INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow

them could damage the product or cause a

hazardous condition.

2. Check ratings given in the product data literature

and on the product to ensure the product is suit-

able for your application.

3. Installer must be a trained, experienced, licensed

service technician.

4. After installation is complete, check out product

operation as provided in these instructions.

Preparation

CAUTION

Equipment Damage Hazard.

Foreign particles like dirt and metal chips can

damage the ball seals.

Clean upstream lines prior to installation.

CAUTION

Equipment Damage Hazard.

Improper chemicals can damage the valve.

Use neither aerosol products nor petroleum-

based lubricants.

1. Clean the lines upstream of particles larger than

1/16 in. diameter. Open valves fully. Flush entire

hydronic system of contaminants (welding slag,

solder, scale, metal chips, etc.) and chemically

treat water according to local conditions prior to

operation.

2. Proceed with installation once the system specifics

(expansion/contraction of the system and its

medium as well as operating pressures) are within

tolerances.

3. Eliminate air from system.

4. Two-way valves are marked to show flow direction.

IMPORTANT

Flow arrows must point in the direction of the

flow for proper operation.

NOTE: For three-way valve mounting, see Fig. 3

through 5.

5. Stem rotation:

a. For two-way valves:

(1) Clockwise to close.

(2) Counterclockwise to open.

b. For three-way valves:

(1) Clockwise to increase B to AB flow.

(2) Counterclockwise to increase A to AB flow.

6. Valve must be mounted with the actuator/bracket

above the valve body. Do not install the valve with

the stem below horizontal or upside down. (See

Fig. 1 and 2.)

Mechanical Installation

The valveshave female NPT pipe fittings and should be

sealed with an approved pipe sealant or tape. Take care

not to use excess pipe dope to avoid interfering with

operation of ball. Torque should not exceed 75 ft-lb.

See Fig. 8 and 9 for valve dimensions. Refer to actuator

literature for actuator dimensions.

Mounting Plate Adjustment

The Actuator Mounting Plate can be rotated to a different

position for installation in confined spaces. This is

accomplished as follows:

1. Remove the handle from the shaft and set it aside.

2. Remove the two screws that hold the stem

assembly to the mounting plate and set them aside.

3. Remove and set aside the stem assembly.

4. Remove and set aside the two screws that attach

the mounting plate to the valve.

5. ENSURE VALVE IS ISOLATED AND DEPRES-

SURIZED BEFORE PROCEEDING. Remove yel-

low pressure plate marked “HIGH PRESSURE”

from valve bonnet, rotate 90° or 180°, and re-install

screws using same holes in pressure plate and the

appropriate pair of tapped holes in the valve bonnet.

NOTE: Take note of the screw hole positions on

the valve. They limit the mounting plate

positions.

6. Rotate mounting plate around valve top to the

desired position.

IMPORTANT

Do not rotate the valve stem while the hold-down

ring is removed. This can change the common

port from AB to A.

7. Lower ring down to valve body and engage it in the

new position relative to the mounting plate.

8. Tighten screws to valve body securing the mounting

plate.

9. Reattach the stem assembly to the mounting plate.

10. If desired, replace the handle on the shaft.

NOTE: See Fig. 6 for valve exploded view.

IMPORTANT

After adjusting a three-way valve mounting plate,

take note whether the AB port or the A port is the

common port.

Electrical Installation

1. If necessary, remove actuator wiring cover.

2. Wire the actuator according to the appropriate

diagram provided with actuator or job specifica-

tions. For detailed actuator information, see Honey-

well literature:

OPERATION AND CHECKOUT

Once both the mechanical and electrical installations are

complete:

1. Cycle the actuator to verify that the direction of rota-

tion suits the control sequence.

2. If the rotation direction is incorrect:

a. For 2-position control actuators: Remount actu-

ator on the bracket.

b. For floating control actuators: Reverse two con-

trol signal wires (CW/CCW).

c. For analog control actuators either:

(1) Reposition reverse/direct acting switch, or

(2) Remount actuator on the bracket.

3. If the control scheme requires fail-safe operation,

ensure that, upon removal of power, the valve

rotates to the desired position.

4. Spring return actuators are factory-configured for

A-port normally-closed fail-safe operation. To

change this to normally-open, remove and reinstall

the actuator in the opposite orientation as follows:

(a) Loosen the shaft coupling bolt using a 10

mm wrench.

(b) Loosen all other mounting bolts connect-

ing the actuator to the mounting bracket,

and set aside.

shaft.

(d) Move the actuator shaft coupling to the

opposite side of the actuator, as displayed

in Figure 7.
