It is always best practice to include at least one priming valve for every pump connected to the priming system. However, even a properly sized priming system will not operate as desired if there are flow restrictions caused by improperly selected valves or piping.
The shape and size of an orifice determines the amount of air that can flow through it at any given pressure level. Like all valves, priming valves have flow limitations due to internal orifices and connection sizes that can negatively impact priming if they are restrictive.
When determining which priming valve should be selected for an application, the size and number of priming valves that are needed will impact the valve selection. Q-VAC’s vacuum experts will ensure that each priming system, including the priming valves, are sized properly for peak performance and efficiency.
