2. Commissioning Themediumandthevalvecanposethefollowinghazards:

• Criticaloperatingconditionscancauseimpermissiblelevels

EN

ofnoiseandvibration.

Hearing loss, vascular and nerve problems, damage to joints and bones!

• Incorrectmaintenancecanresultintheemissionofthermal,

cryogenicandtoxicoperatingmedia.

Danger of burns, freezing, acid burns, poisoning!

• Thetemperatureoftheoperatingmediumistransferredtothe

surfaceofthevalve.

Danger of burns, freezing, explosion!

Asthesehazardscanallbecontrolledbytheplantoperator,

theoperatorisobligedtocomplywithnationalandinternational

environmentalregulations,installsuitableprotectivemeasures

toensureworkplacerequirementsaresatised,andtoinstruct

hisemployeesaccordingly.

Due to the risk of injury, it is prohibited to work between

the yoke/columns while the valve is in operation.

 Oncethesehazardshavebeenavertedbyadoptingappropriate

protectivemeasures,thevalvecanbeinstalledandconnected

inthepiping.Thefollowingpointsshouldbenoted:

• Flangeconnection:

 Connectionmaterial(gaskets,bolts,nuts)arenotpartofthe

scopeofsupply.

Locate gaskets in the centre of anges, failure to do so can result in leaks and

increased noise levels.

If a completely installed piping is to be ushed or blown through for cleaning,

replace the control valve with a matching piece.

• Weldedconnection:

 Welded connections have to be made in compliance with

applicableweldingregulations.

After welding, carefully clean the piping again. Open control valves properly and

remove any accumulated foreign particles. Advise the manufacturer in writing

that the tting has been opened!
