Valves put in in drinking water transport systems have to meet stringent calls for, each by means of design and supplies employed.
To satisfy these requirements the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve sort series, featuring threaded sockets, a stainless-steel physique and a special drinking water diaphragm.
The physique is made 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 dead volume, thus preventing deposits in the valve. Nominal sizes vary from Rp 1/2”- 3”.
The 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 necessities on plastics appropriate for consuming water applications (KTW-BWGL). The valves cover a temperature vary from -10 °C to +90 °C. This means the kind collection can be highly suitable for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in touch with the fluid handled, they may continue to ship clean operation even after a few years of use. เกจแรงดัน fitted prevents any exterior contamination and likewise serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
