Valves put in in drinking water transport methods have to satisfy stringent calls for, each 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 kind sequence, that includes threaded sockets, a stainless-steel body and a particular drinking water diaphragm.
The body is made from 1.4409, a material that’s significantly resistant to chlorinated water and suitable for ingesting water. To hold the fluid handled clear, the body is designed with out useless volume, thus preventing deposits within 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 16 bar. It is made of high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s necessities on plastics suitable for drinking water functions (KTW-BWGL). เกจวัดแรงดันแก๊สอาร์กอน cowl a temperature vary from -10 °C to +90 °C. This means the type sequence can additionally be extremely appropriate for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in touch with the fluid handled, they will proceed to ship easy operation even after a few years of use. The stem protection fitted prevents any exterior contamination and in addition serves to indicate the valve position. Closing torques are minimised by a smooth-running thrust bearing.
