The micro-resistance slow-closing check valve, also known as a non-return valve, is designed to prevent the reverse flow of media in pipelines. The opening and closing components rely on the flow and force of the media to open or close on their own. It is mainly used in pipelines where media flow in a single direction is required, allowing the media to flow in only one direction to prevent accidents. It is suitable for clean media and is not recommended for media containing solid particles and with higher viscosity.
