RDV 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 hard metal, ceramics and other wear-resisting materials, which has good mechanical and wear-resisting properties. It solves the problem that the sealing surface is easy to be eroded due to material erosion and has a low life. 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, so as to make the overall operation safe and economical. Significant improvement.
Z644HC 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.
Z644TC Ceramics Double Plate Gate Valve adopts double valve plate, and the sealing pair adopts high-grade toughening structural ceramics manufactured by nanotechnology. Its practical performance is much higher than that of ordinary structural ceramics, cemented carbide and other wear-resistant materials. It solves the problem that the sealing surface is easy to be eroded due to material erosion, and its service life is not high. Its service life is 5-10 times longer than that of ordinary material valves, which brings reason to users. The desired use effect and economic benefits are conducive to equipment detection and operation adjustment, thus significantly improving the overall operation safety and economy.
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.
The valve plate on one side adopts original hole design, small start-up load and no plug phenomenon in the valve chamber. On the other side, the valve plate is sealed with carbide on one side, which has strong wear resistance, good sealing performance and long service life.
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.
YDF Pneumatic Dome Valve are switches for gas conveying solid materials, which play the role of opening and separating pipe space. It is suitable for the sealed conveying system of loose, dry, non-sticky and flowable solid materials, especially for the ash and slag treatment system of thermal power plants.The closing section of the dome valve is realized by a spherical mesh core and an inflatable banana seal, and the opening and closing of the dome valve are carried out under the pressure-free state, thus realizing the accurate displacement without connection between the two valves.
1. Valve sealing pair is made of special formula material, which has the properties of temperature resistance, corrosion resistance and wear resistance.2. Small and portable, simple structure, easy to disassemble and assemble, suitable for a variety of media, temperature does not exceed 150 C.3. Good sealing performance.4. Small operating torque and quick opening.5. Clear display of switch position.6. Installation position and angle are not limited.
ZNF Series Check Valves is a kind of check valve, which plays a one-way role in the pipeline to prevent reverse flow of medium. It is widely used in pipeline equipment of various departments.
Anti-clip Wear-resistant Check Valve uses alloy material with good wear resistance as the main sealing material, and improves the reliability of low pressure pipeline media can also be closed. The product is widely used in electric power, petroleum, chemical industry, smelting and other industries.
