The GEMÜ Tugela butterfly valve is particularly distinguished by its double-eccentric construction, which is why it is also designated as a high-performance butterfly valve and suitable for pressures up to 40 bar or temperatures up to 230 °C. The butterfly disc separates directly from the sealing seat when it opens, which reduces wear and thus increases service life. Thanks to the locking screw on the actuator flange, the gland packing can be retightened directly at the shaft, which sits in a carbon braid bearing, so that the butterfly valve can be serviced when installed. This, in turn, significantly reduces the maintenance requirements.

Double-eccentric design for easy opening and increased service life When constructing butterfly valves, a distinction is made between three main designs.

In a concentric design, such as the GEMÜ Victoria series, the pivot point is in the centre of the seat valve, i.e. the main seal is interrupted by the shaft.

In a simple eccentric construction, the main seal is offset to the shaft axis. There is no interruption over the entire 360° sealing circumference with this design.

In a double-eccentric design, the shaft axis is additionally, as the second eccentricity, moved out of the piping axis so that the shaft centre is slightly offset from the piping centre.

Further features of the GEMÜ R470 Tugela butterfly valve are the shaft blow-out protection as an additional safety measure in case the shaft breaks and the improved sealing due to an optimized disc design in spherical form. The GEMÜ R470 Tugela also has an antistatic spring for use in ATEX areas and a TFM seat ring which is particularly low-brittle and ensures reliable use in a wide temperature range.

The valve specialist GEMÜ is expanding its product range of industrial ball valves. Due to its multi-functional properties, the newly developed GEMÜ BB07 3/2-way ball valve family is suitable for the most varied areas of application.

A special version of the GEMÜ R480 Victoria butterfly valve series from Ingelfingen-based valve specialist GEMÜ is approved with immediate effect for the medium of oxygen.

When it comes to dewatering, Tsurumi is the go to brand. In Hall 6, the pump manufacturer presented the new KRDX explosion proof dewatering pump and the new LSC2.75S residue pump. The company also demonstrated how to get all construction gear on site onto the network: namely, amazingly simply with the Tsurumi Connect-Box.

The digitization of complex production facilities is a process that can last for years. IIoT platforms represent a smart solution here that is tailored to the respective customer. It is possible to start by collecting data from individual machines and gradually drive digitization forward.

NETZSCH Pumps & Systems has given the proven TORNADO T1 rotary lobe pump a facelift to increase customers’ added value further. This promises to reduce repair times by more than 40 percent and significantly improve energy efficiency. Existing systems can also be upgraded.

The GEMÜ 550 angle seat globe valve from the Ingelfingen-based valve specialist GEMÜ is now available with gas approval in accordance with DVGW (German Technical and Scientific Association for Gas and Water).
