Which check valve is better for a DN10 pipeline?

Thread Content

Dear sea friends, I have the following question: Condition description: A DN10 nitrogen pipeline, fed by compressed nitrogen at 4–8 kilograms per hour from the factory; after passing through a pressure regulator, the pressure is stabilized at 1–2 kilograms per hour. The temperature is at room temperature. Improvement idea: I now want to add a check valve to the DN10 pipeline to prevent backflow of process gas or certain liquids after the nitrogen supply is stopped, thereby avoiding corrosion of the DN10 solenoid valve. Preliminary idea: Add a swing check valve or a Y-type check valve. Confusion: I’m not sure which of these two types of valves will result in less pressure drop, or will have less impact on the throttling of nitrogen after pressure reduction Are there any valves that are better than these two? Thank you all in advance! ! !
