A valve for the injection bridge

hr

Siggy showed me one of these recently. You set the GPM and read it in the window. A simple accurate way to set the injection flow. This one is from the Watts Radiant catalog. www.istec-corp.com has them also.

REHAU has been selling them for many years now. They have 4 pages of this stuff in their catalog.

Is that a differential pressure by-pass valve?

Thanks, Ant

Here is a PAB

pressure activated bypass, alsocalled a differential by pass valve. It is a valve that opens progressively as the pressure in a circuit increases. In multi zone valved system for example as the zone valves start closing it allow a portion of the flow to bypass.

The flow setting valve in the first post allows you to set one fixed flow. Useful on a circuit where you need an exact GPM flow, as in injection mixing.
