Installation
Before installation, ensure that the angle seat valve is suitable for the operating conditions.
These include function, materials, operating pressure und working media in connection with operating
temperature. Depending on the operating conditions and weight of the valve a suitable fixture has to be
applied.
Take also care for aligning pipes.
Clean pipes before installation.
Follow the laws, directives and regulations for welding which are valid in your country.
Disassemble the valve before welding. See chapter 5.3.2.
Weld in valve body and cool down.
Assemble actuator on valve body, see chapter 5.3.1.
5.4.1. Installation - Butt weld spigots:
Remove the actuator before welding the valve body into the pipeline. Allow the welding nozzles to cool after
welding. Reassemble the valve body and drive.
5.4.2. Installation - Clamp connections:
When assembling clamp connections, insert a gasket between the body clamp and the adjacent piping clamp
and join them using the appropriate clamp fitting. The gasket and the clamp for clamp connections are not
included in the scope of delivery.
5.4.3. Installation - Threaded connections:
Screw the threaded connections into the piping in accordance with valid standards. Screw the valve body into
the piping, use appropriate thread sealant. The thread sealant is not included in the scope of delivery.
