The sealing performance of a valve directly affects the control effect of the fluid medium and the safe operation of the system. Grinding the valve sealing surface is one of the important means to ensure its sealing performance. Its main purpose is to eliminate unevenness, defects, and particles on the sealing surface, improve the surface […]
Faced with numerous valve classifications and complex operating conditions, selecting the most suitable valves for pipeline systems requires, first, understanding valve characteristics; second, mastering the steps and criteria for valve selection; and third, adhering to the principles for selecting valves used in the petroleum and chemical industry. The principles for selecting valves in the petroleum […]
Valves are control components in fluid transport systems. They can be used in fluid control systems to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Standards for Determining Internal Leakage in Valves The method for determining internal leakage in valves is […]
Check valve refers to a valve whose opening and closing part is a round disc and acts by its own weight and medium pressure to block the backflow of the medium, which belongs to the automatic valve.The motion mode of the valve disc is divided into lifting type and swinging type.Lift Check Valve is similar with […]
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. Common Valve […]
A butterfly valve is a type of valve whose closing part (valve disc) is a disc that rotates around the valve stem to open and close. It is mainly used for pipeline shut-off and throttling. The disc is driven by the valve stem, and a 90°rotation completes one opening and closing cycle. By changing the deflection angle […]
