Engineered for reliable flow isolation and modulation in chemically challenging environments, this valve integrates a robust butterfly mechanism with a resilient polymer lining. The critical components, including the body and wetted areas, are internally shielded using high-grade fluoroplastics like PTFE, FEP (F46), or PFA. This lining creates an impermeable barrier against aggressive and acidic media, dramatically extending the valve’s service life compared to standard metal valves.
The valve is operated by an industrial-grade electric actuator, which carries an IP67 rating for superior weather resistance and reliable performance in demanding outdoor or washdown conditions. With available control modes ranging from simple on/off switching to precise proportional control, this unit provides flexible and automated process management across flow sizes from DN50 to DN600.
Features & Benefits
Maximum Chemical Immunity: The comprehensive Fluorine Lining ensures long-term resistance when handling highly corrosive liquids, gases, and hazardous substances, protecting the body materials (e.g., Ductile Iron, WCB) from direct contact.
Versatile Automated Control: Features an electric actuator capable of both on/off operation for isolation tasks and proportional control for accurate throttling and modulating flow rates.
Global Specification Compliance: Designed for seamless integration into diverse piping systems, supporting international pressure ratings including PN10/PN16, ANSI150, and JIS standards.
Environmental Durability: The actuator’s IP67 protection class ensures the electrical components are fully protected against dust ingress and temporary water immersion, guaranteeing reliability in harsh environments.
Wide Temperature Range: Equipped with PTFE seals that maintain performance across temperatures ranging from $-25\,^\circ\text{C}$ to $150\,^\circ\text{C}$.
