The work described in this chapter may only be performed by
specialist personnel quali
fi ed to perform the corresponding task.
Danger of burning due to hot or cold components and pipe!
Valve components and pipes can become very hot or very cold
during operation and cause burns upon contact.
Ö
Let the components and pipes cool down or warm up.
Ö
Wear protective garments and protective gloves.
Danger of injury due to pressurised components and escaping
medium!
Ö
Do not loosen the test connection while the valve is
pressurised.
Danger of crushing due to moving actuator stem and stem!
Ö
Do not reach into the yoke as long as the pneumatic power is
connected to the actuator.
Ö
Before working on the valve, interrupt and lock pneumatic
energy and the control signal.
Ö
Do not allow the jamming of objects in the yoke to hinder the
operation of the stem and actuator stem.
Ö
If the actuator stem and stem are blocked (e.g. due to
“seizure” if not actuated for a long period of time”), release
the residual energy of the actuator (spring tension) before
releasing the blockage, see the corresponding actuator
documentation.
Danger of injury due to escaping exhaust air!
During operation, when regulating or when opening and closing
the valve, exhaust air can escape, for example from the actuator.
Ö
Wear eye protection when working near the valve.
Danger of injury due to residual medium in the valve!
When working on the valve, residual medium can escape and,
depending on the medium properties, cause injuries (e.g.
scalding, chemical burns).
Ö
Wear protective garments, protective gloves and eye
protection.
Ö
Do not loosen the test connection while the valve is
pressurised.
To decommission the valve for maintenance and repair work or
for disassembly, perform the following steps:
Ö
Close the valves upstream and downstream of the valve so
that no medium
fl ows through the valve.
Ö
Empty the pipe and valve completely.
Ö
Shut off the pneumatic power and lock it, to depressurise the
actuator.
Ö
Let the pipe and valve components cool down or warm up.
