Valves put in in ingesting water transport techniques have to meet stringent calls for, both in phrases 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 series, featuring threaded sockets, a stainless-steel body and a special ingesting water diaphragm.
The body is made of 1.4409, a material that’s notably immune to chlorinated water and suitable for ingesting water. To maintain the fluid handled clear, the physique is designed without useless 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 strain of 16 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). The valves cover a temperature vary from -10 °C to +90 °C. This means the type sequence can also be highly appropriate for thermal disinfection.
Since เกจวัดแรงดันน้ำมันเครื่อง threaded stems for actuating the valves are not in contact with the fluid dealt with, they may continue to deliver smooth operation even after many years of use. The stem safety fitted prevents any exterior contamination and also serves to point the valve position. Closing torques are minimised by a smooth-running thrust bearing.
