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

Valves put in in drinking water transport techniques have to fulfill stringent demands, each when it comes to design and supplies employed.
To satisfy these requirements the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve kind series, that includes threaded sockets, a stainless-steel physique and a particular consuming water diaphragm.
The body is manufactured from 1.4409, a material that’s significantly resistant to chlorinated water and appropriate for consuming water. To maintain ไดอะแฟรม ซีล dealt with clean, the physique is designed without dead quantity, thus stopping deposits in the valve. Nominal sizes range from Rp 1/2”- 3”.
The confined and supported diaphragm maximises service life and is designed for a pressure of sixteen bar. It is manufactured from high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s necessities on plastics suitable for consuming water purposes (KTW-BWGL). The valves cowl a temperature range from -10 °C to +90 °C. This means the kind series can be extremely appropriate for thermal disinfection.
Since the threaded stems for actuating the valves are not in contact with the fluid handled, they will proceed to deliver smooth operation even after a few years of use. The stem protection fitted prevents any external contamination and in addition serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
