Disc valve XZF series

pneumaticcarbidefor the petroleum industry

XZF Rotary Disc Gate Valve The valve plate is driven by the rotating shaft, so that the motion of the valve switch is rotating. The piston rod of the pneumatic actuator does not contact with the medium directly, which prolongs the service life of the actuator. The sealing pair is made of cemented carbide and ceramic lamp wear-resistant material, which has good mechanical and wear-resistant properties. It solves the problem that the sealing surface is easy to be eroded and has a low service life due to material erosion. Therefore, it has a longer service life, can bring ideal use effect and economic benefit to users, and is conducive to equipment maintenance and operation adjustment, thus making the overall operation safe and economic. Sex was significantly improved. 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.
