 Application 

 

The high performance butterfly valve is designed with a double eccentric structure. The center of the shaft is offset from the center of the valve body structure, and combined with the design of the circular arc sealing surface of the valve plate, the valve plate is quickly disengaged from the sealing seat when opened to reduce the frictional force of the sealing surface, and the valve plate has better sealing performance when closed. . The center self-positioning sealing valve seat structure design combined with the independent valve seat compensation seal, the valve seat wear is effectively compensated, and the friction force at the time of sealing is reduced, the valve and the operation force are greatly reduced, thereby effectively improving the control precision of the butterfly valve. . This series of butterfly valve seals have a long service life and excellent sealing performance. It is suitable for the adjustment and cutting of dry general corrosive gas liquid medium.

Feature 

 

1. Double eccentric structure is adopted. When closed, the valve plate expands outward to achieve the best peripheral sealing state; when opened, the valve plate and the sealing ring are quickly disengaged, effectively preventing the sealing ring from being worn; thus, the operating torque is reduced and the operating torque is increased. The working life of the valve.

 

2. The sealing ring has novel design and adopts the internationally advanced technology: the PTFE seal adopts the “lip-tooth” self-sealing structure; the hard seal adopts the “U”-shaped elastic seal. The sealing structure has a long service life and is reliable. As for the case of using a soft seal, and under what circumstances a hard seal is used, it is mainly determined by the user's requirements, working conditions and corrosion resistance requirements.

 

3. Pneumatic double eccentric high performance butterfly valve has large circulation capacity and small flow resistance, second only to the same diameter non-reducing O-shaped ball valve.

 

4. Pneumatic double eccentric high performance butterfly valve has large circulation diameter, and the diameter of the flow passage is larger than the diameter of the flow passage specified in GB12238. The flow channel has no shrinkage chamber, which is convenient for pipeline cleaning and self-cleaning. It is more effective for fluids with turbidity, low viscosity with suspended particles and fibrous media.

 

5. The connection method with the pipeline adopts the non-blue clip type. Structure length: soft seal adopts GB12221 series (ISO5752 series code: 20). The hard seal adopts GB12221 long series (ISO5752 series code: 16). Therefore, this type of valve is versatile and interchangeable and is in line with international standards.

 

6. Four standard actuators: pneumatic piston (ZS), pneumatic diaphragm (ZM), electromechanical switch (Za), and electric electronically regulated (ZD) are interchangeable.
