Electric high-temperature and high-pressure valve

1、 The main purpose of electric high-temperature and high-pressure valves (globe valves) is flange connected globe valves, which are suitable for cutting or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with a nominal pressure of PN1.6~16MPa and a working temperature of -29~550 ℃. The driving methods include manual, gear transmission, electric, pneumatic, etc.

2、 The structural characteristics of electric high-temperature and high-pressure valves (globe valves) are: 1. The selection of materials is exquisite, in accordance with relevant domestic and foreign standards, the structure is reasonable, and the appearance is beautiful. 2. The sealing surfaces of the valve disc and valve seat are made of iron based alloy overlay welding or Stellite cobalt based hard alloy overlay welding, with good wear resistance, high temperature resistance, corrosion resistance, scratch resistance, and long service life. 3. The valve stem has undergone tempering and surface nitriding treatment, providing good corrosion resistance and scratch resistance. 4. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements. 5. The valve body material variety is complete, and fillers and gaskets can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions. 6. The reverse seal is made by connecting the sealing seat with threads or welding austenitic stainless steel on the body, which is reliable in sealing. Replacing the filler can be done without stopping the machine, making it convenient and fast without affecting the system operation. 7. Equipped with the DZW series multi turn electric device, it has a small shell, light weight, full functionality, and can be used with remote computers. Electric devices can also be selected according to user requirements.
