Screwed Swing Check Valve

Features of Screwed Swing Check Valve

The screwed swing check valve is a type of check valve in which the disc swings freely on a hinge or trunnion mounted in the body. The disc is held closed by the pressure of the line fluid against the disc and opens when the upstream pressure drops. It is designed with a threaded connection and therefore can be used in pipelines with low pressure. It has good flow characteristics and tight shut-off. It is easy to maintain and repair. It can be used in a wide range of applications, including water supply, gas supply, petrochemical, and power generation. It is available in a variety of sizes, materials, and pressure classes. Its main advantages are easy installation, low-pressure drop, long life, and economical cost.

Applications of Screwed Swing Check Valve

Screwed Swing Check Valves are commonly used in a variety of industrial and commercial applications. They are most often used in applications that require the prevention of backflow. This type of valve is designed to open when the pressure on the inlet side of the valve is greater than the pressure on the outlet side. When the pressure on the outlet side is greater than the inlet side, the valve will close and prevent the flow of liquids or gases. They are also used for controlling the flow of water and other fluids in pipelines and in various machines. Another application of screwed swing check valves is in the regulation of steam flow in high-pressure systems, such as those in power plants. In addition, they are used in pneumatic systems, such as those used in industrial control systems. The screwed swing check valve is also used in the production of carbonated beverages, as well as in the brewing industry.
