Bleed hole sizes shown above are based on a percent of full effective port area of the valve. This does not necessarily indicate the percent of valve capacity that will be bypassed.
The hole sizes shown above should be used for reference only. Normal industry practice is to equalize systems 3 to 5 minutes.
