Not familiar with your brand of unit, but in many cases the flow restrictor is built into the outlet fitting on the membrane housing. On my system it's part of a manual flush valve plumbed in downstream of the RO membrane.

These units have a booster pump mine runs 130 ISh, also have auto back flush and a few other features, all in all about 3 or 4 solenoids on top of a normal unit.
