        Pneumatic Wafer Type Butterfly Valve (with Lining)

        Corrosion-Resistant Pneumatic Wafer Butterfly Valve | Designed for Highly Corrosive Media

        這 Pneumatic Wafer Type Butterfly Valve (with lining) is designed with advanced PTFE/PFA lining technology, making it ideal for industries where fluid control is critical and exposure to aggressive chemicals is common. Its innovative wafer design saves installation space while maintaining superior resistance to corrosion, making it perfect for applications such as acid pickling production lines, lithium battery electrolyte transportation, and chemical reactor feeding systems.

        Product Overview

        主要特點：

        • Exceptional Corrosion Resistance
          The valve body and butterfly plate are lined with polytetrafluoroethylene (PTFE), providing excellent resistance to aggressive chemicals such as 98% sulfuric acid 和 concentrated hydrochloric acid. This ensures the valve performs in the harshest industrial environments and offers a long lifespan without degradation from corrosive substances.

        • Temperature and Pressure Resistance
          The valve operates efficiently within a temperature range of -20°C to 150°C, making it suitable for both high and low-temperature environments. With a pressure rating of PN10 to PN16, the valve can handle demanding applications requiring high pressure.

        • Compact and Efficient Design
          Featuring a wafer design, this valve reduces the installation space required, making it ideal for environments with limited installation space. The wafer design also contributes to lower installation costs compared to traditional flanged valves.

        • Pneumatic Actuation
          The valve is driven by AT Series Pneumatic Actuators, available in both double-acting 和 spring return configurations. These actuators provide high reliability, quick response, and large output torque, making the valve perfect for automatic fluid control systems. The actuator’s gear and rack drive ensures durability and dependability over time.

        • Safety and Protection
          Fireproof and anti-static options are available for the valve, enhancing its safety in hazardous environments. Additionally, the valve stem is completely isolated from the media, preventing corrosion of the stem.
