DK66-PVC Pneumatic UPVC Double Union Flange Ball Valve – High Integrity & Serviceable
The DK66-PVC Pneumatic UPVC Ball Valve is a specialized solution for automated control of highly corrosive fluids in critical pipelines. It offers superior chemical resistance through its UPVC construction. The unique Double Union Flange connection provides the stability and integrity of a flanged mount, while allowing the valve body to be quickly disconnected and removed from the line for maintenance—a crucial advantage. Paired with a pneumatic actuator, it delivers rapid, quarter-turn shutoff for safety and efficiency in water and chemical processing systems requiring both stability and serviceability.
Size Range: DN15-DN100
Material: UPVC, CPVC,PPH,PVDF
Connection Standard: GB / ANSI / JIS /DIN
Features
A pneumatic UPVC ball valve featuring a highly secure Double Union Flange connection, designed for fast, automated, corrosion-resistant shutoff and easy inline serviceability.
✅Hybrid Connection (Double Union Flange): This unique end connection combines the high-integrity, secure mounting of a flange with the rapid disassembly advantage of a union, allowing the valve to be removed for maintenance without disturbing fixed pipeline alignment.
✅Superior Corrosion Immunity (UPVC): Constructed entirely from UPVC, the valve is impervious to a wide range of aggressive media, ensuring long-term reliability in chemical processing, water treatment, and corrosive fluid transfer.
✅Rapid Pneumatic Automation: A pneumatic actuator provides immediate, high-speed, quarter-turn response, essential for safety shutoff, fast batch cycling, and critical process isolation.
✅Low Maintenance Downtime: The union design allows the central valve body to be quickly unscrewed and serviced (seal/seat replacement) without cutting the pipe or unbolting the fixed flange ends.
✅High Flow Capacity: The full-bore ball valve design minimizes pressure drop and energy loss, optimizing fluid transfer efficiency in high-volume utility and industrial lines.
