TRANSPORTATION AND STORAGE

Check the valve and the accompanying devices for any

damage that may have occurred during transport.

Store the valve carefully. Storage indoors in a dry place is

recommended.

Do not remove the flow port protectors until installing the

valve.

Move the valve to its intended location just before instal-

lation.

The valve is usually delivered in the closed position.

3 INSTALLATION

3 .1 General

Remove the flow port protectors and check that the valve is

clean inside. Clean valve if necessary.

Flush the pipeline carefully before installing the valve.

Foreign objects, such as sand or pieces of welding elec-

trodes, will damage the ball and seats.

3 .2

Installing in the pipeline

WARNING:

THE VALVE SHOULD BE TIGHTENED BETWEEN FLANGES USING
APPROPRIATE GASKETS AND FASTENERS COMPATIBLE WITH THE
APPLICATION, AND IN COMPLIANCE WITH APPLICABLE PIPING
CODES AND STANDARDS. CENTER THE FLANGE GASKETS CARE-
FULLY WHEN FITTING THE VALVE BETWEEN FLANGES. DO NOT
ATTEMPT TO CORRECT PIPELINE MISALIGNMENT BY MEANS OF
FLANGE BOLTING!

The valve may be installed in any position and offers tight-

ness in both directions. It is recommended, however, that

the valve be installed with the insert facing upstream. It

is not recommended to install the valve with the stem on

the underneath side because dirt in the pipeline may then

enter the body cavity and potentially damage the stem

packing (see Figure 3).

Figure 3 Avoid this mounting position

Refer to the Section 4, MAINTENANCE for stem seal

adjustment. If there is weepage past the stem seals upon

installation, it means the valve may have been subject to

wide temperature variations in shipment. Leak-tight per-

formance will be restored by a simple stem seal adjustment

described in the MAINTENANCE section.

3 .3

Valve Insulation

Jamesbury

Flanged Ball Valves do not require insulation. If

desired, the valve may be insulated; however, the insula-

tion must not continue above the upper level of the valve.

(see Figure 4).

Figure 4 Insulation of the Valve

3 .4 Actuator

WARNING:

WHEN INSTALLING THE ACTUATOR ON THE VALVE, MAKE SURE
THAT THE VALVE ASSEMBLY FUNCTIONS PROPERLY. INFORMATION
ON ACTUATOR INSTALLATION IS GIVEN IN SECTION 7 OR IN THE
SEPARATE ACTUATOR INSTRUCTIONS.

The actuator should be installed in a manner that allows

plenty of room for its removal.

The upright position is recommended for the actuator.

The actuator must not touch the pipeline, because pipeline

vibration may interfere with its operation.

In certain cases it may be considered advantageous to

provide additional support to the actuator. These cases
