Function:

A check valve is an automatic device that prevents the backflow of media in a pipeline. It ensures that the pump and motor do not reverse, and it also helps in discharging the contents of a container. Additionally, it can be used in pipelines where pressure might rise above the system’s normal level, acting as an auxiliary safety measure.

Classification:

Based on its structure and installation method, check valves are categorized into two main types:

  1. Swing Check Valve: The disc rotates around the seat axis, offering lower flow resistance compared to lift check valves. It is suitable for low flow rates and large diameters but should not be used in pulsating flows. It can be single-disc, double-disc, or multi-disc, depending on the size and application.
  2. Lift Check Valve: The disc moves vertically within the body. These valves are typically installed in horizontal pipelines and are similar in design to globe valves. They are commonly used for high-pressure, small-diameter applications. The disc is guided by a sleeve, allowing it to open under media pressure and close when the flow stops.

Check valves are essential components in many fluid systems, ensuring one-way flow and protecting equipment from damage caused by backflow. Whether you're looking for industrial-grade solutions or residential use, this product is a reliable choice.
