Non-return valve Staufix Siphon DN50 with siphon 73052

Non-return valve for effective installation protection

The Staufix Siphon DN50 non-return valve is a reliable solution to protect installations from the effects of sewage backflow. Equipped with two mechanical check valves, it provides effective protection against flooding, and also allows for emergency manual shut-off – useful in situations requiring quick intervention. The siphon design means the valve is ready to be installed as a washing machine or dishwasher connection.

The Staufix Siphon valve has been designed with ease of use and maintenance in mind. Its construction allows quick access to the interior for cleaning without the need for specialized tools. The material used – plastic – guarantees corrosion resistance and long-term reliability.

Construction and application

The valve combines the function of protection against sewage backflow with ease of use. Thanks to the DN50 push-fit connections, installation is simple and quick, both in new and modernized installations. The 90-degree siphon bend provides optimal flow and minimizes the risk of sediment build-up. The rigid siphon further increases the stability of the structure.

The valve has a wide range of applications:

• Flood protection: Ideal for protecting rooms from the effects of sewage backflow from the sewer system.
• Appliance connections: Excellent as an installation element for connecting a washing machine, dishwasher or other appliances generating non-fecal wastewater.
• Installation modernization: The possibility of installation in existing pipe runs makes it easier to modernize older sanitary installations.
• Domestic and industrial installations: It will work both in residential buildings and in public utility buildings or industrial plants.
