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

Valves installed in drinking water transport methods have to satisfy stringent demands, both by means of design and materials employed.
To satisfy these requirements the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve type series, featuring threaded sockets, a stainless-steel body and a special drinking water diaphragm.
The body is made from 1.4409, a fabric that is notably proof against chlorinated water and appropriate for drinking water. To maintain the fluid dealt with clean, the body is designed without useless quantity, thus stopping deposits within the valve. Nominal sizes range from Rp 1/2”- 3”.
Best confined and supported diaphragm maximises service life and is designed for a pressure of sixteen bar. It is manufactured from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics suitable for consuming water applications (KTW-BWGL). The valves cowl a temperature vary from -10 °C to +90 °C. Ingredients means the kind collection can be extremely appropriate for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in touch with the fluid handled, they will continue to ship clean operation even after a few years of use. The stem protection fitted prevents any exterior contamination and also serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
