ValvesOnly are the topmost Butterfly Valve Manufacturers in USA. Butterfly valves are a type of quarter-turn rotational motion valve that is used in pipelines to turn off flow. Butterfly valves are frequently mentioned as a method for regulating flow. These valves are installed for an extensive range of applications mainly water supply, distribution and collection systems and plumbing systems. They have a variety of usage in flow isolation.
What are the main parts of a Butterfly Valve?
The main butterfly valve components include the valve body which is situated between the ends of the valve, which can either be flanged, lug or wafer. The disc is attached to the body of the valve as its basic function is to act like a gate that allows or restricts flow. The disc is usually drilled to fit in the stem or the shaft. There are several modifications in disc design, orientation, and material used to optimize flow, sealing, and/or operating torque. A strong rubber or metal anti-leak seal lines the internal valve body, securing the disc in the closed position for complete shutdown. The valve shaft, also known as the stem, attaches the disc to the actuator mechanism and transmits torque by using it. Seals are used at different points within the valve to either provide a tight seal throughout operation or to separate the process medium from the valve's internal components, which leads to a more versatile and cost-effective design.
How does a Butterfly Valve work?
The design of a butterfly valve is very basic, with the fluid flow controlled by its rotation of the valve disc. In the closed position, the disc closes the valve bore; in the open position, the disc is parallel to the flow direction, allowing flow. Butterfly valves often give bidirectional flow and cutoff capability. However, they are not full-bore, making them not suitable for pigging or swabbing. The body is made of ductile iron, and both the interior and external surfaces are coated with epoxy powder. Handwheels, gears, actuators, or a mix of the three are commonly used to operate the valves, depending on the individual applications requirements and technical specifications.

What are the features of butterfly valve?
- They have a simple structure, are lightweight, have small volume and consume low material.
- Since they are lightweight and their sizes vary, they can be easy to install.
- These valves are mainly used to cut off, attach and control the flow of the media which is in the pipeline. They have incredible fluid control features and tight sealing which prevents leakage.
- They provide good regulation.
- The butterfly plate's streamlined shape minimizes fluid resistance loss, making it an energy-efficient device.
- As Butterfly Valve Manufacturers in USA, we make sure that our valves are designed from premium materials and provide long service life.
