Section 5 Continuous Flow Introduction, Installation, & Operation
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 E1000D 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 E500D system
(see Table 5-5).

E65DM, E260D, E100DM, E100DX
Note
Electric valves are not available for the 65D and 500HPx
pumps. Please consult the factory for options.
Electrical valves can only be used with pumps A, B.
Dual system maximum flow rates under optimal conditions are
approximately 65% of the max flow rate for each pump model.
0.35 bar, at system backpressures from 6.9 bar to the single
