Gate valves with fluid resistance are very small, and the applicable pressure, temperature range, etc. are one of the commonly used shut-off valves for cutting off or connecting to the medium in the pipeline.
At present, there are three commonly used design structures for gate valves in China in the 1970s. Compared to gate valves, advanced countries such as the United States and Japan have larger structures, incomplete types of body materials, and unreliable sealing performance. Especially for PN1.0MPa low-pressure gate valves, there is only cast iron material in China. The cast iron gate valve body often suffers from serious problems such as cracking and gate plates. Cast iron gate valves are prone to rusting carbon steel, and the quality of the packing gasket is poor, resulting in serious internal and external leakage. For corrosive media conditions, there is a lack of suitable PN1.0MPa stainless steel gate valves for low-pressure systems in China. Stainless steel gate valves have alternative solutions with higher pressure levels, which not only increases project or project investment, but also causes unnecessary waste of stainless steel materials. This factory is a professional manufacturer that imported supporting valve equipment. For many years, we have been engaged in importing domestic valves and continue to absorb advanced valve technology from abroad. We have accumulated rich experience in design, manufacturing, and quality control. A flange connected steel gate valve with the following characteristics has been developed to address common issues with domestic gate valves Meet the requirements of advanced domestic and international standards, with reliable sealing and excellent performance.
② The valve body material is complete, and the packing and gasket can be adjusted according to actual working conditions or user requirements, suitable for various pressures, temperatures, and medium working conditions.
③ Wedge shaped elastic gate structure, large diameter group rolling bearings, easy to open and close.
④ Multiple standard pipe flanges and flange sealing surface types can be used to meet various engineering needs and user requirements.
⑤ Develop a PN1.0MPa low-pressure carbon steel gate valve, which can replace iron gate valves and effectively solve the advantages of cast iron gate valve shells that are prone to cracking, falling off, valve stem corrosion, and unreliable sealing performance.
⑥ Develop PN1.0MPa series low-pressure stainless steel gate valves that can be applied to various corrosive media conditions, reducing costs and saving materials.
