Note
Use gaskets with the nominal size of the valve, to have a leak-proof sealing in both flow
directions.
The valve is adjustable. This means, the more the valve is closed the tighter it
becomes (
ā Fig.3-1).
Through the sophisticated triple eccentric design, the seat is relased from the disc
when opening the valve. This reduce wearing and extend the durability of the
valve.
To close the butterfly valves for liquids need less torque than valves for vapors
and gases.
The butterfly valve is tight in both flow directions. The preferred flow direction
is the direction towards the flat side of the disc. This direction is marked with
arrows on both sides of the valve.
