SISTO Armaturen introduces its new SISTO-16RGAMaXX diaphragm valve type series

To satisfy these requirements the KSB Group’s SISTO Armaturen S.A. in Luxemburg has launched its SISTO-16RGAMaXX diaphragm valve type series, featuring threaded sockets, a stainless steel body and a special drinking water diaphragm.

The body is made of 1.4409, a material that is particularly resistant to chlorinated water and suitable for drinking water. To keep the fluid handled clean, the body is designed without dead volume, thus preventing deposits in the valve. Nominal sizes range from Rp 1/2“ to 3“.

The confined and supported diaphragm maximises service life and is designed for a pressure of 16 bar. It is made of high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s requirements on plastics suitable for drinking water applications (KTW-BWGL). The valves cover a temperature range from -10 °C to +90 °C. This means the type series is also highly suitable for thermal disinfection.

Since the threaded stems for actuating the valves are not in contact with the fluid handled, they will continue to be smooth to operate even after many years of use. The stem protection fitted prevents any external contamination and also serves to indicate the valve position. Closing torques are minimised by a smooth-running thrust bearing.
