The 4% 20-Inch Wafer Butterfly Valve A Comprehensive Overview In modern industrial applications, fluid control is critical for optimizing processes and ensuring safety. One essential component in this domain is the butterfly valve, specifically the 4% 20-inch wafer butterfly valve. This versatile valve type is pivotal in managing the flow of liquids, gases, and slurries across various industries, including water treatment, oil and gas, and HVAC systems. Design and Construction The 4% 20-inch wafer butterfly valve features a disc that rotates around a vertical axis to control fluid flow. Its wafer design means that it is installed between two flanges and does not require additional support brackets. This attribute makes installation simpler and reduces the valve's overall weight compared to other valve types. The primary components include 1. Disc The disc is a critical element that opens or closes to control the flow. Typically made from durable materials such as stainless steel, ductile iron, or plastic, the choice of material often depends on the medium being controlled and environmental conditions. 2. Body The body holds the internal components and is designed to withstand high pressures. Wafer valve bodies are generally flatter and more compact than flanged valves, offering greater flexibility in installation. 3. Seat The seat is the sealing surface against which the disc closes. Depending on the application, seats can be made from elastomers, plastic, or metal, providing a reliable leak-proof seal. 4. Operator The actuation mechanism can be manual (using a lever or handwheel) or automated (using an electric, pneumatic, or hydraulic actuator). The choice of actuator affects the valve's responsiveness and operational efficiency.
