Valves installed in ingesting water transport techniques have to satisfy stringent demands, both in terms of design and materials employed.
To fulfill these necessities the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve type collection, that includes threaded sockets, a stainless-steel body and a special drinking water diaphragm.
The physique is made from 1.4409, a cloth that’s notably immune to chlorinated water and appropriate for consuming water. To maintain the fluid dealt with clean, the body is designed without lifeless quantity, 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 consuming water applications (KTW-BWGL). เกจวัดถังแก๊ส cover a temperature range from -10 °C to +90 °C. This means the sort series can also be extremely suitable for thermal disinfection.
Since the threaded stems for actuating the valves usually are not involved with the fluid handled, they will continue to deliver clean operation even after many 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.
