GEMÜ reveals its latest generation of soft seated butterfly valves

Valve specialist GEMÜ has redesigned its butterfly valves and now offers the GEMÜ R480 Victoria in a wafer version.
A specialised team has refined a multitude of technical specifications, while further expanding GEMÜ's manufacturing capabilities.
The valve bodies are milled in one clamping position at GEMÜ Valves China’s automated valve production facilities.
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.
The redesigned GEMÜ R480 Victoria butterfly valves achieves higher flow rate factors.
This reduces the pressure loss, giving the butterfly valves greater energy efficiency.
The valves' constant compression on axes and shaft bearings mean that they provide great savings in operating costs as they require a lower torque for operation.
Furthermore, the PTFE-coated steel bushes in the axis and shaft area further reduce the torque, thereby helping to save costs.
The valves’ layer thickness of at least 250 µm ensures consistent corrosion protection in accordance with ISO 12944-6 C5M, even in the liner area.
The use of the whirl sintering method considerably improves the adhesion of the coating to the metal when compared to static powder coating.
