Victoria butterfly valve 480, 481, 487

The GEMÜ Victoria butterfly valves types 480, 481 and 487 are centric, soft-seated industrial valves for demanding applications in water, chemical and power engineering. With their robust elastomer shut-off seal, high-quality metal construction and available actuator variants (manual, pneumatic, electric), they offer a durable, reliable sealing and versatile solution for industrial piping systems. The series is available in wafer, lug and U-type versions and covers nominal sizes up to DN 600 – ideal for modular systems, SKIDs, supply technology and the process industry.
