Details

Applications

Wafer check valve is a type of check valve that is used to regulate and control the flow of fluids through pipelines while preventing backflow. High quality wafer check valve is typically used in applications where space is limited, such as in HVAC systems, water treatment plants, and industrial processes.

Tips: Swing Check Valve vs. Wafer Check Valve

Swing check valves and wafer check valves are both types of check valves that are used to prevent backflow in pipelines, but they differ in their design and application. Here are some of the key differences between swing check valves and wafer check valves:

• Design: A swing check valve has a disc that swings on a hinge to allow flow in one direction and prevent backflow in the other direction. A wafer check valve, on the other hand, has a disc that is held in place by a spring or other mechanism, allowing flow in one direction only.
• Installation: Swing check valves are typically installed between flanges and require more space for installation due to their larger size. Wafer check valves, on the other hand, have a compact design and are installed between flanges with the help of bolts.
• Pressure drop: Swing check valves have a higher pressure drop than wafer check valves, which can impact the efficiency of the system. Wafer check valves have a lower pressure drop, which can help to maintain the efficiency of the system and reduce energy costs.
• Material: Swing check valves are available in a range of materials, including cast iron, ductile iron, and stainless steel. Wafer check valves are also available in a range of materials, but they are often made of plastic or cast iron.
• Application: Swing check valves are typically used in applications where a higher flow rate is required and where there is more space available for installation. Wafer check valves are often used in applications where space is limited and where a lower pressure drop is desired.

In summary, swing check valves and wafer check valves are both effective in preventing backflow in pipelines, but they differ in their design, installation, pressure drop, material, and application. Choosing the right type of check valve depends on the specific needs of the system and the application requirements.
