Valves installed in drinking water transport techniques have to satisfy stringent calls for, both when it comes to design and supplies employed.
To fulfill these necessities the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve type collection, featuring threaded sockets, a stainless-steel body and a special ingesting water diaphragm.
The body is manufactured from 1.4409, a cloth that is notably resistant to chlorinated water and suitable for consuming water. To maintain the fluid dealt with clear, the body is designed without dead volume, thus preventing deposits within the valve. Nominal sizes vary from Rp 1/2”- 3”.
The confined and supported diaphragm maximises service life and is designed for a strain of sixteen bar. It is made from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics suitable for ingesting water purposes (KTW-BWGL). The valves cover a temperature vary from -10 °C to +90 °C. This means the type sequence is also highly suitable for thermal disinfection.
Since the threaded stems for actuating the valves are not involved with the fluid dealt with, they’ll continue to deliver easy operation even after a few years of use. The stem protection fitted prevents any exterior contamination and likewise serves to indicate the valve position. Closing เพรสเชอร์เกจคือ are minimised by a smooth-running thrust bearing.
