Design
Type EK ball valves have a unibody end-entry with an axial screw-type connection.
FK and HK ball valves have a two-piece split-body de-sign with flanged connection in between the two
halves.
Installation
The ball valves can be installed in pipelines by means of flanged connections or by welding.
Material requirements for welding must be ascertained from the manufacturer and must comply with
customer specifications.
The ball valves are designed for a normal load during service in pipelines. Under certain preconditions, the
ball valves can also be used for more severe operating conditions, although in such cases, the
manufacturer should be consulted in advance.
Impermissible Operating Procedures
To exclude any harmful effects on the seals, the substance to be used must comply with the ARGUS
technical specifications.
Consult ARGUS beforehand if necessary.
The combination of medium temperature and pressure are decisive factors for the choice of sealant
materials.
Danger!
It is essential that the limit values are not exceeded; these values can be taken from ARGUS
diagrams.
Warning!
The specified service pressures and temperatures must not be exceeded, even as individual
loads.
Caution!
The user is responsible for ensuring compliance with the guidelines, regulations, safety standards
and laws applicable to the use of these ball valves.
Maintenance
Ball valves are maintenance-free. It is advisable, however, to actuate them at least once or twice a year.
Safety Information
Information
Please read the safety instructions carefully!
General instructions
Installation and maintenance may be performed only by trained, qualified personnel.
The media to be used must comply with the ARGUS technical specifications in order to exclude any harmful
effects on the seals. Contact ARGUS for further information.
Danger!
It is essential that the limit values are not exceeded; these values can be taken from ARGUS
diagrams (see Section Designed Use).
Warning!
The specified service pressures and temperatures must not be exceeded, even as individual
loads (see Chapter Designed Use).
Caution!
The user is responsible for ensuring compliance with the guidelines, regulations, safety standards
and laws applicable to the use of these ball valves (see Chapter Designed Use).
Danger!
Local safety regulations must be com-plied with for transport to the place of installation.
Make sure that the valves cannot tilt or slip in any way (see Chapter Transport).
Warning!
After installation, the pipeline and ball valve must be rinsed through before the ball valve is
actuated (see Chapter Installing the Flanged Connection).
Danger!
The local welding regulations and specifications must be complied with when carrying out welding
work (see Chapter Installing the Welding Connection).
