Introduction
Resilient seated butterfly valves are an essential component of a wide range of industrial and commercial piping systems. These valves are designed to provide high levels of pressure, temperature, and flow control for various media in a variety of applications. A comprehensive understanding of their design features, choice of materials, and installation instructions is essential for ensuring effective operation. This blog post provides a detailed overview of what you need to know about resilient seated butterfly valves.
Overview of butterfly valves
Butterfly valves are quarter-turn valves that comprise of a disc that rotates in the middle of a pipe. The rotating action of these valves is used to open and close a passageway where flow is regulated. Depending on their design, butterfly valves can be used with liquid, air, or vacuum applications. Their main benefits include ease of installation, lightweight construction, and high pressure capability. Additionally, due to their higher Cv ratings and lower pressure drops compared to other mechanical control valves, butterfly valves are often preferred over other options for regulating the flow of liquids in pipelines.
Definition of resilient seated butterfly valves
Resilient seated butterfly valves are a type of butterfly valve that features a seating surface made from elastomeric material such as rubber, allowing them to be used in more demanding applications. This design allows for no metal-to-metal contact, reducing wear on the sealing surfaces and resulting in better long-term performance. The elastomeric seat also provides improved resistance to corrosion and can handle higher temperatures without deformation. Additionally, due to the lack of gaskets or flanges, these valves require less maintenance than other types of valves.
Features and Benefits
Butterfly valves feature a variety of features and benefits that make them popular for many kinds of applications. One of their main advantages is the ease of installation and lightweight construction, making them a cost-effective solution when compared to other valve types. Additionally, their quarter-turn operation means they can be quickly and easily opened and closed, making them ideal for system automation. Butterfly valves also have a high pressure rating, as well as higher Cv ratings and lower pressure drops than other mechanical control valves, which makes them suitable for regulating flow in pipelines with low pressure losses.
Furthermore, resilient seated butterfly valves are an excellent choice for more demanding applications due to their elastomeric seat which eliminates metal-to-metal contact and provides improved resistance to corrosion while being able to handle higher temperatures without deformation. Finally, these types of valves also require less maintenance than other types due to the lack of gaskets or flanges.
Design considerations for resilient seated butterfly valves
Resilient seated butterfly valves have a number of design considerations that must be taken into account when selecting them for an application. The most important factor is the type and quality of the elastomeric material used for the seat, as it will determine the valve’s ability to protect against corrosion and high temperatures. Additionally, it is important to consider the pressure rating of the valve, as well as whether or not it has a lugged or wafer butterfly valve.
It is also essential to keep in mind the diameter of the pipe that will be connected to the valve, as well as any other components used in conjunction with it. Additionally, valves should be inspected regularly for signs of wear and tear on their seating surfaces. Finally, when installing resilient seated butterfly valves, special care must be taken to ensure that they are properly aligned with both pipes and other components in order to maximize their effectiveness.
Advantages of resilient seated butterfly valves
Resilient seated butterfly valves offer several advantages over other valve types. Their elastomeric seat eliminates the need for gaskets or flanges, making installation simpler and less expensive while providing a much higher pressure rating than conventional metal seats.
Additionally, resilient seated butterfly valves also offer improved corrosion resistance compared to other types of valves, as well as better temperature protection. They also have a low pressure drop and high Cv values, making them ideal for controlling flow in pipelines with low pressure losses. Furthermore, they require less maintenance than other valve types due to their lack of hardware components that may need to be replaced regularly. Finally, the quarter-turn operation of these valves makes them easy to open and close during system automation.
Choice of Materials for Resilient Seated Butterfly Valves
When selecting materials for resilient seated butterfly valves, there are several factors that should be taken into account. First and foremost, the material used for the seat must be able to withstand high temperatures, corrosion, and pressure. Additionally, any sealant or gasket used should also be well suited for the application in order to ensure a reliable connection. Common materials used for resilient butterfly valve seats include EPDM rubber (ethylene propylene diene monomer), nitrile rubber (Buna-N) and PTFE (polytetrafluoroethylene).
Depending on the application, other elastomeric materials may also be considered as they offer improved resistance to oil and other chemicals as well as higher temperature tolerance.
It is important to note that all sealing materials will degrade over time due to wear or exposure to various chemicals; care must therefore be taken when selecting these components in order to maximize their longevity. Additionally, the valve body itself should also be made of a durable material that can withstand pressure and wear without corroding or failing; stainless steel is often recommended due to its strength and corrosion resistance.
