Figure 6.5 Scheme using Block Valves to Inject
In the diagram above, the solenoid-operated Additive Block Valves are used to select the additive that is to be
delivered. In contrast to the previous scheme, an additive Injector Valve is not used. During a load, the Additive
Block Valve of the selected additive is opened only when an injection is commanded. This is accomplished by
wiring the Additive Block Valve output in series with the Additive Injection output. Refer to the schematic below.
