How it Works
The pressure sustaining pilot valve [1] causes the main valve to be slowly closed when the upstream pressure [P1] is lower than the minimum preset pressure, and fully opens when [P1] is in excess of setting. Local manual shut-off of the valve can be performed with the manual Shuttle Valve [2].
