Which type of check valve is better?

Which type of check valve is good – one with sensitive operation and a long lifespan? Please recommend one!
This needs to be chosen based on factors such as the pressure, medium, temperature, and properties of the fluid required on-site. The relatively lightweight butterfly check valves look good. But it still depends on the specific conditions on site for you to make a choice.
Actually, this is a difficult question to answer – each check valve has its own range of applications and suitable environments. I think if you can provide specific operating conditions, it will help others make the right decision for you!
