Valves installed in ingesting water transport systems have to satisfy stringent calls for, both by means 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 sort series, featuring threaded sockets, a stainless-steel body and a special ingesting water diaphragm.
The physique is made of 1.4409, a fabric that is particularly immune to chlorinated water and suitable for consuming water. To maintain the fluid handled clean, the body is designed without lifeless volume, thus stopping 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 stress of 16 bar. It is made from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics appropriate for consuming water functions (KTW-BWGL). The valves cowl a temperature range from -10 °C to +90 °C. pressure gauge น้ำ means the type collection can be extremely suitable for thermal disinfection.
Since the threaded stems for actuating the valves are not involved with the fluid dealt with, they may proceed to ship clean operation even after a few years of use. The stem safety fitted prevents any external contamination and in addition serves to indicate the valve position. Closing torques are minimised by a smooth-running thrust bearing.
