Double Eccentric butterfly valve
Double Eccentric butterfly valve is high performance butterfly valve , which are made to completely close or open a passage of the functioning medium flowing via a pipeline. They can also be applied for flow-control objectives. Anyway, a hundred percent tightness of the valve cannot be promised in a long-term use for control objectives. The high performance butterfly valve can be mounted into vertical, horizontal or inclined pipeline so that the shot stamped on the valve body matches with the way of the power (arrow points from top pressure to lesser when the disc is closed), and the rotating disc axe is in a horizontal place. The type of bolt at the pivot area is also very vital. When there is a butterfly valve with electric actuator it is vital to abide the actuators producer.
