USING AND SETTING THE BALANCING VALVE
Presetting
The 130 series balancing valve features highly graduated adjustment which facilitates pre-setting. In commercial balancing applications where multiple
balancing valves are used, significant labor time can be saved in the balancing process if in advance of being installed, the valves are pre-set to the
expected knob position value. To pre-set, the anticipated pressure drop across the valve is required. For example, if balancing valve item 130500A
(3/4”), water is the fluid, and it has been calculated that a pressure drop of 1.5 psi across the valve will result in a flow rate of 3.5 gpm in the circuit,
we can see from the chart below that the knob value should be preset to a value between 2.5 and 3.0 with interpolation indicating approximately
position 2.9.
