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

Valves installed in consuming water transport methods have to satisfy stringent calls for, both when it comes to design and supplies employed.
To fulfill these necessities the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve sort collection, featuring threaded sockets, a stainless-steel body and a particular consuming water diaphragm.
Confidential is made of 1.4409, a material that’s significantly immune to chlorinated water and suitable for consuming water. To hold the fluid dealt with clear, the physique is designed with out dead 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 sixteen bar. It is made from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics suitable for consuming water applications (KTW-BWGL). The valves cowl a temperature range from -10 °C to +90 °C. This means the sort collection can also 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 continue to deliver smooth operation even after many years of use. The stem safety fitted prevents any external contamination and also serves to point the valve position. Closing torques are minimised by a smooth-running thrust bearing.
