Product Detail

Product Overview

The pneumatic stainless steel flange butterfly valve is one of the most commonly used valves in industrial pipeline systems. The pneumatic wafer soft-seal butterfly valve features compact size, less material consumption and light weight. It is more cost-effective than other valve types, especially for large-diameter specifications. Driven by a pneumatic actuator, the valve can be fully opened and closed with a 90° rotation for fast and simple operation. It delivers excellent fluid control performance. When fully open, the thickness of the butterfly disc becomes the only flow resistance, ensuring minimum pressure loss and smooth fluid transportation.
