High vacuum butterfly valve door high vacuum butterfly valve is change the direction of gas path through electromagnetic directional valve, cylinder driving butterfly valve door for opening and closing motion control execution. GIQ series high vacuum butterfly valve door is suitable for the high vacuum system used to put through or cut off the airflow in vacuum line function. Applicable medium for pure air and noncorrosive gases. Pneumatic high vacuum butterfly valve gate is to use compressed air to power. Changing direction of the gas circuit by pneumatic device, perform cylinder drive butterfly valve door for opening and closing movement. Pneumatic high vacuum butterfly valve door optional feedback signal device and electric gate valve locator. According to medium pressure vacuum gate valve can be divided into low vacuum valve door: vacuum range for low vacuum 105 & ZWJ; To 10 - 2Pa( In 760-10) High vacuum valve gate: vacuum range of 105 to 10 ~ 10 - high vacuum 4Pa( ~ 10-760 6) Ultra-high vacuum gate valve: vacuum range for 10 to 10 - ultra high vacuum 7 pa ( ~ 10-760 Design and manufacture according to JB/T4079 - 1991 standard execution; Inspection and testing in accordance with the JB/T6446 - 1992 standard execution; The flange size JB919, GB/T6070 standard execution. High vacuum butterfly valve door main parts material of valve body, disc: carbon steel, Nickel plating) 13 cr, stainless steel, stainless steel components: butterfly plate sealing ring: nitrile rubber, fluorine rubber filling material: nitrile rubber
