A future-proof diaphragm valve for drinking water
Valves installed in drinking-water transport systems have to meet stringent demands, both in terms of design and materials employed. To satisfy these requirements, this company has launched its SISTO-16RGAMaXX diaphragm valve series, featuring threaded sockets, a stainless-steel body and a special drinking-water diaphragm. The body is made of EN 1.4409 stainless steel, a material that is particularly resistant to chlorinated water and suitable for drinking water. The body is designed without dead volume, thus preventing deposits in the valve. Nominal sizes range from Rp 1/2 to 3 in. The confined and supported diaphragm maximizes service life and is designed for a pressure of 16 bars. It is made of high-quality elastomer (EPDM/W270). The valves cover a temperature range from –10 to 90°C, which makes the series suitable for thermal disinfection. — Sisto Armaturen S.A., Luxemburg, part of KSB SE & Co. KGaA
