Schneider Electric AV-650 Data Sheet

APPLICATION

This General Instruction sheet provides the information necessary to field assemble AV-650 gear train actuator linkage to Honeywell V-501 1 two-way and V -5013 three-way (1/2 to 3") valve bodies, with a 1-3/8" bonnet.

SPECIFICATIONS

Minimum Actuator Torque Required: 50 lb.-in. (5.6 N-m).

Actuator must have 180° stroke.

Stem Force: 150 lb. (667 N). Close-Off pressure Ratings for Gear TrainActuatros: See Table 1.

PRE-INSTALLATION Inspection

Visually inspect the carton for damage. If damaged, notify the appropriate carrier immediately. If undamaged, open the carton and visually inspect the device for obvious defects. Return damaged or defective products.

Required Installation Items

• AV-650 linkage

• Actuator

• Valve body

• Tools:

Allen wrench Crescent wrench Screwdriver

INSTALLATION

Caution:

• Installer must be a qualified, experienced technician.

• Install all globe-type valves with pressure under seat. An

arrow on the valve body indicates the proper flow direction.

• Always install three-way mixing valves with two inlets

and one outlet.

• Always install three-way diverting valves with one inlet

and two outlets.

Assembly of Mounting Bracket to Valve Body (See Figure 1)

1. Place mounting bracket on valve body.

2. Tighten the three set screws in the base of the mounting bracket.

Bodies V-5011 & V-5013 (1/2 thru 3") with a 1-3/8" Bonnet.

Assembly of Stem Extension on Valve Stem & Actuator on Mounting Bracket (See Figure 1)

1. Thread stem lock nut and stem extension down fully on valve stem.

2. Place actuator on mounting bracket. Fasten actuator to mounting bracket with three 1/4-20 screws provided.

Caution: Do not tighten mounting screws.

3. Place nylon bushing on actuator shaft.

Cam Positioning for Control System Application

1. Determine actuator shaft position from Figure 2 (no power to actuator). If actuator shaft position (indicated by short tooth) is not in the 9:00 or 3:00 position, power the actuator until this is the case. The actuator shaft of spring retu rn and MC actuator will be in the 9:00 or 3:00 position with no power to the actuator .

2. Determine the cam position on the actuator shaft by referring to Figure 2 and Table 2 and considering the application. Actuators are normally shipped from the factory for direct acting heating applications. A call for heat will cause the valve to open. On system checkout or field assembly, the applications may vary.

3. Place the cam in plunger and slip on the actuator shaft.

Assuring Proper Close-Off of Valve

For normally open two-way valve assemblies, spring return actuators:

1. With actuator in its spring return position, the cam should be pointing up (refer to Figure 2 and Table 2).

2. Power actuator so that cam is now pointing down.

3. With valve stem down, screw stem extension into plunger until holes in stem extension and plunger line up.

4. Turn stem extension up two full turns.

5. Raise actuator until connecting pin can be inserted through plunger and stem extension holes.

6. Tighten actuator mounting screws.

7. Tighten lock nut against stem extension.
