KSB Group’s future-proof diaphragm valves for drinking water

Valves installed in ingesting water transport systems have to satisfy stringent demands, each when it comes to design and supplies employed.
To fulfill these necessities the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve sort collection, featuring threaded sockets, a stainless-steel body and a special drinking water diaphragm.
The physique is made from 1.4409, a material that is notably resistant to chlorinated water and suitable for ingesting water. To keep the fluid handled clear, the body is designed without lifeless volume, thus stopping deposits in the valve. Nominal sizes range from Rp 1/2”- 3”.
The confined and supported diaphragm maximises service life and is designed for a pressure of sixteen bar. It is made of high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics appropriate for drinking water functions (KTW-BWGL). The valves cover a temperature vary from -10 °C to +90 °C. This means the kind series can be highly appropriate for thermal disinfection.
Since the threaded stems for actuating the valves aren’t involved with the fluid handled, they will continue to deliver easy operation even after many years of use. The stem protection fitted prevents any external contamination and in addition serves to point the valve place. Closing pressure gauge 4 นิ้ว are minimised by a smooth-running thrust bearing.
