2-inch brass spring check valves are commonly used in various applications, such as plumbing, industrial systems, and water treatment, to prevent backflow and ensure the one-way flow of liquids or gases. These valves use a spring-loaded mechanism to keep the valve closed until the flow pressure opens it. Depending on the design and application, several types of 2-inch brass spring check valves are available, each offering specific benefits.

Single Spring Check Valves

Single spring check valves are the most common type used in various systems. They feature a single spring that holds the valve closed until the fluid pressure exceeds the spring's force, causing the valve to open and allow flow in one direction. These valves are typically compact and suitable for moderate flow and pressure applications. Their straightforward design makes them an economical choice for standard applications.

Dual Spring Check Valves

Dual spring check valves are designed with two springs that work together to provide enhanced sealing and performance. This type of valve can handle higher pressures and provide a more reliable seal, making it ideal for systems that experience fluctuating pressures or require a stronger backflow prevention mechanism. Dual spring check valves are often used in more demanding applications, such as industrial systems or large-scale water treatment plants.

Wafer-style Brass Spring Check Valves

Wafer-style brass spring check valves have a compact, flat design and are typically sandwiched between two flanges in a pipeline. This design allows for easier installation and space-saving in tight areas. They are commonly used in applications where saving space is crucial without compromising on functionality. These valves are efficient in preventing backflow and can be used in both low and medium-pressure systems.
