ZDKW Electric Wafer Butterfly | hard seal butterfly valve Product Overview Electric Wafer butterfly valve seals in the form of electric folder into (three eccentric metal seal, midline soft seal, double eccentric soft seal) in several forms, the use of rotary electric actuator and folders butterfly valve body, electric butterfly valve can be used on site requirements clip space is quite narrow, short distance pipeline occasions. Butterfly valve body without rod, bolts, etc., reliable, long life, you can multi-station installation, the flow of influence from the media. Wafer butterfly valves are widely used in electric dust cold or hot gas pipeline chemical, building materials, power plants, glass and other industries in ventilation, environmental engineering, as a medium to regulate the flow of gas or cut-off device. Electric butterfly valve on the main features of a folder, novel design, reasonable, unique structure, light weight, open and close quickly. 2, seals can be replaced, reliable sealing performance to achieve bi-directional sealing zero leakage. 3, sealing materials aging, corrosion resistance, long life and other characteristics. 4, two-piece stem no pin connection, simple structure, easy maintenance. 5, seating and backrest integrated structure, reducing seat deformation. 6, the valve stem axial positioning means, to enhance sealing, the torque reduction valves. 7, can be installed in any location, and easy maintenance. Electric Wafer butterfly valve main technical parameters of the valve body in the form of straight casting nominal diameter DN50 ~ 1000mm Nominal PN1.0,1.6,2.5MPa Flange Standard JIS B220, JB / T79, ANSI B16.5-1981, GB / T9113, HG20594-97, HG20618-97 and other forms of flange connection, right clip-on valve cover in the form of integral type gland packing plate Clamp V-type PTFE packing, flexible graphite packing
