Product description of flange gate valve:
Flange gate valve is applicable to nominal pressure PN1 Cut off or connect the pipeline medium on the pipelines of various systems of petroleum, chemical, hydraulic and thermal power plants with working temperature of 6 ~ 16.0mpa and working temperature of ≤ – 29 ℃ ~ 550 ℃. The applicable media of flange gate valve are: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. the operation modes are: manual, gear drive, electric, pneumatic, etc.
Structural features of flange gate valve:
1. Exquisite material selection, in line with relevant domestic and foreign standards, reasonable structure and beautiful appearance. 2. The sealing surface of valve disc and valve seat is made of iron-based alloy surfacing or Stellite cobalt based cemented carbide surfacing. It has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life. 3. The valve rod has good corrosion resistance and scratch resistance after quenching and tempering and surface nitriding treatment. 4. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements. 5. The valve body has a complete variety of materials, and the packing and gasket can be reasonably selected according to the actual working conditions or user requirements, which can be applicable to various pressure, temperature and medium working conditions. 6. The inverted seal is made of threaded connection seal seat or body surfacing austenitic stainless steel. The seal is reliable. The replacement of filler can be carried out without shutdown, which is convenient and fast and does not affect the operation of the system.
Product description of flange gate valve:
Flange gate valves are commonly used in the series of products. The gate valve adopts an elastic 5-degree slope structure with good sealing performance. The sealing surfaces of the gate valve and valve seat are made of Stellite cobalt based cemented carbide with different hardness. They have reliable sealing, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long service life. Flange gate valves are widely used in petrochemical industry, thermal power plants and other oil products The water vapor pipeline is used as an opening and closing device to connect or cut off the medium in the pipeline.
