A pneumatic butterfly valve is an industrial flow control device actuated by compressed air to regulate or isolate media in pipelines. Constructed from materials like stainless steel, cast iron, or PVC, these valves typically adhere to standards such as ANSI/ASME B16.5 and API 609 for dimensional and performance consistency.
Ensure pneumatic actuators are sealed against moisture and dust to prevent malfunction. Regularly inspect seals and disc alignment during scheduled maintenance cycles. Replace gaskets and diaphragms periodically to avoid leakage, especially when operating near maximum temperature or pressure limits.
