Butterfly Valve KISTLER BFV Series Is a valve used to turn on / off from 0 to 90 degrees. Butterfly valves are popular in industrial systems. Whether it is the production of various industries, in cold water casting systems of large air conditioners, in plumbing work, in the water system, waste water, etc.
Butterfly Valve KISTLER BFV Series The butterfly valve is a valve in the valve family called the Quarter-turn Valve (or a valve that can be broken one quarter of the circle). Is the valve tongue that is a circular metal plate connected to the valve stem. When the valve is closed The valve tongue is completely rotated to the position of the fluid flow.
