Flowrates butterfly valves are designed to ensure absolute sealing and enhanced resistance, making them ideal for the most demanding industrial and marine environments. Thanks to their high-precision vulcanized lining, they provide comprehensive corrosion protection, extended lifespan, and maximum reliability, even under full pressure at end-of-line service. Vulcanized Coating Technology for Total Sealing 100% sealing on upper and lower shaft joints, achieved through a dual primary and secondary seal system. Vulcanized lining molded under 150-bar pressure, ensuring perfect adhesion and extreme durability. Full corrosion protection: The lining completely covers the valve body interior, preventing any interaction between the fluid and the valve material. No need for additional flange gaskets, as the lining extends beyond the flange faces, simplifying installation and improving sealing. Suitable for vacuum applications and high-velocity fluids: The lining is permanently fixed, preventing any deformation or aspiration into the pipeline. Long-Term Reliability and Mechanical Performance Zero deformation, zero lining detachment, even in extreme conditions. Minimal seat wear, extending service life up to 3 times compared to replaceable linings. Low torque operation, thanks to an optimized design that facilitates automation and reduces mechanical stress. Permanent dry shaft lubrication, ensuring extended component lifespan and smooth operation. Bidirectional flow stability, providing efficient and homogeneous fluid regulation.
