AYVAZ KVA-8 Gear Operated Butterfly Valve PN16 DN250

Low-torque quarter-turn control for high-pressure industrial lines.

AYVAZ KVA-8 Gear Operated Butterfly Valve provides controlled flow management in high-pressure lines. In addition, its DN250 nominal diameter and PN16 pressure class deliver dependable performance across industrial plants. The lug type connection design, moreover, allows maintenance work without removing the valve from the pipeline.

A gear reducer mechanism keeps manual open-close operations at minimum torque. The body is GG25 cast iron, while the disc uses GGG40.3 nickel-plated ductile iron and the stem is AISI 420 stainless steel, therefore offering strong corrosion resistance. H-EPDM seals nearly eliminate liquid leakage, as a result sealing reliably up to a maximum working temperature of 130°C in steam and hot water lines.
