What Is a Wafer Type Butterfly Valve Supplier?
A wafer type butterfly valve supplier is a manufacturer or distributor specializing in the production and supply of wafer-style butterfly valves for industrial flow control applications. These valves are designed to fit between two pipeline flanges and are secured using flange bolts that pass through the entire assembly.
Wafer butterfly valves are among the most popular valve types because they are:
- Lightweight
- Compact
- Economical
- Easy to install
- Suitable for a wide range of industries
They are widely used in water treatment, HVAC, chemical processing, food production, and industrial utility systems.
What Is a Wafer Type Butterfly Valve?
A wafer butterfly valve is a quarter-turn valve that uses a rotating disc to control fluid flow.
Basic Working Principle
- Disc parallel to flow = Fully open
- Disc perpendicular to flow = Fully closed
- Partial rotation = Flow regulation
The wafer design allows the valve to be installed between standard pipeline flanges without requiring threaded bolt holes in the valve body.
