By understanding their functionalities, it’s possible to gain insights into the significant role that wafer check valves play in different industries.

What is a Wafer Check Valve?

Wafer check valves are mechanical devices that permit fluid discharge in one direction while preventing backflow in the opposite one. They are installed between two flanges, providing a space-saving and compact design. There are various types of wafer check valves, including swing check valves and dual plate check valves. Swing check valves feature a hinged disc that swings open to allow forward discharge and swings shut to prevent backflow. On the other hand, dual plate check valves consist of two plates that open and close in response to the flow direction, offering a compact design and fast response time.

Design and Features of Wafer Check Valves

These valves operate based on the principle of fluid pressure and flow direction. When fluid flows in the desired direction, the force of the flow lifts the check valve’s disc, enabling the fluid to pass through. However, in the event of reverse flow or backflow, the disc closes, preventing the fluid from flowing backward and protecting the system from damage. Additionally, one of the significant aspects to consider when using wafer valves in systems is the valve size and weight. The correct sizing and weight are crucial in ensuring optimal performance and efficiency within the system.

Significance of Valve Size and Weight in Systems
