Valves installed in consuming water transport methods have to meet stringent calls for, both when it comes to design and materials employed.
To fulfill spmk700 ’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve kind collection, featuring threaded sockets, a stainless-steel physique and a special drinking water diaphragm.
The physique is made from 1.4409, a cloth that’s significantly resistant to chlorinated water and appropriate for ingesting water. To keep the fluid dealt with clean, the physique is designed with out useless volume, thus stopping 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 pressure of 16 bar. It is manufactured from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics suitable for consuming water functions (KTW-BWGL). The valves cowl a temperature range from -10 °C to +90 °C. This means the type series can be highly suitable for thermal disinfection.
Since the threaded stems for actuating the valves are not in contact with the fluid handled, they may proceed to deliver clean operation even after many years of use. The stem protection fitted prevents any exterior contamination and also serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
