In fluid systems, check valves are crucial parts because they guarantee unidirectional flow and stop backflow. The materials employed in their construction have a significant impact on their functionality, longevity, and suitability for different uses. A number of variables, including fluid type, operating pressure, temperature, and climatic conditions, influence the materials that manufacturers choose. The materials frequently used to make check valves and their particular uses will be discusse

In industrial pipe systems, check valves are crucial parts that guarantee unidirectional flow and stop backflow. Their operation is essential for preventing contamination, preserving system effectiveness, and safeguarding equipment. A number of variables, including fluid type, pressure, and flow conditions, influence the choice of check valve type for a given application. The most popular kinds of check valves utilized in industrial settings are examined below.

Gate valve, also known as knife gate valve, is a commonly used pipeline valve. Its main function is to open or close the fluid in the pipeline. The opening and closing of the gate valve is accomplished by moving the rising stem or handwheel, which makes its operation very simple. The characteristics of gate valves are good sealing, low pressure drop, simple structure, small volume, light weight, etc. They are commonly used in pipeline systems for conveying media such as clean water, sewage, oil

The working principle of butterfly valve is to change the flow rate and direction of fluid by rotating the valve. A butterfly valve consists of a valve body, a valve seat, a valve stem, and a valve disc.
