Valves installed in drinking water transport techniques have to fulfill stringent calls for, each when it comes to design and materials employed.
To satisfy pressure gauge วัด แรง ดัน ’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve sort collection, featuring threaded sockets, a stainless-steel physique and a special ingesting water diaphragm.
The body is made from 1.4409, a fabric that is particularly immune to chlorinated water and suitable for consuming water. To hold the fluid handled clean, the body is designed with out dead volume, thus stopping deposits in the valve. Nominal sizes vary 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 requirements on plastics suitable for ingesting water functions (KTW-BWGL). The valves cowl a temperature range from -10 °C to +90 °C. This means the kind sequence can additionally be extremely suitable for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in touch with the fluid dealt with, they will proceed to deliver smooth operation even after a few years of use. The stem safety fitted prevents any exterior contamination and also serves to point the valve place. Closing torques are minimised by a smooth-running thrust bearing.
