Feature / Application:The butterfly valve derives its name from the wing-like action of the disc which operates at right angles to the flow. It’s main advantage is a seating surface which is not critical. It is designed for fl ow isolation. The disc impinges against a resilient liner to provide bubble tightness with low operating torque. Compact and with a simple construction, butterfly valves facilitate easy pipe arrangement. Due to disc, they have slightly reduced flow characteristics

Butterfly Valve
Advantages: quick acting, good regulating characteristics, compact & light, low pressure isolation. Butterfly valves are simple, reliable and range in size from
40mm to 1000mm and beyond. They can be controlled by a notched lever, handwheel as well as by pneumatic or electric actuator. A shaft turns a disc 90º within a pipe.
