7.4.3 Weld or glue the valve body into the
pipeline
Before welding or gluing the body, the actuator and the
diaphragm must be removed.
The installation is divided into the following steps:
1. Disassemble actuator and diaphragm, see chapter „7.5".
2. → Weld or glue the valve body into the pipeline.
→ After welding or gluing in the body, smooth the valve body
surface by grinding if required.
→ Carefully clean the body.
3. Mount the actuator and diaphragm, see chapter „7.6".
7.4.4 Welding tank bottom body Type 2033
Recommendation
Observe sequence:
1. Weld the tank bottom body onto the base of the tank
before installing the tank. Welding onto a tank which has
already been installed is possible but more difficult.
Weld the tank bottom body in the middle of the tank base so
that the tank can be optimally drained.
2. Weld tank bottom body into the pipeline.
Installation requirements:
Pipelines: Ensure that the pipelines are aligned.
Preparation: Support and align pipelines. To ensure that the pipeline
is self-draining, we recommend the inclination angle
according to the valid ASME BPE.

DANGER
Risk of injury from high pressure.
▶ Before working on the system, switch off the pressure and vent
or drain lines.
For information on tanks and instructions on welding observe
the standard ASME VIII Division I.
Before you start welding, check the batch number indicated
on the supplied manufacturer's certificate 3.1.
Observe the applicable laws and regulations of the
respective country with regard to the qualification of
welders and the execution of welding work.
1. Welding tank bottom body onto the tank.
NOTE
Before welding, note the following:
▶ Use only welding material which is suitable for the tank bottom
body.
▶ The tank bottom valve must not collide with any other installation
part; the actuator must be easy to install and remove.
2. Welding tank bottom body into the pipeline.
→
Weld in tank bottom body.
Ensure installation is de-energized and low-vibration.
After welding in the valve body:
Install the diaphragm and the actuator, see chapter „7.6".
