Valvesonly is the best Pneumatic
Actuated Butterfly Valve Manufacturer in USA. A pneumatic actuated
butterfly valve is a type of control valve used in various industrial
applications to regulate the flow of fluid within a pipeline. This valve is
equipped with a pneumatic actuator, which utilizes compressed air or gas to
control the opening and closing of the butterfly valve. The design of the valve
includes a disc or plate, commonly referred to as the butterfly, which is
mounted on a spindle. When the actuator is activated, it causes the disc to
rotate, either allowing or restricting the flow of the fluid through the valve.
Key components of a pneumatic
actuated butterfly valve include:
ยท
Body: The valve body is
the outer casing that contains the internal components. It is designed to
withstand the pressure and temperature of the fluid flowing through the
pipeline. Common materials for valve bodies include cast iron, carbon steel,
stainless steel, and other alloys.
ยท
Disc/Butterfly: The
disc, often referred to as the butterfly, is a flat or slightly conical plate
that is mounted in the center of the valve body. When the valve is open, the
disc is positioned parallel to the flow direction, allowing for maximum fluid
passage. Conversely, when the valve is closed, the disc is rotated to a
perpendicular position, blocking the flow of fluid.
ยท
Seat: The seat is the
sealing surface where the disc comes into contact with the valve body when in
the closed position. It ensures a tight seal, preventing leakage when the valve
is closed. The seat is typically made of resilient materials such as rubber or
PTFE (polytetrafluoroethylene).
ยท
Actuator: The pneumatic
actuator is the component responsible for converting the input signal
(compressed air or gas) into mechanical motion to control the position of the
disc. There are different types of pneumatic actuators, such as diaphragm
actuators, piston actuators, and rack-and-pinion actuators. The choice of
actuator depends on factors like valve size, pressure, and application
requirements.
ยท
Positioner (Optional):
In some cases, a positioner may be added to enhance the precision and accuracy
of valve positioning. The positioner receives a control signal and adjusts the
actuator to achieve the desired valve position, ensuring precise control of
fluid flow.
