Intro
POPU Valve: Double Eccentric Butterfly Valve
The valve adopts double eccentric structure, butterfly plate, seat sealing surface processing precision. The butterfly plate is completely detached from the sealing surface at the moment of opening.
The butterfly plate is almost frictionless in the process of closing, and it is easy to close. It has the function of self-locking the tighter the valve is closed, and the sealing performance is stable and reliable.

Advantages
1. The main body material is QT450-10, the chemical composition and mechanical properties of which meet the requirements of the national regulations and standards, and material reports can be provided;
2. All the valve body and parts are processed by CNC machine tools to ensure product precision;
3. Adopting body sealing structure, which is different from the conventional plate sealing structure in the market, and can realize bidirectional sealing;
4. Rubber soft seal and stainless steel hard seal can be selected, the valve plate and other parts can also be selected according to the working conditions of the material;
5. The valve seat surfacing stainless steel, more wear-resistant, longer service life;
6. Valve shaft is supported by self-lubricating sleeve bearing to reduce friction and torque;
7. Adopting world famous brand Akzo epoxy resin spraying, spraying thickness up to 250um.
7. Each valve must be tested in accordance with national standards, and unqualified products will never leave the factory.
