A wafer butterfly valve is a compact industrial valve designed for efficient flow control in pipeline systems. The valve body is installed between two pipeline flanges, creating a lightweight and space-saving solution for water treatment, HVAC systems, chemical processing, and industrial utility applications.
The wafer butterfly valve is widely used because of its simple structure, reliable sealing performance, easy installation, and cost-effective operation.
🔍 What Is a Wafer Butterfly Valve?
Structure and Design
A wafer butterfly valve generally includes:
- Slim valve body
- Rotating valve disc
- Sealing seat
- Stem shaft
