5-6 EB 8097 EN
Installation
7. Mount the valve-actuator extension back
onto the valve body and fasten the clamp
connection.
8. Attach a support or suspension on the
valve, if necessary.
9. Versionwithsteambarrier: connect the
compression-type ttings to the steam
supply line.
b) Valvewithanges,threaded
endsorclampconnections:
To meet 3-A conformity requirements, a gas-
ket recommended by 3-ASanitary Stan-
dards Inc. (see website
uhttp://www.3-a.org) must be used for a
Type3347 Valve with threaded ends accord-
ing to DIN11851/DIN11887.
1. Proceed as described for “Version with
welding ends” (steps 1 to 4).
2. Make sure that the correct ange gaskets
are used.
3. Bolt the valve to the pipe free of stress or
fasten the clamp connections to the pipe.
4. Proceed as described for “Version with
welding ends” (steps 8 to 9).
5.4 Testing the installed valve
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Valves and pipelines are pressure equipment
that may burst when handled incorrectly.
Flying projectile fragments or the release of
process medium under pressure can cause
serious injury or even death.
Before working on the control valve:
Î Depressurize all plant sections affected
and the valve (including the actuator).
Release any stored energy.
Î Drain the process medium from the plant
sections affected as well as from the
valve.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or ashing)
may occur during operation caused by the
process medium and the operating condi-
tions. Additionally, a loud noise may briey
occur through the sudden venting of the
pneumatic actuator or pneumatic valve ac-
cessories not tted with noise-reducing t-
tings. Both can damage hearing.
Î Wear hearing protection when working
near the valve.
