CONFORMITY
REQUIREMENTS
THE IMPORT-EXPORT OF
CONFLOW
PRODUCTS FROM ONE COUNTRY TO ANOTHER IS
REGULATED BY SAFETY AND TRADE LEGISLATION IN THESE COUNTRIES. BEFORE
SENDING THE PRODUCT TO A THIRD COUNTRY, CHECK THE PRODUCT DOES NOT
CONFLICT WITH THE REGULATIONS OF THAT COUNTRY.
Before installing the valve, remove the plastic guards covering the flanges and the connection couplings.
ATTENTION
During commissioning of the valve or during operation, do not touch the body which could
conduct heat if the fluid used is at high temperature.
ATTENTION
During operation, do not touch the stem as it is in movement, it may be hot and could catch
your finger or clothing.
ATTENTION
During operation, do not touch the motor, the surface temperature of the motor could rise
and therefore could cause abrasion.
ATTENTION
Before starting any maintenance operations, ensure the valve is not pressurised and/or hot.
ATTENTION
Do not remove the descriptive label fastened to the yoke since it reports the serial number,
data which is indispensable for tracking the valve over time.
Please refer to this number for supply of spare parts
Do not remove the stroke label which is the main reference for valve calibration
ATTENTION
The electrical actuator must be handled solely and exclusively by competent and authorised
staff
ATTENTION
Before removing the cover of the actuator, ensure the main power supply is disabled,
preventing any possible involuntary removal. The live areas must be isolated before starting to work.
ATTENTION
Ensure the actuator always works in optimal conditions, any damage or error and change
of operating characteristics, which may regard safety, must be notified.
Non-compliance with the main safety information, the standards in force and the assembly instructions can:
•
Cause danger for the safety of those carrying out manoeuvres or for third parties.
•
Damage the valve or adjacent objects.
•
Compromise the efficient operation of the valve.
2 - GENERAL ASSEMBLY INSTRUCTIONS
2.1 – ASSEMBLY ON THE SYSTEM (GENERAL NOTES)
Before assembling the valve, accurately clean the tubing with compressed air, water or another blowing fluid to eliminate
foreign bodies, welding waste and various dirt that could damage the sealing surfaces of the valve.
ATTENTION
Assemble the valve with the direction arrow imprinted on the body in the same direction
as the tubing fluid.
Assembly is however recommended of a “Y” filter (our “FY” series) on the tubing, upstream of the valve.
Assembly of the valve can be carried out in the vertical or horizontal position, see Figure 1, page 4. You are however
advised to assemble vertically to prevent wear of the trim due to the weight and relevant rubbing.
ATTENTION
It is forbidden to weigh the valve down with foreign objects. It is compulsory to protect the
valve from external stress.
