Commissioning Of Disk Type Non-Return Valve - Pentair SUDMO P740 Operating Instructions Manual






The disk type non-return valves are to be commissioned exclusively by competent and trained commissioning per-
sonnel.

The operator of the disk type non-return valves must draw up operating instructions so that all the information
required for the commissioning of the valves is available to the operating personnel.

The operator of the disk type non-return valves must ensure that the required safety and limiting systems of the
fittings as described in the "limiting systems" chapter are continually functional and that they cannot be switched
off whilst operating or changed with respect to their intended use.

Commissioning of the disk type non-return valves includes

a wet test, including testing of the valve opening behavior

a pressure and sealing test

thorough cleaning of the valves, if they are earmarked for processing foodstuffs.

Wet test, opening behavior, pressure and sealing test:

Run cold water through the valves.
Opening of the disk type non-return valves must be possible in a secure fashion with a primary pressure of
0.1 bar.

Pressurize valves.
To do this, seal the media supply line filled entirely with cold water located downstream of the disk type non-
return valves with a suitable isolation valve and apply the test pressure upstream of the disk type non-return
valves.

Test sealing of fittings by visual check.

In case valves are not watertight, de-pressurize, empty and disassemble them.

Check the appearance and assembly status of seals; replace seals if necessary.

Conduct pressure and sealing test again.

Repeat the process as many times as required until there are no further leakages.

Basic cleaning:
If the disk type non-return valves come in contact with foodstuffs, the operator of the valves should clean the
fittings thoroughly before food is processed in it.
See the chapter "Cleaning, Disinfection" for this purpose.

Commissioning of disk type non-return valve

DANGER
The operator of the disk type non-return valves must ensure that those valves where the
media connections are not fully integrated into an enclosed pipeline or tank system and
therefore can be accessed from outside are provided with devices that reliably prevent
such access during commissioning and/or during operation of the valves.
The operator of the fittings must ensure that all people who have access to the disk type
non-return valves are made aware of the hazards.
CAUTION
Ensure that no foreign objects are present in the piping system.
Avoid temperature shock!
Warm up the fitting slowly to the operating temperature.
