Installing the low-temperature control valve requires careful attention

Thread Content

　　Control valves used in low-temperature and cryogenic applications are called low-temperature control valves. So, in such a special environment, how can we effectively install low-temperature control valves? 1. Check whether all parts of the machine are missing or loose. For media that are harmful to human health, tests for strength, sealing, leakage, and accuracy must be conducted. 2. Clean the pipes and valves before installation to remove impurities and grease. Especially in situations where the use of oil is prohibited, users can specify their requirements regarding cleanliness. When selecting a lubricant, it is necessary to take into account the contraindications of the working medium in order to prevent accidents. 3. When flanging the valve body to the pipeline, pay attention to coaxiality. A flexible connection should be used as much as possible between the flanged connecting plate installed on the upper valve cover and the cryogenic tank. 4. The installation site should take into account the safety of personnel and equipment, ensuring ease of operation as well as facilitating disassembly, assembly, and maintenance. 5. The valve should be installed upright and vertically on horizontal pipelines; if that is not possible, it can be installed at an angle. In situations where the valve is significantly tilted or subject to vibrations, it must be secured using a support frame. 6. The flow direction of the medium should be consistent with the arrow on the valve body. The air flow should be dry and oil-free. The valve should operate at an ambient temperature of -30 to 60°C. 7. Bypasses should be provided to ensure continuous production even if the automatic control system fails or the valves need to be maintained. The flow characteristics and stroke of the bypass valve must be consistent with those of the original valve. 　　Installing a low-temperature control valve requires careful attention. The points mentioned above are some tips for installing such valves, and I hope they will be helpful to everyone!
