When using controls to open and close a PRV, PSV, FCV or TCV, I only see the option to set the status to Closed or Inactive. How can I set a control to make the valve active again, to resume controlling the pressure or flow?
To make a PRV, PSV, FCV or TCV inactive or closed for a given condition, you would use the valve status Action.
To make it active again, use the valve setting Action, and set it to the desired hydraulic grade or flow setpoint. For a PRV or PSV, you can also set the "pressure valve pressure" to set the pressure instead of the hydraulic grade.
To close the PRV or PSV
If Tank Elevation = xx ft. (m), Then PRV Pressure Valve Status = Closed.
To make the PRV active:
If Tank Elevation = xx ft. (m), Then PRV Pressure Valve Pressure = yy psi (or Then Pressure Valve Setting = yy ft.)
