Butterfly valves are found throughout the fluid based applications in the process control field. They are one of many common and special types of industrial valves used to regulate fluid flow in ways that are compatible with the media being controlled and the degree of precision needed to produce the desired process outcome.
The industrial process control field benefits from a large array of valve manufacturers in pursuit of the favor and business of process operators. Operators continually seek better performance and lower life cycle costs. Manufacturers respond with increasingly improved designs.
A butterfly valve has a disc that is positioned in the fluid flow path. It rotates around a central axis, the stem, through a 90 degree arc from a position parallel to the flow direction (open) to perpendicular (closed). A critical element of a butterfly valve is the seat, where the disc seals to the body in the closed position. Seat design should provide these positive operating attributes:
Flowseal, part of the Crane, CPE group of brands, utilizes their specially designed Soft Seat valve sealing arrangement on their resilient sealed butterfly valves. The Soft Seat feature provides beneficial fulfillment of process requirements for the attributes listed above. The valve is available in a range of sizes, with options and variants to meet a wide array of industrial process requirements.
Learn more about the Flowseal Soft Seat butterfly valves by watching the short video below. You can delve deeper with a browsing of the illustrative brochure that is also included below. It provides some detailed illustrations of how the seat functions under differing operating conditions. Contact a product specialist and share your process challenges. Your process knowledge and their product application expertise, when combined, will produce a useful solution.
