Danger:
Safe operation of the valve is only ensured if the valve is installed, commissioned and
serviced by qualified personnel in compliance with warning references in this SDI. In
addition, the general installation- and safety regulations for pipelines respectively plant
construction and the professional use of tools and safety equipment must be guaranteed.
Observe unconditionally during all work on the control valve. Ignoring this information may
cause physical or material damage.
Storage:
• Storage temperature -20°C to 65°C, dry and free of dirt.
• Do not damage the lacquer. The lacquer is a foundation intended only as a protection against corrosion
while in storage and during transport.
• In rooms where moisture or condensation are present use heating or a drying agent to maintain a
moisture free atmosphere.
Transport:
• Transport temperature -20°C to 65°C.
• Protect against external forces (shock, Vibration etc.).
• Do not damage the protective lacquer.
Handling prior to installation:
•
For valves with protection caps, remove these directly before installation.
•
Protect valve of adverse weather conditions e.g. rain, splash water, or use dehumidification agent.
•
Careful treatment prevents damages.
General installation information:
In addition to general installation instructions, please observe the following points:
•
If used, remove flange covers.
•
Ensure that valve body and piping are free of impurities.
•
Pay attention to position of the valve relative to the flow direction. Note arrows on valve body.
•
Centre gaskets between flanges.
•
Mating pipe flanges must be of identical type.
•
Ensure installation without tension and torque.
•
Do not use the valve as a step or fixation point. Only piping supports it.
•
Protect valve from dust or dirt on construction sites. Provide strainer or filter upstream of valve.
•
Use compensators to balance thermal expansion of piping.
•
Ensure that stem thread and shaft are kept free of paint.
