DK66-PL Pneumatic UPVC Double Union Ball Valve - Fast Corrosion-Resistant Shutoff
The DK66-PL Pneumatic Plastic Ball Valve is designed for fast, automated on/off control in corrosive environments. Constructed from durable UPVC/PVC plastic, it offers excellent resistance to most acids, alkalis, and saline solutions. Coupled with a pneumatic actuator, it delivers rapid, quarter-turn isolation for quick process cycling. The key feature is the double union connection, which allows the valve body to be quickly and easily removed from the pipeline for service without cutting the pipe, minimizing maintenance downtime.
Features
A pneumatic plastic double union ball valve offering corrosion-resistant, high-speed automated shutoff and superior maintenance convenience for chemical and water applications.
✅Corrosion Immunity (UPVC/PVC): The plastic construction ensures long service life and reliable performance when handling highly corrosive media, such as chemical dosing agents, strong acids, or seawater.
✅Double Union for Easy Maintenance: The double union ends allow the operator to quickly unscrew the connections and remove the valve body for seal replacement or cleaning without disturbing the pipe structure, significantly reducing downtime.
✅Rapid Pneumatic Automation: The pneumatic actuator provides immediate, high-speed, quarter-turn response, ideal for safety shutoff or high-frequency cycling required in automated systems.
✅Economical and Lightweight: The plastic body offers a cost-effective and lightweight alternative to heavy metal valves without compromising corrosion resistance in low-to-medium pressure applications.
✅Bubble-Tight Isolation: The ball valve design ensures positive, complete flow isolation when fully closed, providing reliable shutoff for both water and chemical process lines.
