|Product pressure||1.0Mpa-2.5 Mpa|
|Body material||Cast steel, stainless steel 304, 316, 316L|
|Valve plate material||Cast steel, stainless steel 304, 316, 316L|
|Drive mode||Worm gear, manual, pneumatic, electric|
Second, the main features of the hard-sealed pneumatic wafer-type butterfly valve:
1. The design adopts the principle of three eccentricity, the sealing is separated, the contact is closed, and the sealing performance is reliable;
2. The sealing ring is made of stainless steel. Under high temperature and cold conditions, the seal has no stress deformation, and has the characteristics of high temperature resistance, corrosion resistance and long service life.
3. The axial positioning device solves the problem of wear and leakage of the axial sealing surface, and the transmission device can be installed in any direction;
4. The flow area is large, the flow resistance coefficient is small, and the circulation capacity is strong;
5, anti-aging, anti-radiation, durable;
6, the seal can be adjusted, 100,000 life without leakage.
Third, the implementation standard of hard-sealed pneumatic wafer type butterfly valve:
|Manufacturing Standards||GB/T 122387-89|
