Valves put in in ingesting water transport methods have to meet stringent demands, each when it comes to 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 sequence, that includes threaded sockets, a stainless-steel body and a special ingesting water diaphragm.
The physique is manufactured from 1.4409, a cloth that is notably resistant to chlorinated water and appropriate for ingesting water. To keep the fluid dealt with clean, the physique is designed without lifeless quantity, 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 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 ingesting water applications (KTW-BWGL). The valves cowl a temperature range from -10 °C to +90 °C. This means the type series can be extremely suitable for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in contact with the fluid dealt with, they may proceed to ship smooth operation even after a few years of use. The stem safety fitted prevents any exterior contamination and also serves to indicate the valve position. Closing เกจวัดแรงดันสูง are minimised by a smooth-running thrust bearing.
