Valves put in in drinking water transport systems have to satisfy stringent calls for, both in phrases of design and supplies employed.
To satisfy these necessities the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve kind series, featuring threaded sockets, a stainless-steel physique and a particular ingesting water diaphragm.
The physique is manufactured from 1.4409, a fabric that is particularly immune to chlorinated water and suitable for ingesting water. To keep the fluid handled clean, the body is designed with out dead quantity, 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 stress of sixteen bar. It is manufactured from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s necessities on plastics suitable for drinking water functions (KTW-BWGL). The valves cowl a temperature vary from -10 °C to +90 °C. ตัววัดแรงดันน้ำ means the type collection is also extremely appropriate for thermal disinfection.
Since the threaded stems for actuating the valves are not in contact with the fluid dealt with, they may continue to deliver easy operation even after a few years of use. The stem safety fitted prevents any exterior contamination and also serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
