Description
High-performance butterfly valve made from ductile iron with a double eccentric (offset) design, reducing seat wear and ensuring reliable sealing over a long service life. Double flanged body provides robust, leak-proof connections, ideal for critical applications in water, HVAC, and industrial systems. Gear-operated mechanism enables precise, low-torque operation for safe and smooth flow control. Rated PN16 for pressures up to 16 bar, suitable for medium-pressure pipelines with flanged ends for standardized, secure installation.
