(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.
