Check valves provide reliable backflow functionality when properly sized.

Based on experience, the minimum operating range of the valve should

be 50% for gases and 40% for liquids in relation to the total capacity of

the valve. Lower flow rates can lead to unstable performance, excessive

noise, and even component failure.
