WARNING

For Safety reasons, it is important to take the following precautions
before working on the valve:
1. Klein Slurry Valves are not to be used as an end of line
service valve.
2. Ensure that the procedures below meet or agree with the
site procedures if not review with your site safety officers.
3. Personnel making any adjustments to the valve should
utilise equipment and clothing normally used to work with
the process where the valve is to be installed.
4. The line must be depressurised, drained and vented
before installing or working on the valve.
5. Handling & installation of all valves, operators and
actuators must be carried out by personnel trained in all
aspects of installation and manual/mechanical handling
techniques using site occupational health and safety
procedures.
6. Ensure the valve pressure/temperature limitations
marked on the nameplate are above or equal to the
service conditions.

Storage Instructions

The valves discs, seats, stems and end connections should be
adequately protected against damage. The protective end covers
should not be removed until ready for installation.
For long term storage of Klein valves the manufacturer would
recommend the following procedures be adopted:

Protection

The internals of valve are to be sprayed with a moisture
exclusion/corrosion inhibitor material. To achieve this, wearing
the correct protection equipment and dress, remove inlet end
covers and open valve by rotating wrench and direct the
atomized spray mist into the open valve cavity. Spray around
seat and disc and close valve. Spray onto stem and yoke
bush. Reseal the end covers.

Operation

Valves to be cycled every three months. The cycle operation
should be to the full open then to the full closed position.

Storage

All valves should be stored in the fully closed position End
protection caps or covers should remain on the valve at all
times.

General

The preferred direction of flow for K4050, K4100 and K4150 Klein
valves is from the lower port below the disc, exiting from the side
port. Gaskets are required to fit between valve flanges and pipeline.
Check gaskets are suitable for duty.

Line Installation

Caution should be exercised to prevent damage of the valve sealing
mechanism during installation. The following steps will assist in
complying with the correct installation procedure.
Remove the protective end covers prior to installation. The gasket
faces should be wiped with clean solvent to ensure gasket faces
are clean.
Substantial supports should be provided for the free ends of the
pipeline and for the valve during installation. Unsupported pipelines
hung from valves can cause high stress in valve body leading to
possible damage.
For K4100 valves where the mating component has been removed
from the remainder of the valve, the disc should be in the closed
position before refitting to the installed mating component. This will
allow the disc to hold the seat in the correct position to ensure the
valve will seal after refitting the mating component.
Where possible, leave valve in `open’ position until entire
construction work has been completed, pipeline cleaned and plant
is ready for start up.

Testing Installations

When pipeline or vessel installations are being tested it is desirable
to have all Valves in the `open’ position. DO NOT USE Klein Valves
as Block Valves when testing pipelines or vessels as foreign matter
may seriously damage sealing mechanism. Should valves be used
for such testing, the Manufacturer takes NO RESPONSIBILITY for
any damage which may affect the valves sealing mechanism and all
Guarantees are withdrawn. If the user decides to test such
installations with the valves `closed’, caution should be exercised to
ensure that the sealing mechanism is not subjected to pressure
differentials in excess of the maximum operating pressure of the
valve seat design.
