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.

Damage to the ball valve!
Remove caps before installation.

Clean the sealing surfaces.

Protect the housing from impacts.


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.

