When the Butterfly valve lever operated Butterfly valve lever operated is fully open, the disc is rotated a quarter turn so that it allows unrestricted passage. Butterfly valve lever operated Butterfly valve lever operated may also be opened incrementally to regulate flow. There are different kinds of Butterfly Valves, each adapted for different pressures and different usage. When the butterfly valve is closed, the disc is turned so that it totally shut off the passageway. When the Butterfly valve lever operated Butterfly valve lever operated is fully open, the disc is rotated at a quarter turn so that it allows unrestricted passage. The Butterfly valve lever operated Butterfly valve lever operated may also be opened incrementally to regulate flow. There are different kinds of butterfly valves, that are adapted for different pressures and different usage. A Butterfly valve lever operated Butterfly valve lever operated is a rotational motion valve with a quarter turn. It is used to stop, regulate, and start flow.

Butterfly valve lever operated Butterfly valve lever operated of Features
Seat liner extending on to the contact faces ensures perfect sealing and eliminates the use of flanges gaskets.
Unique triple sealing system for sheft sealing and prevents extemal substances from entering the stem bore.
The thin profile, spherically machined hand polished disc provides a very high Cv and greater pressure recovery plus superior abrasion and erosion resistance in slurry or dry media applications.

Butterfly valve lever operated Butterfly valve lever operated is easy and quick to open. A right angle rotation of the handle provides a complete closure or opening of the butterfly valve. Large Butterfly valve lever operated Butterfly valve lever operated are usually comprised of a gearbox, where the hand wheel by gears is joined to the stem. This gives ease to the operation of the Butterfly Valve, but at the expense of speed. The construction of a Butterfly valve lever operated Butterfly valve lever operated body varies in design. A mostly used design is the wafer type that fits between two flanges. The lug wafer design is another common design that joins the two flanges and passes through the holes. Butterfly valve lever operated Butterfly valve lever operated is even available with threads that are flange and have butt welding ends, but they are not used often. These advantages are especially for large valve applications. The best and obvious advantages are saving of weight, space and cost. 

Butterfly valve lever operated Butterfly valve lever operated is built on the principle of a pipe damper. The flow control component is a disk of approximately the same diameter of the adjoining pipe, which rotates on either vertically or horizontally. When the disk lies collateral to the piping run, the butterfly valve is fully opened. When the disk approaches the 90 degree angle, the valve is shut.
