Stainless Steel Disco Check Valve

The RV110 check valve is commonly referred to as a disco check valve. A special feature of this specific model is the four earthing lugs. The valve disc is connected to a pressure spring, ensuring that the RK110 closes automatically even at low pressure or backflow, thus preventing medium reflux. Disco check valves are particularly suitable for clean liquids and gases. The RV110 model is available in many material combinations, allowing it to be flexibly adapted and optimally adjusted to the respective application and purpose. We offer a wide selection of check valves manufactured from various materials and in many variable designs. Please contact our sales office for comprehensive and free advice on this topic. An overview of the many RV110 variants can be found under “Tech. Data” and in the data sheet under “Downloads”.
