Installation
5.3.3 Signal pressure connec-
tion
Î
Connect the signal pressure to the signal
pressure connection on the pneumatic
actuator as described in the actuator
documentation.
5.4 Testing the installed valve
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Valves and pipelines are pressure equipment
that may burst when handled incorrectly.
Flying projectile fragments or the release of
process medium under pressure can cause
serious injury or even death.
Before working on the control valve:
Î
Depressurize all plant sections affected
and the valve (including the actuator).
Release any stored energy.
Î
Drain the process medium from all the
plant sections concerned as well as the
valve.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or flashing)
may occur during operation caused by the
process medium and the operating condi-
tions. Additionally, a loud noise may briefly
occur through the sudden venting of the
pneumatic actuator or pneumatic valve ac-
cessories not fitted with noise-reducing fit -
tings. Both can damage hearing.
Î
Wear hearing protection when working
near the valve.
Risk of personal injury due to exhaust air
being vented from pneumatically operated
components.
While the valve is operating, the actuator,
for example, may vent during closed-loop
operation or when the valve opens or closes.
Î
Wear eye protection when working in
close proximity to the control valve.
Risk of personal injury due to preloaded
springs.
Actuators with preloaded springs are under
tension.
Î
Before starting any work on the actuator,
relieve the compression from the pre-
loaded springs (see associated actuator
documentation).
