Selection of valve material
Thread Content
There is a on/off valve that requires fast closing; the details are as follows: Medium: ETHYLENE / VAM ； Size: 1 inch ； Temperature: 315℃ ； Pressure: 37.8 MPa g. Question: What type of on/off valve should be selected, and are there any special requirements regarding the material?
Due to its corrosive nature, it is recommended to use a ball valve lined with PTFE; if cost is a concern, a titanium version can be chosen, but it is too expensive
I’m sorry I didn’t examine your operating conditions carefully; given the high temperatures and pressures, it’s better for you to choose a titanium alloy ball valve core. The valve body can be made of alloy, as such high pressures require forged materials.
The valve body needs to be forged; the pressure is too high. CL4500。
The medium is high-pressure ethylene/vinyl acetate, which is somewhat corrosive. The pipes and valves used in this process system are mostly imported. Check the valve material table provided by the process package supplier.
Find more foreigners; their choices will reflect the technical requirements
There are many domestic agents for imported valves. If you look for suppliers abroad, the prices are too high, and the contracts are drawn up in US dollars. I’d like to consult with the domestic agent
