Labor-saving operation: The medium pressure on the ball generates all the force to the upper and lower bearings, the ball body will not move relative to the position, the sealing force of both ends of the seat is uniform, and the operating torque is low. The spring preloaded movable metal seat structure can be used for high temperature, high pressure and various media pipelines. According to customer requirements, can be designed to be suitable for media containing particles, slurry and so on. Widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, paper and other media pipelines.
Product characteristics
1. Anti-vulcanization stress cracking: the material of the valve contact medium is selected according to the standard of NACE 01-75 of the American Society of Corrosion Engineers, and the surface nickel plating is performed according to the standard, which can meet the requirements of the vulcanization environmental conditions.
2. Using polymer or metal as sealing material, it has excellent sealing performance in high temperature and high pressure conditions.
3. Set the packing box to prevent the valve stem from flying out due to abnormal pressure rise in the valve cavity, and add the inverted sealing structure to ensure the reliable sealing of the packing.
4. Widely used in chemical, oil refining, oil and gas, natural gas, steel and other media pipel
