This guide clarifies the naming conventions and key variants of industrial butterfly valves to aid in proper selection. It explains that terms like Wafer, Lug, Flanged, and Resilient Seated directly indicate critical design features such as connection type, sealing mechanism, and service capability. The article details the specific applications of each type: compact Wafer valves for general use, Lug valves for dead-end service, Flanged valves for high-pressure systems, and Resilient Seated valves for bubble-tight shutoff. It provides a framework for specification by outlining four essential selection factors: connection type, offset design, seat material, and dead-end service needs. Finally, it positions Tianjin Worlds Valve as a provider of ISO 9001-certified, customizable solutions across this full spectrum of butterfly valves for water, HVAC, chemical, and industrial applications.

Selecting the right butterfly valve for your system is a crucial decision that can affect the performance and longevity of your piping network.

The sealing principle and structural characteristics of flanged butterfly valves are the same as those of ordinary centerline butterfly valves.

The opening and closing part of the flanged butterfly valve is a flange. The movement direction of the flange is perpendicular to the direction of the fluid. The flanged butterfly valve can only be fully opened and fully closed and cannot be adjusted or throttled.
