Product Overview

FROM THE BOOSTER PUMP UNIT
Application: Distribution circuit with booster pump
Application: High/low flow
Small valve is set to the desired outlet pressure set point. It will handle all demand up to the point where the small valve's "falloff" pressure reaches
the setpoint of the larger valve, at which point the larger valve will open to handle the increasing demand. The set point difference between the small
and larger valves ranges from 7 to 10 psi.
Example:
1) 3 gpm to 30 gpm required flow range at 70 psi.
2) 3/4" valve will handle 2 to 12 gpm flow range.
3) 1-1/4" valve will handle 5 to 35 gpm flow range.
