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

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

ofnoiseandvibration.

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

• Incorrectmaintenancecanresultin the operating medium

escaping.

Danger of burns, freezing!

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

surfaceofthevalve.

Danger of burns, freezing!

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.
