Inexpensive Safe Water Tapped by Correcting Control Valve Output
The error output from a control valve can come from a variety of sources: uncontrolled input pressure, uncontrolled input flow rate, inaccurate orifice size or turbulent flow through the system which causes irregularity of flow rates through the system.

The Rationale Behind Valve Characteristics
Back in the “early days,” we were taught that, to properly control flow, we should select a linear valve characteristic when the valve controls more than 25% of the piping system pressure drop at full flow.
