Valve specialist GEMÜ has redesigned its tried-and-tested butterfly valves and now offers the GEMÜ R480 Victoria in wafer version.
In redesigning the GEMÜ R480 Victoria series, a specialized team from the design, product management, quality management, and production departments has refined a multitude of technical specifications, while also further expanding GEMÜ’s manufacturing capabilities. Thanks to investments in in-house machining and coating expertise, GEMÜ now has even greater control over production processes that are essential to quality.
The valve bodies are milled in one clamping position at its highly automated valve production facilities at GEMÜ Valves China. This allows the precise shape and positional tolerances to be achieved. Also, GEMÜ has greater control over butterfly valve quality as they are machined in-house. A further advantage of in-house manufacturing is the fact that the delivery times are more flexible, meaning that availability is better controlled.
Another feature of the GEMÜ R480 Victoria series is the technical optimization of their liners for improved tightness. The inclusion of additional material in the seat, axes, and shaft areas as well as a groove in the flow direction for positive liner fixing improves the butterfly valves’ sealing and resistance to slipping. A fixed point for the liner on the valve body makes it easy to change liners and to read the liner material, even when installed.
