Double Plate Gate Valve refers to Australian "Armstrong" valve technology and has been successfully developed by researchers for many years. The valve is replaced by double valve plate and the sealing pair is made of wear-resistant metal. Scope of application It is suitable for opening and closing of gas and slag in dry ash system of power plant, as well as for opening and closing of abrasive, corrosive, powder and flue gas in mines, steel, papermaking and petrochemical industries. Key Points of Installation and Use 1. Read this instruction carefully before installation, and check valve type, size and technical parameters. 2. It is strictly forbidden to Weld flanges after installing valves. The valve installation distance reserved from the pipeline shall be appropriate, and gaskets shall be added on both sides of the flange. 3. The center of the two pipelines and the center of the valve diameter should be coaxial, the flange surface should be flat, and the flange surface should not be allowed to have larger bias, so as to ensure the clamping and normal operation of the valve. Tightening bolts should be uniform and symmetrical. Product characteristics 1) There is no obstruction in the full flow of the inlet and outlet, and there is blocking device, so there is less dry ash and ash accumulation. 2) Metal seal with high temperature. 3) Good wear resistance and long service life. 4) Civilian display of switch is accurate. 5) Can be installed at any position and angle.
