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
● 90-degree position: disc 
Working Principle of perpendicular to flow (stops 
a Wafer Type flow)
Butterfly Valve
● 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.
