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: What is a stainless steel wafer check valve?

A stainless steel wafer check valve is a type of valve used in piping systems to prevent backflow of fluids. It is called a "wafer" valve because it is installed between two flanges, with the valve body sandwiched between them.

The valve itself consists of a stainless steel body and a movable disc, which is typically made of a durable and corrosion-resistant material such as stainless steel, bronze, or PVC. The disc is held in place by a spring or hinge mechanism, and when fluid flows through the valve in the forward direction, the disc lifts and allows the fluid to pass through. However, when the flow reverses, the disc is pushed back into place by the spring or hinge, creating a seal that prevents backflow.

Stainless steel wafer check valves are commonly used in applications where backflow prevention is critical, such as in water treatment plants, sewage systems, and chemical processing plants. They are typically compact and lightweight, which makes them easy to install and maintain. Additionally, stainless steel is a highly durable and corrosion-resistant material that can withstand harsh environments and aggressive fluids, which makes it a good choice for applications where reliability and longevity are important.
