Check the velocity thru a 6" Flexi-Hinge® valve at a liquid flow rate of 900gpm.

1. The flow area of a 6" valve is 23.76 square inches.

2. Performing the calculation for liquid applications.
900gpm x 0.3208 / 23.76 sq. in. = 12 ft. / sec.

A velocity of 12 ft./sec. is less than the maximum recommended velocity. A 6" valve would be acceptable with no regard to velocity. A furthur check with respect to the pressure drop should be performed before finalizing the valve selection.
