Injection valve operation
The valve has a stator and a rotor. Refer to Figure 8 . The rotor has three pathways. The liquid moves
through the pathways. The alignment of the pathways with the ports on the stator control the
direction in which the liquid flows through the valve. Refer to
Table 1 for the ports on the six-port
injection valve. The injection valve has two positions: the inject position and the load position. Refer
to
Inject position on page 9 and Load position on page 9. The valve moves bi-directionally
between those two positions. When the system is not in operation, the valves stay in the inject
position.
