The pneumatic actuator vacuum butterfly valve is an advanced flow control device designed for high-performance vacuum systems and industrial automation. Powered by compressed air, the valve integrates a precision-engineered pneumatic actuator that ensures smooth, accurate, and reliable operation even under low-pressure or vacuum environments.
At WUXI XINMING AUTO-CONTROL VALVES INDUSTRY CO., LTD., our pneumatic actuator vacuum butterfly valve is manufactured with premium stainless steel or aluminum alloy components, ensuring corrosion resistance and leak-free performance. The valve's compact design and lightweight construction make it ideal for space-limited piping systems, while its fast-acting actuator allows for precise control in critical vacuum applications.
