Product Detail

Turbine Drive Hard Seal Butterfly Valve


product description: 
Based on the introduction of foreign advanced technology, the worm gear drive hard seal butterfly valve adopts precise J-shaped elastic sealing ring and triple eccentric multi-level metal hard sealing structure, and is widely used in metallurgy, electric power, petrochemical industry and medium temperature ≤ 425 °C. Industrial pipelines such as water supply and drainage and municipal construction are used to regulate the flow and to shut off fluids. The valve adopts three eccentric structure. The valve seat and the disc plate sealing surface are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The valve has two-way sealing function, and the product meets the national GB/T13927-92 valve pressure. Test Standard. 
  
Features: 
1, the valve adopts three eccentric sealing structure, the valve seat and the butterfly plate almost no wear, with more and more tight sealing function. 
2. The seal ring is made of stainless steel. It has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance under low temperature and high temperature conditions, and has the characteristics of corrosion resistance and long service life. 
3, the plate sealing surface using surfacing cobalt-based carbide, sealing surface wear resistance, long service life. 
4. The large size butterfly board adopts truss structure, high strength, large flow area, and small flow resistance. 
5, the valve has a two-way sealing function, the installation is not limited by the flow of the media, but also by the location of space, can be installed in any direction. 
6, the drive device can be multi-station (rotated 90 ° or 180 °) installation, user-friendly. 



 
Lining material: PTFE/FEP/PFA/GXPO.First, the characteristics of sanitary wafer type butterfly valve 
 
1, the design is novel, reasonable, unique structure, light weight, rapid opening and closing. 
 
2, small torque, easy operation, effort and dexterity. 
 
3, can be installed anywhere, easy maintenance. 
 
4, sealing material, anti-aging, corrosion resistance, long service life and other characteristics. 
 
Second, the principle of sanitary wafer type butterfly valve 
 
Sanitary wafer type butterfly valves are used in dairy products, food, pharmaceuticals, beer, cosmetics and other industrial fields. All parts in contact with the media are mirror-polished. The sealing ring Ф25-Ф108 can be used in two ranges: EPDM, silicone (SI), Ф57 and below is EPDM; the opening and closing parts reciprocate about 90° to open, close and adjust the fluid. A stainless steel butterfly valve. 
 
Hygienic wafer clip type butterfly valve not only has the advantages of simple structure, small size, light weight, material consumption, small installation size, small driving torque, simple and quick operation, but also can have good flow regulation function and close sealing property at the same time. When it is fully opened, it has a small flow resistance, and it can perform sensitive flow control when it is opened between about ° and 70. Therefore, in the field of large-diameter adjustment, the movement of the valve plate is wiping off. It can be used for media with suspended solids and can also be used for powdered and granular media depending on the strength of the seal. 
 
Third, the use of sanitary wafer type butterfly valve 
 
Hygienic wafer-type butterfly valves use standard electronic polishing with a smooth surface to ensure clean, no media storage area, and no potential contamination. Quickly disassemble the valve, make the valve open and repair quickly and easily, and shorten the process downtime. With a compact structure, easy assembly and disassembly. Sanitary wafer type butterfly valves are widely used in process control applications such as food, pharmaceuticals, cosmetics, clean steam, alcohol, beverages, and biochemical industries. 
 
Fourth, sanitary clamp type butterfly valve sealing performance: 
 
Sanitary wafer type butterfly valve is a stainless steel soft seal butterfly valve in the middle line. The sealing principle is that when the valve plate is processed, the sealing surface has a suitable surface roughness value. The synthetic rubber valve seat forms a suitable rough surface of the sealing surface during the compression molding. value. When the stainless steel butterfly valve is closed, through the rotation of the valve plate, the outer circular sealing surface of the valve plate presses the synthetic rubber valve seat, so that the synthetic rubber valve seat generates elastic deformation and the elastic force acts as a sealing ratio to ensure the sealing of the valve. 
V. Hygienic wafer-type butterfly valve manufacturing inspection standards
