Check valve

Industrial valves are key devices used to control and regulate the flow of fluids (including liquids, gases and slurries) and are widely used in many industrial fields such as petroleum, natural gas, chemical industry, electric power, metallurgy, pharmaceuticals and food processing. Its main functions include opening and closing pipes, regulating flow, controlling flow direction, regulating and controlling system pressure, and preventing backflow. According to the different functions and structures, industrial valves can be divided into the following categories: Gate Valve, Ball Valve, Butterfly Valve, Globe Valve, Check Valve, Safety Valve, Control Valve.

When selecting industrial valves, it is necessary to comprehensively consider the characteristics of the medium (e.g., corrosivity, Viscosity, solid content, etc.), operating conditions (such as temperature, pressure, flow, etc.), valve material, connection and operation (manual, pneumatic, electric, etc.). Correct selection and maintenance can significantly improve the safety, reliability and operational efficiency of the system.
