(1) To ensure stable operation and a ± 3° F accurate temperature control
Minimum flow rate is 0 gpm when recirculation flow rate is greater than
or equal to the valve size minimum flow rating.
(2) Suggested maximum flow rate for optimum modulating control
(at 7.5 psid pressure drop).
(3) Maximum recommended differential pressure is 20 psid to ensure stable
operation and accurate temperature control.
