Jacket insulation off valve professional manufacturers, the factory developed the production of cut-off valve] [reliable quality, reasonable prices, improve service. [Shutoff valve] for a variety of light and heavy industrial and building pipelines. Growth through quality, global sharing jacket insulation off valve is widely used:! Chemical, petrochemical, oil, paper, mining, electricity, gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronics industry, urban construction and other fields ??? Insulation valve principle: insulation valve has a good cold insulation properties, and the valve diameter and the diameter of the same, Weifang stainless steel valves, while effectively reducing the pipeline medium heat loss. Good cold insulation characteristics, while effectively reducing the pipeline medium heat loss. Insulation valves get in petroleum, chemical, metallurgical, pharmaceutical and other types of systems in many applications, valves, reduce the loss of heat medium in the pipe, to prevent the emergence of media resemble crystals solidification. The role of insulation valves are at high or low temperature conditions through the valve, the valve insulation material within the insulating effect of the mediators, the media will not condense or stick to the inside of the valve body, so that the proper functioning of the valve opening and closing. When the heat is turned off valve, the valve opening height, the nominal 25% to 30% of the diameter, the valve brand, traffic has reached the maximum, that valve has reached the fully open position. So off fully open position of the valve, the valve stroke should be determined. Types of liquefied gas cutoff valve stem threads are divided by location external thread type, thread type. According to the flow of media points, straight-through, DC type and angle type. Cut-off valve according to the sealing form points, shut-off valve packing and bellows sealed stop valves. Weifang valves, valve, the valve is provided by Shandong Everbright Everbright Valve Co., Ltd., Shandong. Shandong Everbright Valve Co., Ltd. (www.sdgdfm.com) located in Weifang City, Shandong Province, Cravens District Bao Tong Street North Makers Industrial Park.
