Как выбрать между центральным поворотным клапаном, двойным эксцентриковым поворотным клапаном и тройным эксцентриковым поворотным клапаном и их соответствующее применение
Schematic diagram of central butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve Centered butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve are three main structural types of butterfly valves. The core difference lies in the relative position design of valve shaft and sealing surface (eccentric structure), which directly affects sealing […]
How to tell if the sealing performance of industrial valves is good?
How to tell if the sealing performance of industrial valves is good? Sealing performance is a critical factor, ensuring the safe operation of pipeline systems and directly affecting medium leakage risks and equipment longevity. To evaluate valve sealing effectiveness, methods such as visual inspection and pressure testing should be combined with international standards like API […]
The difference between GOST standard valves and GB standard valves
The difference between GOST standard valves and GB standard valves Russian standard valves (GOST) and Chinese national standard valves (GB) differ significantly in standards, design, materials, and applications. Gost valves focus on durability under extreme conditions, but Chinese valves pay more attention to cost-effectiveness and broad applicability. The following comparison outlines these differences with supporting […]
How to Choose the Right Industrial Valves from Different Type Valves
In fluid piping systems, Industrial valves are crucial for controlling equipment and pipeline isolation, regulating flow, preventing backflow, and managing pressure relief. Designed to handle diverse media including air, water, steam, corrosive materials, slurries, oils, liquid metals, and radioactive substances, selecting the appropriate valve requires a thorough understanding of their technical properties, selection processes, and […]
