RPV Options 
RPV (Remote 
Proportioning Valve) 
This option allows the system to use a remote 
proportioning valve to mix two different 
materials, typically virgin and regrind materials, 
during a convey cycle. Touching RPV repeatedly 
at the Station Setup screen steps through the 
three choices. 
Enable this option with PLC control if you will be 
adjusting the mix from the controller’s touch 
screen. 
Enable this option with local control if the station 
operator will be adjusting the mix using a timer 
box at the station.

RPV material B 
Percentage of the additive material to be 
included in the mix. This setting applies only 
when RPV is enabled with PLC control. The 
system is set up so that, if there are any 
inaccuracies in the proportions, the mix will 
contain more Material A and less Material B 
than specified here. 
Ø –99% 
30% 
Cycle time 
Number of seconds for each cycle in depositing 
Material A and Material B during the convey 
time. This setting applies only when RPV is 
enabled with PLC control. Example: If you set 
convey time to 30 seconds, cycle time to 10 
seconds, and Material B to 30% (so Material A 
is 70%), the system will convey as follows: 
Material A for 7 seconds 
Material B for 3 seconds (end cycle 1) 
Material A for 7 seconds 
Material B for 3 seconds (end cycle 2) 
Material A for 7 seconds 
Material B for 3 seconds (end cycle 3) 
In a volume-fill station, a cycle will be truncated 
before completion if the station becomes full. 
The cycle time should divide evenly into the 
convey time.
