Valves installed in drinking water transport techniques have to meet stringent calls for, each by method of design and materials employed.
To satisfy 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 physique and a special ingesting water diaphragm.
The physique is manufactured from 1.4409, a material that is notably proof against chlorinated water and appropriate for ingesting water. To maintain the fluid dealt with clean, the body is designed with out useless volume, thus preventing deposits in the valve. Nominal sizes vary from Rp 1/2”- 3”.
เกจวัดแรงดันอากาศ confined and supported diaphragm maximises service life and is designed for a pressure of 16 bar. It is manufactured from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics suitable for drinking water functions (KTW-BWGL). The valves cover a temperature vary from -10 °C to +90 °C. This means the sort series is also extremely appropriate for thermal disinfection.
Since the threaded stems for actuating the valves are not involved with the fluid handled, they will proceed to ship clean operation even after many years of use. The stem safety fitted prevents any exterior contamination and in addition serves to indicate the valve place. Closing torques are minimised by a smooth-running thrust bearing.
