Air Separation Valves

 China UTMOST Air Separation Valve 

Air separation units are widely used in important industries such as metallurgy and the chemical industry. Pneumatic control valves are widely used in air separation plants, in order to adapt to changes such as air separation plants becoming larger and technology updates, also gradually have a new design and use ideas and methods. Since extra-large air separation plants are basically used in the chemical industry, the pressure of the product gas will be required to be above several MPa, and the high-pressure difference leads to the high flow rate of the oxygen medium regulating valve. Safety is the first and most important outstanding issue, so choosing the appropriate material is especially critical. In the case of a high flow rate, the valve body is all made of MONEL material or the valve core is made of MONEL material to ensure the safety of the oxygen medium. UTMOST industrial valve factory accurately calculates the flow rate of the gas, strictly follows the international IGC, factory standards, and other standards, selects the appropriate material reasonably, and solves the problem of using the regulating types of control valves used in industry in the air separation plant.

 

China UTMOST Valves Advantages in Air Separation Industry

With the development of air separation plants to extra-large, the caliber of GLOBE valves will be very large. Generally, GLOBE valves with diameters larger than DN250 are difficult to find in the market, and the price will be much higher. If you choose a butterfly valve such as the soft seal butterfly valve, there will be problems such as relatively poor adjustment performance and the inability to adjust small openings. Therefore, at this time, it will be considered to use two pipelines and two valves in parallel. The advantage of this use is that the coordinated control of the two valves has better adjustment accuracy when the opening degree is small. In the initial stage of equipment start-up, one valve is used for adjustment; in normal working conditions, one valve is fully open and another valve is used for adjustment. At present, extra-large air separation plants are mostly used in the chemical industry. Many large-scale coal chemical industries are built in remote areas such as Inner Mongolia. At this time, the impact of the environment on the valve also needs to be considered. Valve accessories for different environments (including positioners, solenoid valves, etc.).
