Areas of application and function
sera
diaphragm pressure keeping valves can be used for liquid
media without solid matters but exclusively for the intended
use as specified by the manufacturer.
sera
diaphragm pressure keeping vavles are used to generate
a defined backpressure on the pressure side of oscillating dis-
placement pumps and thus to avoid excess supply.
CAUTION !
diaphragm pressure keeping valves are no tightly
closing shut-off valves.
CAUTION !
Do not change the setting of the pressure keeping valve!

Test / identification
sera
diaphragm pressure keeping valves are tested in our
works and set to an operative pressure.

Checking the packaging at the place of

Report any external damage immediately to the transport
company, and fill in a damage report. After the transport com-
pany has recorded the damage, open the package and check
the contents for damage.

Storage
An undamaged packaging protects the unit during subsequent
storage and should only be opened when the diaphragm pres-
sure keeping valve is installed.
Proper storage increases the service life of the diaphragm
pressure keeping valve and comprises prevention of negative
influences such as heat, humidity, dust, chemicals etc.
The following storage instructions are to be observed:
•
Storage place: cool, dry, dust-free and slightly ventilated
•
Storage temperatures between -10°C and +45°C
•
Relative air humidity not more than 50%.
If these values are exceeded, metal products should be sealed
in foil and protected from condensation water with a suitable
desiccant.
Do not store solvents, fuels, lubricants, chemicals, acids, disin-
fectants and similar in the storage room.
