Mounting of the double regulating
valve
WARNING
Risk of injury from pressurised components!
Media escaping under pressure can cause injuries.
!
Only carry out installation work when the
system is depressurised.
!
For retrofi tting an existing system: Drain the
system or shut off the supply pipes of the
system section and depressurise the system
section.
!
Wear safety goggles.
CAUTION
Risk of injury on hot or cold components and
surfaces!
!
Wear suitable protective clothing to avoid
unprotected contact with hot or cold fi ttings
and system components.
!
If necessary, wait until the component
has reached approximately the ambient
temperature before working on it.
NOTICE
Damage to property due to lubricants!
Seals can be destroyed by the use of greases or oils.
!
Do not use greases or oils during mounting.
!
If necessary, fl ush dirt particles and grease and
oil residues out of the pipework.
!
When selecting the operating medium, observe
the current state of the art.
!
If the operating medium is contaminated, install
a strainer in the supply pipe.
•
The valve can be installed in any position.
•
For maintenance purposes, we recommend
installing shutoff valves upstream and
downstream of the valve or system section.
Make sure that the product and the pipework are free
from contamination.
Mount the valve so that the fl ow is in the direction of
the arrow. (Note the marking on the body.)
Make sure that there is a straight pipe section with
40
Protected from UV rays and
direct sunlight
Do not store together with
solvents, chemicals, acids, fuels or
similar substances
L = 3 x Ø upstream of the valve and a straight pipe
section with L = 2 x Ø downstream of the valve.
Install the product free of tension.
Make sure that the valve remains easily accessible.
