Electric valve: the valve industry for the good of Yangzhou Denso's flagship product, the main use of high pressure valve for flange connection PN PN1.6 ~ 16.0MPa, work temperature ≤ -29 ℃ ~ 550 ℃ oil chemical, water, fire station pipeline of various systems, cut off or connected line media. 
 1, structural features, uses and precautions 
 Can be installed anywhere in the pipeline, the media stream from the bottom up. Product design and manufacturing according to national standards GB12235, reasonable structure, reliable sealing, excellent performance and beautiful shape. Alloy steel valve for high temperature steam, oil pipeline, with a high temperature characteristics. Stainless steel valves for corrosion in various media channels, there are good anti-corrosion of sufficient strength. Its characteristics are as follows: 
 ① valve, valve seat sealing surface is made by welding together hard, wear-resistant, high temperature, corrosion resistance, scratch resistance, long service life. 
 ② nitrided steel stem material, stem after nitriding surface hardness, wear, scratch resistance, anti-corrosion. 
 ③ due to temperature, pressure and other reasons, the valve body bore DN50 below, the valve cover for forging, DN65 above the valve body, valve cover for the steel casting. 
 ④ full range of body materials, packing, gasket according to the actual working conditions or the user's request for reasonable matching, can be applied with all kinds of pressure, temperature and medium conditions. 
 ⑤ When installing the valve the flow of media attention, in strict accordance with the arrow in the direction of the flow valve installed. 
 ⑥ as vertical installation of electric valve stem up. 
 Applicable medium: water, oil, steam, and acid, alkali, ammonia, urea, sulfur and natural gas. Mode of operation are: manual, gear transmission, electric, pneumatic and so on.
