First, the pneumatic clamping butterfly valve seal Product Overview
 Precision   J-shaped elastic ring and three eccentric multi-level metal hard seal   structure, is widely used in the medium temperature ≤ 425 ℃ metallurgy,   electricity, petrochemicals, and water supply and drainage and Municipal   construction and other industrial pipelines, for regulating the flow   and breaking the fluid to use. The valve adopts three eccentric   structure, the valve seat and the disc sealing surface are made of   different hardness and stainless steel, has good corrosion resistance,   long service life, the valve has a two-way sealing function, the product   complies with national GB / T13927-92 valve pressure Test Standard. 
 
 Second, the pneumatic clamp butterfly valve features
 1, the valve adopts three eccentric seal structure, the valve seat and   disc almost no wear, with the more the more tight sealing function. 
 2, the ring made of stainless steel, with the advantages of both metal   seal and flexible seal, both in the case of low temperature and high   temperature, have excellent sealing performance, with corrosion   resistance, long service life and so on. 
 3, the butterfly plate sealing surface using welding cobalt-based hard   alloy, sealing surface wear-resistant, long service life. 
 4, Large-format butterfly plate frame structure, high strength, large flow area, small flow resistance. 
 5, the valve has a two-way sealing function, the installation is not   subject to restrictions on the flow of media, but also the location of   space, can be installed in any direction. 
 6, the drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly.

 Third, the pneumatic clamp-type seal butterfly valve principle
 Electromagnetic valve to control the pneumatic actuator, the valve stem to achieve the purpose of turning 90 °.

Cylinder with 1/4 rotary cylinder, adjustable angle 1 ° ~ 5 °.

Fourth, the main technical parameters

Note: Other special sealing materials or special temperature can also be designed according to customer requirements
 

 Fifth, the pneumatic clamp on the main parts of the butterfly valve seal material

Note:   Other parts and seals of the material can also be based on the actual   conditions or customer requirements design selection 
 
 Six , pneumatic clamp-type seal butterfly valve main dimensions

Note:   According to different valve torque, different air pressure and   different actual conditions, select the appropriate actuator size also   changes its relevant
