Pack of 2 check valves DN 150 mm, galvanised steel, automatic check valve with sealing rubber, insert for ventilation channels in ventilation pipes

PACKAGE AND SIZE - Our package contains 2 pieces DN 150 check valves with a diameter of 150mm, length of 88mm and thickness of 0.5mm. The non-return valve prevents the backflow of exhaust air and blocks the cold, humid outdoor air so it does not enter the living space. The flap opens when the fan blows the exhaust air outward and closes automatically as soon as the airflow stops. This increases the energy efficiency of the ventilation system and improves air quality
Product material: the valve body is made of galvanized steel, while the valve itself is made of aluminum. The shaft and spring are made of stainless steel. These materials are characterized by high hardness and heat resistance and are resistant to weakly corrosive liquids such as air and vapors. A rubber ring ensures the extractor's check valve stays closed and silently shuts off when not in use, increasing stability and reliability
EASY INSTALLATION The check valve opens and closes automatically, allowing airflow to flow in one direction. When installing a check valve 150, the flaps open only in the direction of the exhaust air. The 150mm channel check valve is ideally installed horizontally and fully inserted into the channel. It is also suitable for vertical installation and is perfect for renovating ventilation systems that do not have a check valve extractor hood
Effective Noise Reduction The internal rubber sealing ring of the check valve ensures better sealing and noise reduction. This ensures that the DN 150 check valve is secured and sealed in the channel. The check valve can be inserted directly into non-flexible metal or plastic pipes. However, for flexible pipes, steel hose clamps should be used to fix the check valve
Wide range of applications: check valves are suitable for round channels with an inner diameter of 150mm and fit all air supply and exhaust systems, such as air conditioners, dryers, extractor hoods, heating systems and ventilation systems in homes, retail and industry. Especially suitable for use with exhaust fans, bathroom fans, fans and attic fans
