• 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 rerouting of the piping!

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

Foreign particles can damage the valve and the actuator; this can be avoided by

tting a suitable dirt trap.

• Wastheprotectivecoatremovedfromthe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 graphite sealing sets can cause

damage and leaks. Pay particular attention to the relevant chemical resistance

lists.

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

thedirectionofowofthemedium?

If not, the valve will not work.

• Arethepipingangesequiaxialandparallelanddoesthe

distancebetweenpipeendscorrespondtothevalvelength?

If not, excessive tension, valve malfunctions and leaks at the ange connections

may result.

• Is the piping routed correctly and is the valve free from

additionalpipingforces?

If not, leaks may develop and, depending on the situation, the valve may fail.

• Is the installation position of the valve with vertical valve
