Alfaidro Check valve is a Europa-type non-return valve made of random polypropylene in an opaque colour that prevents light from entering and hinders microbiological growth in the transported water, making it ideal for transporting drinking water.
PP-R 100 boasts high heat resistance and excellent chemical resistance. Check valves are an important component in hydraulic and air systems and it is that component which allows the water flow to only travel in one direction. The check valve is characterised by the total absence of metal components that are susceptible to wear and corrosion. It is connected to the circuit by socket welding and can be used in all civil and industrial water distribution and heating systems.
