What is a Wafer Butterfly Valve? Complete Guide for Industrial Buyers
A wafer butterfly valve is one of the most widely used quarter-turn valves in industrial piping systems. It uses a circular disc that rotates 90° to start, stop, or regulate flow, and its compact wafer design makes it ideal for installations where space is limited.
Key Advantages
Wafer butterfly valves are lightweight, cost-effective, and easy to install between flanges. They offer fast operation, reliable shutoff, and work across a wide range of pressures and temperatures, making them a top choice for water treatment, HVAC, chemical processing, and general industrial applications.
