2. 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

3. 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)

4. Working Principle of a
Wafer Type Butterfly
Valve
●90-degree rotation for full flow
control

●90-degree position: disc
perpendicular to flow (stops
flow)

●0-degree position: disc parallel
to flow (allows unrestricted
flow)

5. 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.

6. 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.
