1. In terms of structure and mechanism: hard seal is the seal between metal and metal, and the sealing sphere and valve seat are all metal. The machining accuracy and process are difficult, and it is generally used in high pressure, usually above 35MPa. Soft seal is metal and non-metallic. The sealing between metals, such as nylon tetrafluoroethylene, is the same as the manufacturing standard. 2. On the sealing material: the elastic soft sealing gate valve
and the hard sealing gate valve are for the sealing material of the valve seat, and the hard sealing is the valve seat The material is precision machined to ensure the matching accuracy with the valve core (ball), generally stainless steel and copper. Soft sealing means that the sealing material embedded in the valve seat is non-metallic material. Because the soft sealing material has a certain elasticity, it is not suitable for processing. The precision requirements are relatively low compared to hard seals. 3. Due to the complex working environment of many chemical and mechanical industries in the manufacturing process, many of them are high temperature and high pressure, the friction resistance of the medium is large, and the corrosiveness is strong. Now technology has advanced, various materials The application of the ball valve
is a must have for anyone who appreciates types of industrial valves to the greatest extent.
