About
Double flanged butterfly valve are a particular variety of butterfly valve that has flanged ends on reciprocals of the valve body. They are often employed in large diameter piping systems where a safe a leak tight attachment is necessary.
Function
● To control the flow of fluids.
● To control throttle and regulate the flow of fluid.
● Can perform well in high temperatures.
Advantages
● Design provides double sealing minimizing fluid leaks and making them best possible for an intense environment.
● Their lightweight and compressed structure permits for easy installation and minimizes the system’s overall weight, making them favored in applications where space is limited.
● They are respectively reasonably priced and require less maintenance than other valve types.
● It has low maintenance cost.
Industries Using
● Oil and gas
● Chemical
● Power generation
Components
● Body: The body is the external part of a double flanged butterfly valve that holds the internal part of the valve.
● Handwheel: The handwheel imparts the force needed to rotate the disc to open and shut the valve.
● Stem: It is used to connect the handwheel and the valve disc.
● Gear box: It transmit rotation from handwheel to the valve stem
● Disc: It is assigned to open and close the valve.
● Seat: This is a component that forms a facet for the disc to let up when the valve is closed.
● Gasket: Prevent the fluid drip between the valve and pipe mating surface.
