Hydrogen compressor inlet and outlet valves of the hydrogenation unit

In hydrogenation units, the selection of inlet and outlet valves for hydrogen compressors is based primarily on the following factors: 1. Valve material: Due to the high permeability of hydrogen, the material of these valves must be able to prevent hydrogen leakage effectively; common materials include stainless steel and copper alloys. 2. Sealing performance of valves: Due to the high sensitivity of hydrogen to its environment, the sealing performance of the inlet and outlet valves must meet high standards to ensure the safe operation of the system. 3. Corrosion resistance of valves: Hydrogen is corrosive; using valves with good corrosion resistance can extend their service life. For the selection of inlet and outlet valves, the following two types of valves can be considered: 1. Track ball valve: A track ball valve is a valve with good sealing properties and strong corrosion resistance, making it suitable for use in hydrogenation units. Orbit ball valves are available in both domestic and imported versions; the choice should be made based on specific requirements and budget constraints. 2. Ball valve: The ball valve is also a commonly used type of valve, and it can be employed in hydrogenation units as well. Ball valves are available in various materials and models; choose the appropriate one based on specific requirements and budget. It should be noted that selecting the appropriate inlet and outlet valves requires taking into account actual conditions and professional advice to ensure safe and reliable operation. .
