Fluorine-lined ball valve, as a key equipment widely used in many fields, is gaining more and more attention for its excellent performance and advantages. Its characteristics such as corrosion resistance, sealing performance, low fluid resistance, low friction coefficient, environmental protection and energy saving make it show outstanding performance in chemical, pharmaceutical, food, environment…

Pressure relief valve It is mainly used in situations where the pressure is too high. When the pressure is greater than the set value, the inner plate of the valve is pushed open to release the pressure in time. After the pressure is reduced, it returns to its original position. It is not much different from the safety valve. The pressure relief valve is mostly used for liquids, and the safety va…

Judging whether the electric butterfly valve needs to be replaced is an important task to ensure the safety and stable operation of the system. According to different operating conditions and the specific use environment, operators can judge whether the electric butterfly valve can no longer meet the process requirements and needs to be replaced through the following aspects.…

The tilted design of the valve disc reduces the impact of the fluid on the valve, and the closing process is relatively gentle, reducing the water hammer phenomenon. When the medium flows downstream, the fluid pressure pushes the valve disc to rotate around its hinge, the valve opens, and the fluid passes smoothly. When the medium flows backward, the fluid pressure tilts the valve disc to the cl…

The jacket insulation valve is a conventional valve body with a metal jacket welded on the outside. The temperature of the medium in the valve body can be adjusted by injecting steam, heat transfer oil, cooling water and other media into the jacket to achieve the effect of heat preservation or cold preservation.…

Welded ball valve is widely used in various pipeline equipment such as city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating station, power plant, etc.…

The valve is a control component in the pipeline fluid delivery system…

Diaphragm valve refers to a flexible membrane or a combined diaphragm installed in the valve body and the valve cover, and its closing part is a compression device connected to the diaphragm. …
