        Pneumatic Wafer Type Butterfly Valve (with Lining)

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

        The 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

        Key Features:

        • 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 and 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 and 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.

        DELCO Wafer Type Butterfly Valve

        Applications:

        • Chemical Industry: Ideal for applications involving corrosive chemicals and aggressive media, such as acid pickling and chemical reactors. The corrosion-resistant lining ensures long-term reliable operation.

        • Lithium Battery Production: Used in systems that transport lithium battery electrolytes, providing corrosion resistance to ensure safe transportation and handling of sensitive materials.

        • Water Treatment: Widely used in both wastewater treatment and clean water systems, ensuring effective fluid management in critical environments.

        • Food and Beverage: Suitable for hygienic applications requiring precise fluid flow control, ensuring hygiene and operational efficiency in food processing.

        Technical Specifications:

        • Nominal Pressure: PN10 ~ PN16

        • Pressure Resistance: Can withstand 1.6 MPa for shell tests and 0.6 MPa for sealing tests.

        • Temperature Range: -20°C to 150°C

        • Material:

          • Valve Body: Grey Cast Iron, Carbon Steel, or Stainless Steel

          • Valve Ball and O-Ring: Copper Base Powder Metallurgy

        Structural Design Features:

        • Three-Eccentric Sealing Structure: The valve utilizes a combination of metal and fluoroplastic for seat sealing. This ensures smooth operation with minimal friction, reliable sealing, and extended lifespan. The valve can handle high temperatures and pressure without compromising its performance.

        • High-Precision Butterfly Plate: The butterfly plate is made of a multi-layer composite material that reduces friction and ensures a perfect seal even under high pressure and high-temperature conditions. This provides reliable and durable performance throughout the valve’s lifecycle.

        • Pneumatic Actuator: The valve is equipped with AT Series Pneumatic Actuators, providing large output torque and allowing for precise fluid control. These actuators are designed according to NAMUR standards, ensuring easy integration with solenoid valves, positioners, and limit switches for enhanced automation.

        • Lightweight and Compact Design: The pneumatic wafer valve is lightweight, compact, and easy to install, making it especially useful for applications where space is constrained. The compact design reduces installation time and labor costs.
