KSB Group’s future-proof diaphragm valves for ingesting water

Valves put in in ingesting water transport techniques have to satisfy stringent calls for, each when it comes to design and materials employed.
To fulfill diaphragm seal ’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve type collection, that includes threaded sockets, a stainless-steel physique and a special consuming water diaphragm.
The physique is manufactured from 1.4409, a cloth that’s particularly immune to chlorinated water and appropriate for drinking water. To keep the fluid handled clear, the body is designed with out dead quantity, thus stopping deposits in the valve. Nominal sizes range from Rp 1/2”- 3”.
diaphragm seal confined and supported diaphragm maximises service life and is designed for a pressure of sixteen bar. It is made of high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics appropriate for ingesting water purposes (KTW-BWGL). The valves cowl a temperature range from -10 °C to +90 °C. This means the kind sequence can be extremely appropriate for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in contact with the fluid handled, they may continue to deliver smooth operation even after many years of use. The stem protection fitted prevents any exterior contamination and likewise serves to indicate the valve position. Closing torques are minimised by a smooth-running thrust bearing.
