Question by: Dean C on Oct 19, 2025, 9:04 PM

flow rate on this valve is listed two ways it seems, 90 liters per minute and also 60 gpm. which one is right or are those just different units sayin the same thing?

Answer by: Customer Support on Oct 21, 2025, 8:32 AM

Both figures are correct and refer to the same valve. The 90 liter per minute rating and the 227 L/min at 60 USgpm rating represent two different flow conditions documented for this valve. The 90 L/min figure is one operational flow rate, while the 227 L/min is the maximum flow capacity expressed in both metric and US gallon units. So you're getting a valve rated up to 5000 psi that can handle that higher flow when your system calls for it.
