Gear Operated Flanged Butterfly Valve 1000mm
A butterfly valve is a valve which can be used
for through or cut off flow. The closing mechanism takes the
form of a disk. Operation is similar to that of a ball
valve, which allows for quick shut off. Butterfly valves are
generally favored because they are lower in cost to other valve
designs as well as being lighter in weight, meaning less support is
required. The disc is positioned in the center of the pipe, passing
through the disc is a rod connected to an actuator on the outside
of the valve. Rotating the actuator turns the disc either
parallel or perpendicular to the flow. Unlike a ball valve, the
disc is always present within the flow, therefore
a pressure drop is always induced in the flow, regardless
of valve position.
There are different kinds of butterfly valves, each adapted for
different pressures and different usage.
This type of butterfly valve operated by the electric motor, and
also can by manual, It has a motor and wormgear box on
the head of valve. The wormgear are planetary gear operated. This type of gearing allows the use
of a relatively small handwheel and operating force to operate a
fairly large valve.
