What is a Wafer Type Butterfly Valve? ● A quarter-turn rotary valve ● Disc pivots within the body to regulate fluid flow ● Lacks protruding lugs for bolting directly to pipelines ● Sandwiched between flanged pipe connections
Components of a Wafer Type Butterfly Valve > Body: houses internal components and provides connection points (cast iron, ductile iron, stainless steel) > Disc: heart of the valve, controls flow (stainless steel, coated steel, plastic) > Stem: connects disc to actuator and transmits turning force (manual lever, gear operator, or pneumatic/electric actuator)
● 90-degree rotation for full flow control
Working Principle of a Wafer Type Butterfly Valve
● 90-degree position: disc perpendicular to flow (stops flow)
● 0-degree position: disc parallel to flow (allows unrestricted flow)
Advantages of Wafer Type Butterfly Valves Their compact design makes them ideal for applications with limited space constraints. They are lightweight compared to other valves, simplifying installation and reducing stress on the pipeline. The simpler design and fewer parts contribute to a lower overall cost compared to some other valve types.
Conclusion Wafer type butterfly valves are a versatile and cost-effective choice for a wide range of industrial applications. Their compact design, ease of installation, and bi-directional flow capability make them well-suited for various piping systems. However, it's important to consider their limitations, such as pressure rating and throttling capability, when selecting the right valve for your specific needs.
