NOTICE

Pay particular attention to correct hy-
giene and ensure that regulators for 
the food and pharmaceutical indus-

tries are kept absolutely clean.
Used tools must be free of sol

-

vents and grease.

 

Only use a lubri

-

cant suitable for foodstuffs (order no. 
8150-9002) for parts that must be 
lubricated.

Choose a place of installation that allows 

you to freely access the regulator even after 
the entire plant has been completed and al-

lows unobstructed set point adjustment.

Before installing the regulator in the pipeline, 
clean the pipeline thoroughly to remove any 

foreign particles in the plant which could af

-

fect the regulator's proper functioning.
The plant must be designed and the pipe-

lines installed in such a way that the regula

-

tor can be mounted and operated without 

any tension. If necessary, support the pipe-
line near to the connections. Do not attach 
supports to the regulator itself.

Select a straight section of pipeline without 

any disturbances as the site of installation for 

the regulator (to ensure that the control func

-

tion is not affected by the flow conditions).

4.1  Mounting position

The regulator has an angle-style 
valve body. The actuator hous-

ing must face upwards. As a re

-

sult, the outlet must face to the 
side in the installed position.

 

−

Direction of flow must match the direc

-

tion indicated by the arrow on the body 
(inlet at the bottom and outlet at the 
side).

4.2  Shut-off valve and pressure 

gauge

Install a manually operated shut-off valve up-

stream and downstream of the regulator. This 
allows the plant to be depressurized, if re

-

quired. In addition, it serves to relieve the 

operating diaphragm of pressure when the 

plant is not operated for extended periods.

A pressure gauge downstream of the regula

-

tor allows the set point (to control the output 

pressure p

2

) to be monitored.
