Backflow valve for wastewater protection

This Staufix two-flap backflow valve is a reliable protection for the sewage system against the effects of wastewater backflow during heavy rainfall or network failures. It is designed for use in systems draining wastewater without fecal matter, providing effective protection for both installers and end-users. The construction with two mechanical self-closing flaps guarantees tightness and minimizes the risk of flooding.

Design and functionality

The valve is made of durable plastic reinforced with fiber, which ensures its long-term operation and corrosion resistance. Its simple construction facilitates installation and maintenance, and the ability to quickly clean without tools translates into time and cost savings. In addition, one of the flaps is made of stainless steel, which is an effective barrier against rodents, preventing them from entering the sewage system. The valve also has an emergency manual shut-off function, allowing for quick intervention when it is necessary to cut off the wastewater supply.

Application and compliance with standards

The Staufix valve finds wide application in residential, commercial buildings and wastewater drainage systems from laundries, showers, bathtubs or floor drains. It is ideal for both new installations and modernization of existing sewage systems. It meets the requirements of EN 13564 standard, which confirms its high quality and safety of use. Thanks to the nominal diameter of DN 100 and the outer diameter of 110 mm, it is compatible with most standard sewage pipes with similar parameters.
