A check valve is an important type of valve, and its function is to prevent the backflow of fluid in the pipeline. In piping systems, check valves are commonly used to protect pumps, valves, and other equipment from damage caused by reverse pressure or backflow. This article will introduce the functions, types, and application scenarios of check valves.

Valves are widely used in various industrial and civilian equipment, and the choice of material directly affects the performance and service life of the valve. When selecting valve materials, it is necessary to comprehensively consider various factors based on the actual working conditions and usage requirements to choose the most suitable valve material.

Overload of an electric valve refers to a situation where the torque demand encountered by the electric valve during operation exceeds its design capacity. This situation can be caused by various factors, such as low power supply voltage, improper torque limiting mechanism settings, and excessively high ambient temperature. Electric valves may encounter overload situations during operation, which not only affects their performance but may also lead to safety accidents.
