Operating instructions
8.7 Hydraulic accessories
The following chapter is intended to give you an overview of installation
options.
Please note that these operating instructions are no substitute for the
instructions supplied with the accessories in each case. The correspond-
ing documentation supplied with the product applies to safety informa-
tion and provides exact instructions on assembly.
8.7.1 Injection nozzle
If the pressure line enters a main line, it is advisable to install an injection
nozzle.
Injection nozzles have three main functions:
Dosing the medium into a main line,
Preventing fl owback into the pressure line through a non-return valve.
Notes on assembly:
Double-ball injection nozzles must be installed into the main line
vertically from the bottom. You can install hose and spring-loaded
injection nozzles any way you like.
With dosing media that tend to crystallize, it is advisable to carry out
installation into the main line from the bottom. This prevents air
bubbles from being trapped.
Many dosing media tend to contaminate the injection nozzles, which
can lead to blockages. In cases like this, it is advisable to install an
injection nozzle that is easy to dismantle and block off.
