Start-up
The start-up of the valve can be carried out provided the instructions indicated in Chapter 3
–
Receipt and Installation
have been followed.
4.1.
START-UP
Before start-up, the responsible persons should be aware of the operation of the valve and the
safety instructions to be followed. This instruction manual should be available to personnel at
all times.
This valve is suitable for use in food processes, cosmetics and pharmaceutical industry.
The following should be taken into consideration before starting up the valve/actuator:
•
Check that the pipe and valve are completely free from any traces of weld or other foreign matter. Carry out
the cleaning of the system if required.
•
Verify the smooth operation of the valve. If necessary, lubricate with special grease (see Chapter 6
) or soapy water.
•
Check for possible leaks and check that all the pipes and connections are watertight and leak free.
•
If the valve is supplied with an actuator, ensure that the actuator gives smooth operation.
•
Check that the air pressure at the inlet to the actuator is as specified in Chapter 8.
•
Ensure the quality of the compressed air in accordance with the specifications described in Chapter 8
Technical
Specifications.
•
Operate the valve.
4.2.
OPERATION
Do not touch the moving parts of the valve when the actuator is connected to the compressed
air.
Never place fingers inside the body when you have assembled a pneumatic actuator.
Danger of burns! Do not touch the valve or pipes when hot liquids are circulating or when
cleaning and/or sterilization are being carried out.
Do not modify the operating parameters for which the valve has been designed without
written prior authorization from INOXPA.
Visually check that the sealed area has no leaks. The valves are provided with a leak detector.
The valve must be oriented so that the leak detector is visible to the plant personnel. In the
case of a leak, replace the diaphragm with a new one and clean the seal area of the actuator
of any fluid residue that may have remained.
Place the valve so that, if leakage occurs through the detector, the fluid cannot come into
contact with personnel. This is particularly relevant in the case when hot liquids are
circulating or cleaning and/or sterilisation is being carried out.
