Detailed Introduction of Standard Stainless Steel Gate Valve Design Features The design features of standard stainless steel gate valves mainly reflected in the following aspects: Material Selection Main body material: 304 or 316 stainless steel is usually used, which not only has good resistance, corrosion resistance, and strength but also ensures the stability of valve performance and service life under various harsh environments. Valve seat material: The valve seat usesTFE (polytetrafluoroethylene) material, which not only has excellent chemical inertness but also has a low friction coefficient, making the valve switch flexible the maintenance cost extremely low. Structural Form Straight-through structure: The design of the J41W model represents a gate valve with a straight-through structure, has significant closing and throttling functions. Nominal pressure and diameter: For example, 16P indicates its nominal pressure is 1.6Mpa (ivalent to about 16 kgf/cm²), and 100 refers to the valve’s nominal diameter, with the unit being millimeters. Performance Parameters pressure and temperature range Working pressure: The working pressure range of J41W-16p-100 is wide, which can meet the system of different pressure levels. Working temperature: It is usually suitable for the working temperature range of -29℃ to 550℃, adapting to a variety industrial environments. Seal performance Low leakage rate: Thanks to the precise manufacturing process and high-quality sealing materials, the gate valve has excellent sealing performance and a low rate. Application scope Standard stainless steel gate valves, due to their excellent corrosion resistance and sealing, have a wide range of applications in many fields: Petroleum chemical industry In the petroleum and chemical industry, stainless steel gate valves are used to control the flow of fluids, ensuring the safety and efficiency of the production process. armaceutical industry The pharmaceutical industry has extremely high requirements for hygiene conditions, and the corrosion resistance and easy cleaning characteristics of stainless steel gate valves make them an ideal choiceFood processing industry In the food processing industry, stainless steel gate valves are used to ensure the hygiene and safety of food during the processing process, preventing pollution. Stand and Specifications Design and manufacturing standards Design and manufacturing are carried out according to GB12235-89 standards. Structural length and flange standards Structural length is according to GB12221-89 standards, and flange size is according to JB/G79-94. Valve inspection and testing standards Valve inspection and testing are carried out according to GB13927 standards. In summary, standard stainless steel gate, with their excellent design features, performance parameters, and wide range of applications, play an important role in many industrial fields
