For steam applications only,

mount the actuator above the valve body at 45° from vertical.

1. Actuators can be mounted in any upright position above the centerline of a valve body.

2. When selecting a location, allow sufficient room for accessories and for service of the product.

3. Maintain proper flow direction when installing all globe and radiator-type valves. Flow direction is indicated by an arrow on the valve body or by information on the attached tag.

For current valves refer to Table-1 to maintain the proper stem height during assembly. For obsolete valves see Ta bl e - 1 or Ta b l e- 3 .

1. Thread the locknut and the stem extension several turns onto the valve stem (Figure-1).

Figure-1 Assembly of AV-401 Linkage Kit onto Valve.

2. Push or pull the valve stem to the position (stem up or stem down) noted in Ta bl e -1 ,Ta b le - 1, or Ta b le -3 .

3. Adjust the height of the stem extension as indicated in Ta b le - 1 . This height (dimension “X”) is measured from the top surface of the packing nut to the center of the hole in the stem extension (

Figure-1).

4. Holding the stem extension stationary, tighten the locknut against it to secure it in position on the stem.

5. Install the actuator onto the valve by screwing the actuator base onto the mounting nut

Figure-2). The actuator may be rotated as desired to facilitate making the pneumatic

( connection.

6. Apply air pressure to the actuator so that the holes in the stem extension and the actuator stem are aligned. Insert the connecting pin into the aligned holes.

MAINTENANCE

FIELD REPAIR

The actuator linkage requires no maintenance.

Regular maintenance of the total system is recommended to assure sustained, optimum performance. Hard water leaves abrasive deposits and reduces component life. To maximize valve life consult EN-205, Water System Guidelines, F-26080.

Individual parts of the actuator linkage are not repairable. Replace an inoperative actuator linkage with a functional unit, or replace individual parts as necessary (Figure-3).
