1.3 Before installation, check the following items:

• Theoperatorisrequiredtocarefullycheckthesuitabilityofthe

controlvalveforitsintendeduseinthesysteminadvance.

Any use not in compliance with the regulations/specications can lead to serious

damage to the control valve or may lead to failure of the facility!

• Doesthenominal/operationdataontheratingplatematch

theoperationaldataofthefacility?

A mismatch may cause considerable damage to the valves.

• Atthepointofinstallation,isthereenoughspacetotand

removethevalve?

A lack of space can cause considerable problems and in the some cases

necessitate expensive rerouting of the piping!

• Wasthepipingushedandcleanedpriortotheinstallation?

Foreign particles can damage the control valve and accessories; this can be

avoided by tting a suitable dirt trap.

• Wastheprotectivecoatremovedfromthecontrolvalve,and

wasthevalvecleaned?

The preservative (Mipa Abziehhaut blue) and the spray (Castrol Safecoat

DW 32) can contaminate the operating medium and must be removed before

installation.

Unsuitable cleaning agents that attack the PTFE and graphite sealing sets

can cause damage and leaks. Pay particular attention to the relevant chemical

resistance lists.

Remove covers.

• Doesthedirectionofowarrowonthehousingcoincidewith

thedirectionofowofthemedium?

If not, critical operating conditions can result that may damage the control valve,

as they are not designed to cope with this situation.
