If appropriate, in the event of a fault in the valve (in a plant which is in operation) inform the
shift foreman / safety engineer or the works manager without delay about the fault, in order, for
example, to avoid an outflow / overflow of chemicals or the discharge of gases in good time by
means of suitable measures!
Before mounting or repair, relief the pressure from pneumatic / hydraulic devices / machines /
plant.
Empty the conduit from medium.
If necessary, set up warning signs in order to prevent the inadvertent starting up of the devices /
machines / plant.
Observe the respective relevant professional safety and accident prevention regulations when
carrying out the mounting / repair work.
Check the correct functioning of the safety equipment (for example the emergency push off but-
tons/ safety valves, etc)!
3.1.2 Safety advice for adjustment and starting
As a result of the starting (pneumatic or by hand) of a pressure actuated valve the flow of gases,
steam, liquids, etc. may be enabled or interrupted!
Satisfy yourself that, as the result of the starting or the test adjustments of the valve, no potential
hazards will be produced for the personnel or the environment!
If necessary, set up warning signs in order to prevent the inadvertent starting up or shutting down
of the devices / machines / plant.
By ending mounting check the correct function and the tightness of the valve.
Check the right position and correct function of mounted pilot valves and limit switches
Through suitable measures, prevent actuating links being trapped by moving actuating elements!
Check the right function of all safety devices (for example emergency off push buttons / safety
valves, etc. )!
Carry out the starting and the adjustments only in accordance with the instructions discribed in
this documentation!
When adjustments are being carried out on an opened and switch on (operational) limit switches
or pilot valves, there is the risk that live parts(230V AC~) can be touched!
Therefore the adjustment must be carried out only by the electrician or a person having adequate
training, who is aware of the potential hazard.
