The valve should be securely held in place by banding or other means of support to prevent accidental

damage due to movement of the valve.

For outdoor storage, special crating and valve preparation can be provided, at an additional charge,

based upon specific requirements for each situation. Periodical checks at least every 6 months have to

be carried out in the storage area to verify that the above mentioned conditions are maintained.

Handling:

Most valves are supplied with a removable lifting eye. Always lift the valve using this device, as damage

to the valve body or threads (if applicable) could occur from improper lifting. Alignment and final

installation should be done while the valve is being supported by the lifting eye.

The valve should never be used as an alignment point in the pipeline. Be sure the pipeline flanges on

both sides of the valve are aligned with the proper spacing before the valve is installed into the system.

Never lift or move the valve assembly by using the body rim, external springs or levers (if supplied),

valve disc or mounting holes.

Transport, unpack and store being careful not to scratch the surfaces of flanges or gaskets. Also, take

steps that will prevent any foreign matter from getting into the valves. Wooden plate or plastic caps

should not be removed until the valves are installed.

The transportation of all packed material must be carried out safely and following the local safety

regulations.

INSTALLATION

1. Remove the valve from carton or packing skid.

2. The protective rust proof coating on the internal parts of steel or cast iron valves should be removed

by brushing out with any standard petroleum solvent (Varsol, Kerosene) and air dried. Insure

internal parts operate freely.

3. Stainless Steel or Bronze valves need only to be wiped clean and installed.

4. In horizontal flow installation, the hinge shaft must be horizontal.

5. Insert the valve between two companion flanges of the same series as the valve and place gaskets

on flange faces. The arrow on the valve or name plate indicating direction of flow should coincide

with line flow. Install studs through companion flanges and tighten, using standard industry

practice.

6. We recommend valve be installed at least five (5) pipe diameters downstream from a pump

discharge and/or other pipe fittings for maximum service life.
