Valves installed in drinking water transport methods have to fulfill stringent calls for, both in phrases of design and materials employed.
To satisfy these necessities the KSB Group’s SISTO Armaturen S.A. in Luxembourg has launched its SISTO-16RGAMaXX diaphragm valve sort collection, featuring threaded sockets, a stainless-steel body and a particular drinking water diaphragm.
The physique is manufactured from 1.4409, a cloth that is particularly proof against chlorinated water and suitable for consuming water. To maintain the fluid handled clean, the body is designed with out lifeless volume, thus preventing deposits within the valve. Nominal sizes vary from Rp 1/2”- 3”.
เครื่องวัดแรงดันเกจที่นิยมใช้ 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 necessities on plastics suitable for consuming water purposes (KTW-BWGL). The valves cowl a temperature vary from -10 °C to +90 °C. This means the sort collection can be highly suitable for thermal disinfection.
Since the threaded stems for actuating the valves aren’t in touch with the fluid dealt with, they’ll proceed to ship smooth operation even after a few years of use. หลักการทำงานของเกจ์วัดแก๊ส fitted prevents any exterior contamination and in addition serves to indicate the valve position. Closing torques are minimised by a smooth-running thrust bearing.
