Selection of on-off valves
Thread Content
Medium mixed gas, with a pressure of 0.5 Ma and a temperature of 180–200 degrees Celsius; it contains a small amount of solid particles. The on/off valve starts to leak after just half a year of use
I have used hard-sealed, soft-sealed, and ceramic valves, and the performance of each was not very good
What is damaged inside a valve that has leaked after it has been disassembled? What type of structure does the on-off valve have? Does the medium contain corrosive components?
Gate valves – we have used them in gas-based hydrogen production, and the operating conditions are quite similar to yours, so they should work.
Could you tell me what specific medium it is? Or what process is used?
What is the medium flowing through your pipes? If it is a corrosive medium, valves with an enamel lining are required
They are all pneumatic ball valves; previously, ordinary ones with scratches were used, but now hardened and ceramic versions are used, as they are not corrosive
How is the internal leakage? The gate valve has never been used
