Imported pneumatic control valve
Imported pneumatic control valve product overview
American YLOK imported pneumatic control valve adopts double-guide structure, equipped with multiple spring actuators, and has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly. It is widely used in the precise control of gas, liquid, steam and other media, and the process parameters such as pressure, flow, temperature and liquid level are kept at a given value. It is especially suitable for the occasions where the allowable pressure difference is large and the allowable leakage is large and not very clean medium. This series of products has many varieties such as standard type, bellows sealed type, jacket heat preservation type. The nominal pressure rating of the product is PN10, 16, 40, 64; the valve body diameter ranges from DN20 to 800. The applicable fluid temperature ranges from -200℃ to +560℃, and there are many grades within its range. Leakage standards are level II or IV. The flow characteristic is linear or equal percentage. A variety of varieties and specifications to choose from
Features of imported pneumatic control valve
The top, bottom and layer double-guided double-seat regulating valve has good stability during operation.
There are two valve cores and valve seats, and the "four-way" valve body is adopted, which can be easily converted from the front installation to the reverse installation, and the air-close valve becomes the air-open valve.
The valve body is designed according to the principle of fluid dynamics with a constant cross-section flow channel with low flow resistance and a large rated flow coefficient.
The unbalanced force is small and the allowable pressure difference is large.
The actuator adopts a multi-spring structure and the height is reduced by 30%. 30% weight reduction.
The adjustable range is large, and the inherent adjustable ratio is 50%.
