Its purpose is to prevent back-suction or back-flow of non-potable water into the public drinking water system. The valve covers a wide range of application possibilities, including use in printers, chemical and food industries, laboratories and medical technology. It is designed as a three pressure zone system with controllable pressure zones before and after the valve , with an intermediate pressure zone in between. Two isolation valves are also included and the valve is equipped with three ball valves for functional testing by pressure measurement.

Properties:

• Maximum working pressure: 10 bar
• Maximum working temperature: 65°C
• Connection size to the system: DN 20
