FR1-20 - Flow Regulator
Fixed, pressure compensated
227 L/min (60 USgpm) • 210 bar (3000 psi)
Operation
This valve maintains a
constant flow from port 1 to
port 2 based on 5.5 bar(80
psid) regardless of pressure
changes downstream on port
2. Reverse flow from port 2
to port 1 is at the value of
the fixed orifice and is non-
pressure compensated.
