valveOpen
valveOpen is a term in fluid control and process automation that denotes a valve in its open state or capable of conducting flow. In practice it can be a boolean status used by control software or the measured valve position relative to its closed and fully open stops.
Valve opening is typically expressed as a percentage, a flow coefficient (CV), or an angle. Data from
In software and automation hardware, valveOpen supports interlocks, alarms, and sequencing. An open valve may permit
