The VATTEN pneumatic semi-lined butterfly valve is designed for use with acid and alkali-resistant media, making it ideal for applications in industries like chemical processing and environmental protection. It features a PTFE sealing material, offering excellent corrosion resistance to protect against the destructive effects of acids, alkalis, and other aggressive chemicals, ensuring long-term and stable operation.
The valve disc is available in a variety of materials, allowing for customization to meet the specific requirements of different media and operating conditions. Whether dealing with highly corrosive substances or applications under extreme temperature and pressure conditions, the VATTEN pneumatic semi-lined butterfly valve provides a reliable solution.
Additionally, the pneumatic actuation ensures flexibility and efficiency in operation, making it well-suited for automated control systems. This reduces the risk of manual errors and enhances the overall efficiency of the system.

The pneumatic actuator is made of double-acting aluminum alloy, and it is recommended to use a gas source pressure of 5-7kg.
