Valves installed in consuming water transport methods have to fulfill stringent calls for, both when it comes to design and materials employed.
To satisfy these requirements the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve sort sequence, featuring threaded sockets, a stainless-steel physique and a particular ingesting water diaphragm.
The body is manufactured from 1.4409, a cloth that’s significantly proof against chlorinated water and suitable for consuming water. To maintain the fluid dealt with clean, the body is designed without lifeless volume, thus preventing 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 strain of sixteen bar. It is made from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s necessities on plastics appropriate for drinking water applications (KTW-BWGL). เกจวัดแรงดันไฟฟ้า cowl a temperature range from -10 °C to +90 °C. This means the sort series is also highly suitable for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in contact with the fluid dealt with, they may continue to deliver smooth operation even after a few years of use. The stem protection fitted prevents any external contamination and likewise serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
