TECH TIPS
When using the Limitem as a one-pipe device,
a 40 scim (11 ml/s) restrictor will limit your
output to 80% of supply. A 20 scim (5 ml/s)
restrictor will limit your output to 60% of supply.
Example: With a 20 scim (5 ml/s) restrictor and
25 psi (11.3 kPa) supply, your maximum output
is 15 psi (6.8 kPa).
