Class Information
Number: 137/101
Name: Fluid handling > Self-proportioning or correlating systems > Self-proportioning flow systems > Flow comparison or differential response > Flow dividers (e.g., reversely acting controls)
Description: Systems in which a flow is divided into a plurality of flow paths and the ratio between the flow in each branch maintained in response to means sensing differences in flow or pressure in each branch by throttling one branch an amount equal to the amount the other branch is opened.
