Butterfly Valve

Butterfly Valve: 

                                      

                        Butterfly valves are quick opening valves that consist of a metal circular disc or vane with its pivot axes at right angles to the direction of flow in the pipe,which when rotate on a shaft, seals against seats in the valve body.The are normally used as throttling valves to control flow.Butterfly valves control the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle,which permits flow in only one direction.These valves offer a rotary stem movement of 90 degrees or less,in a compact design.Unlike ball valves,butterfly valves do not have any pockets in which fluids may become trapped when the valve is closed.
