Inside the body, the flow area of the fluid is regulated by a moving shutter. When the obturator rests on the seat the valve is completely closed, when instead it is at its maximum distance, the valve is completely open.
They are operated by means of a handwheel placed on the rod.
The closure must be carried out exclusively by hand, without the use of levers, which would compromise the shape of the sealing devices. ATTENTION:
In case of high temperatures, use hand protection gloves to act on the switching device.

For a correct assembly, install the valve following the flow direction indicated by the arrow stamped on the body.
The valve can be mounted both horizontally and vertically.
For the sealing on threads use a material compatible with the fluid used.
Screw the valve onto the threaded pipes, positioning the key exclusively on the special hexagonal parts up to reach the valve lock on the pipe (this item has a thread-bottom stop where the pipe rests).
After connecting the valve to the pipes, check that the valve is not subjected to stress due to the pipes, then use heavy clamps to support the pipes.
Slowly open the upstream shut-off devices to avoid water hammer.
No maintenance operations are foreseen, except for the adjustment of the screw cap in case of licking from the rod.
