What is the difference between dn800 pneumatic telescopic ball valve and mass flowmeter? 2. The opening pressure difference of angle stroke pneumatic valve is very large
The opening pressure difference of angle travel valves is very large. Because the torque of the drive shaft caused by the cooperation of materials on the valve core or valve body is very small, it can bear a large pressure difference.
1、 Intelligent pneumatic butterfly valve Intelligent pneumatic butterfly valve uses precision U-shaped elastic seal ring and three eccentric multi-level metal hard seal structure, and is widely used in metallurgy, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃, to regulate flow and carry off fluid. The valve adopts a three eccentric structure. The sealing surface of the valve seat and disc plate is made of stainless steel with different hardness. It has good corrosion resistance and long service life. The valve has a two-way sealing function. The product complies with the national GB/T13927-92 valve pressure test standard.
