VALVE specialist Gemü has redesigned its butterfly valves and now offers the Gemü R480 Victoria in wafer version.
According to the company, a team from the design, product management, quality management and production departments refined a number of technical specifications, while also further expanding 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 company said in a statement.
“The valve bodies are milled in one clamping position at our highly automated valve production facilities at Gemü Valves China. This allows precise shape and positional tolerances to be achieved. In addition, 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.
“Thanks to its flow-optimised and sleek disc design, the redesigned Gemü R480 Victoria butterfly valves achieve higher flow rate factors. This reduces the pressure loss, giving the butterfly valves greater energy efficiency.”
It added that the valves' constant compression on axes and shaft bearings mean that they provide savings in operating costs as they require a lower torque for operation. The PTFE-coated steel bushes in the axis and shaft area further reduce the torque, thereby helping to save costs.
The integration of an RFID chip means the new valves are prepared for Industry 4.0.
“With CONEXO, Gemü offers an RFID system architecture that enables clear identification of wearing parts, paperless maintenance and process documentation. The CONEXO app guides maintenance technicians through the fully customisable maintenance workflows step by step.”
The new Gemü R480 Victoria series is available in a wide range of nominal sizes, from DN 50 to DN 300.
