pneumatic soft seal butterfly valve overview :

 
The pneumatic soft seal butterfly valve is a specially designed and carefully manufactured product based on the introduction of foreign advanced technology. The pneumatic soft seal butterfly valve is equipped with travel limit switch, solenoid valve, triplet and 0.4-0.7mpa air source to realize the switch operation, and send two pairs of passive contact signals to indicate the valve switch. When adopting intelligent control and positioning, it can be matched with domestic electric valve positioner, input 4-20madc signal and 0.4-0.7mpa air source to realize intelligent control, and realize the adjustment of pressure, flow, temperature, liquid level and other parameters.
 
Pneumatic soft seal butterfly valve is driven by compressed air, and the valve stem drives the valve core to rotate 90 ℃ in the valve body, which can realize the action of full open and full close. Before and after putting into operation, the pneumatic soft seal butterfly valve shall be maintained professionally, which plays an important role in the production and operation of the valve. Correct and orderly and effective maintenance will protect the valve, make the valve function normally and extend the service life of the pneumatic soft seal butterfly valve.
 
pneumatic soft seal butterfly valve features:
 
1. The valve adopts double eccentric structure, which has the sealing function of closer and tighter, and the sealing performance is reliable.
 
2. The sealing pair material is stainless steel and NBR oil resistant rubber, with long service life.
 
3. The rubber seal ring can be located on the valve body or the butterfly plate. It can be applied to different media for users to choose.
 
4. The butterfly plate adopts frame structure with high strength, large flow area and small flow resistance.
 
5. The whole baking paint can effectively prevent corrosion and can be used in different media as long as the sealing material of sealing valve seat is replaced.
 
6. The valve has a two-way sealing function, which is not controlled by the flow direction of the medium during installation and is not affected by the space position. It can be installed in any direction.
 
7. The valve has unique structure, flexible operation, labor saving and convenience.
