8.4 Continuous Flow
Electric Valves
Electric valves, which provide the best positive valve closure, are
most commonly used in liquefied gas applications. Electric valves
require the pump controller to be equipped with the valve driver
board.
Note
The max flow rate for the E1000 dual system will tend to have
a lower percentage flow rate due to port size restrictions, with
a maximum flow rate equal to that of the E500 system
(see Table 8-5).

8.4.1 Technical
Specifications
Dual system maximum flow rates under optimal conditions are
approximately 65% of the max flow rate for each pump model.
