Main valves in the ammonia synthesis section
Thread Content
Please discuss the main valves used in the ammonia synthesis section, including: operating conditions, valve types, valve manufacturers, and usage status, etc. Feel free to post your comments; thank you!

It is recommended that you look up information online by yourself; there are only a few well-known valve manufacturers across the country
1. Plug valves, gate valves, globe valves, ball valves—used to open or close the flow of medium in pipelines. Globe valves are used to shut off fluids; when fully open, the flow path is completely unobstructed, resulting in the lowest pressure loss for the fluid flow. Gate valves are typically suitable for applications where frequent opening and closing are not required, and where the gate plate needs to remain fully open or fully closed. Not suitable for use as a regulator or throttle. 2. Check valve (including foot valve) — used to automatically prevent the backflow of fluid in the pipeline. 3. Throttle valve—used to regulate the flow rate of the medium in the pipeline. 4. Butterfly valve—used to open or close the medium in the pipeline, and can also be used for regulation. Two sealing types: elastic and metallic. There are two types: wafer-type butterfly valves and flange-type butterfly valves. 5. Safety valves – used on boilers, storage vessels, and pipelines; they automatically release excess pressure when it exceeds the specified level, thereby ensuring the safety of operational processes. 6. Pressure relief valve—used to automatically reduce the pressure of the medium in pipes and equipment. It creates resistance as the medium passes through the gap in the valve disc, resulting in pressure loss and thus achieving the purpose of pressure reduction. 7. Drainer — used on steam pipes to automatically remove condensate, preventing steam loss or leakage. 8. Globe valve—very suitable for shutting off, regulating, and throttling the flow of a medium. 1) Angular globe valve 2) Straight-through globe valve 3) Plunger globe valve
