DN 250 Straight-Through Sewer Non-Return Valve

Product detailed description

The DN 250 straight-through sewer non-return valve prevents the backflow of sewage, rodents and odors inside sewer systems. It works automatically, so it closes automatically in the event of backflow. The lever is used only in the event of an emergency. When locked, water does not flow in any direction. In the event of clogging, it can be cleaned by unscrewing the four screws on the top of the valve and removing the cover. The non-return valve must be installed horizontally. The DN 250 straight-through sewer non-return valve is made of high-quality polypropylene (PP), which is resistant to aggressive chemicals and hot sewage (up to 95°C). The inside of the valve has a smooth surface that prevents dirt from settling. The seals are made of rubber (EPDM) with increased resistance to weathering and aging.
