FEATURES
• Sturdy, compact construction, especially suitable for industrial applications.
• Installation in any position.
• Mechanical position indicator.
• Lockable rotation angle from 0 ° to 90 ° .
• Without zero setting.
• External tightness by means of two "O" rings.
• Easy conversion on field from manual to automatic servicing.
• Wide range of accessories on request:
• manual control lever
• 1 o 2 internai reductions with respect to the nominal diameter of the valve
• Butterfly dise AISI 304 for air temperature up to 200 ° C.
1. WARNING
Installation, adjustment and maintenance of the valve must be carried out
exclusively by skilled and authorized service technicians.
Non-proper installation, adjustment, changes, use and maintenance may cause
damages to the personnel or to the equipment. Consequently, it is necessary to
respect strictly the following instructions and local prescriptions for both the
installation of electric devices, in case of motorized valves, and of gas systems.
2. INSTALLATION
2.1 Make sure that all operating data indicated on the valve plates correspond to those
of the system.
2.2 When installing the valve be sure that there is sufficient clearance above the gear
caver and that it can be easily accessible in order to perform manual servicing,
automatic servicing by means of a gear motor or servicing by means of levers.
2.3 The installation of the BFV valves can be performed in any position but the position
with horizontal axis is recommendable.
2.4 The valve can be installed in any location except where acid fumes or other
deteriorating vapour may attack its metal parts or where gas leaks or explosive
vapours are present in the atmosphere.
2.5 Do not use the valve as a lever.
3. OPERATING
3.1 Before operating the following points must be checked carefully:
• tightness of the external gas pipes;
• that valve adjustment is performed within the requested angle range;
• that mechanical locks or other retainers, which may damage the valve, have
been removed.
3.2 Once these preliminary checks have been performed, the main gas tap can be
opened and the operation test can be curried out.
4. MAINTENANCE AND CHECKS
4.1 The BFV valves do not require any particular current maintenance because they do
not need lubrication.
4.2 lt is recommendable to check at least once a year that the mechanical connections
have not been modified, especially in case of systems, which do not function
vibration-free.
5. REPLACEMENT
ln case replacement of the BFV valve is necessary, proceed as follows:
5.1 Close the main gas tap.
5.2 Remove the mechanical connections from the valve axis.
5.3 Remove the valve body from the inlet and outlet flanges by loosening the fastening
screws from the respective nuts.
5.4 lnstall the new valve proceeding as per instructions reported in the foregoing
chapters.
Ali the reported data are subject to be changed without notice.
