Check valve / storm gate valve STAUFIX BASIC DN150 d160, TYPE-2, two mechanical check flaps, without rodent protection, with emergency closure, for wastewater without fecal matter, plastic, black color 73150

Non-return valve for drainage system protection

This Staufix Basic DN150 dual-flap non-return valve provides reliable protection against sewage backflow in systems without solids. Its simple construction and solid design made of fiber-reinforced plastic guarantee long-lasting protection and easy installation. The valve is particularly useful when the drain point is below the flooding level or as a central protection on horizontal sections of the drainage system.

Functionality and construction

A key feature of this valve is the presence of two mechanical check flaps. One of them automatically closes during reverse flow, while the other serves as an emergency manual shut-off – providing additional control over the flow and the ability to react quickly in emergency situations. The nominal diameter of DN150 and the outer diameter of 160 mm make the valve compatible with most standard drainage systems. The design allows for easy maintenance and cleaning without the need for specialized tools.

Application and benefits

The Staufix Basic valve is widely used in residential, commercial and public buildings. It is an ideal solution for both new installations and modernization of existing drainage systems. Thanks to its design, it provides effective protection against flooding caused by sewage backflow, which translates into safety and comfort of use. Additionally, the lack of the need for tools during maintenance significantly simplifies the process of keeping the valve in optimal technical condition. It should be remembered that the valve is intended only for wastewater without solids and should not be used in drinking water or central heating installations.
