CAUTION
Cold/hot pipelines and/or ball valve.
Risk of injury due to thermal influences!

Insulate the ball valve.

Attach warning signs.
Medium escaping at high speed and high/low temperature.
Risk of injury!

Wear the prescribed protective equipment
Improper disassembly of the actuator.
Personal injury and property damage
Disassembling a pressurised actuator leads to uncontrolled pressure relief!

Before dismantling the actuator, close the pressure supply

Release the pressure from the cylinder.
NOTICE
Impermissible stress due to operating conditions and extensions / added structures.
Leakage or rupture of the valve body!

Provide suitable support.

Additional loads such as traffic, wind or earthquakes are not explicitly considered as standard
and require a separate design.
Condensation in air conditioning, cooling and refrigeration plants.
Icing!
Blocking of the actuation mechanism!
Damage due to corrosion!

Insulate the ball valve diffusion-tight
Incorrect installation.
Damage to the ball valve!

Remove caps before installation.

Clean the sealing surfaces.

Protect the housing from impacts.
Painting of ball valve and pipelines.
Functional impairment of the ball valve / loss of information!

Protect stem, plastic parts and type plate against the application of paint.
Impermissible stress.
Damage to the control mechanism!

Do not use the ball valve as a foothold.
Exceeding the maximum permissible operating conditions.
Damage to the ball valve!

The maximum permissible working pressure must not be exceeded, and the minimum and
maximum allowable working temperatures must be observed.

Lay the welding/brazing bead in several sections so that the heat build-up in the middle of the
enclosure does not exceed the maximum permissible operating temperature.
Particles and other contaminants in the conveyed medium.
Damage to the ball valve / internal leak!

Remove particles/contaminants from the conveyed medium.

It is recommended to install strainers / dirt filters in the pipework system.
Incorrect earthing during welding work in the pipeline.
Damage to the ball valve (burned spots)!

Remove bonnet during welding.

Do not use any parts of the valve for earthing during electric welding work.
