Pneumatic light weight ventilating butterfly valve
Pneumatic tripple offset butterfly valve features:
1. Using Solidworks 3D model of optimal design
2. Using three eccentric multi-level hard-seal structure, in the 0-90 ° Switching process, the valve plate and seal without any friction, reduces the open and close torque, increased service life.
3. All the modular design, production and interchangeability strong. Seal with the valve seat with removable interchangeable structure, and easy installation and maintenance. Cut off the tight, two-way sealed pressurized each contributed to the positive and negative zero leakage.
