Valves installed in ingesting water transport systems have to satisfy stringent calls for, both by means 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 kind collection, that includes threaded sockets, a stainless-steel body and a particular ingesting water diaphragm.
The physique is made of 1.4409, a fabric that’s notably proof against chlorinated water and appropriate for consuming water. To maintain the fluid dealt with clear, the physique is designed without 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 stress of sixteen bar. It is manufactured from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics appropriate for drinking water applications (KTW-BWGL). เกจปรับแรงดันแก๊ส cover a temperature vary from -10 °C to +90 °C. This means the type series is also highly suitable for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in touch with the fluid dealt with, they may proceed to deliver easy operation even after many years of use. The stem safety fitted prevents any exterior contamination and in addition serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
