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

Valves installed 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 collection, that includes threaded sockets, a stainless-steel physique and a special drinking water diaphragm.
The body is made from 1.4409, a material that’s particularly resistant to chlorinated water and suitable for drinking water. To maintain the fluid dealt with clear, the body is designed with out useless volume, thus stopping deposits within the valve. Nominal sizes range from Rp 1/2”- 3”.
The confined and supported diaphragm maximises service life and is designed for a strain of 16 bar. It is made of high-quality elastomer (EPDM/W270) and meets the German Environment Agency’s necessities on plastics suitable for consuming water purposes (KTW-BWGL). The valves cover a temperature range from -10 °C to +90 °C. This means the kind series is also highly suitable for thermal disinfection.
Since pressure gauge วัด แรง ดัน threaded stems for actuating the valves are not involved with the fluid handled, they may proceed to deliver easy operation even after a few years of use. The stem safety fitted prevents any external contamination and likewise serves to point the valve position. Closing torques are minimised by a smooth-running thrust bearing.
